DSLR’S

Top 10 DSLR’S in 2016
      A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor. The alternative would be to have a viewfinder with its own lens, hence the term "single lens" for this design. By using only one lens, the viewfinder of a DSLR presents an image that will not perceptibly differ from what is captured by the camera's sensor.
DSLRs largely replaced film-based SLRs during the 2000s, and despite the rising popularity of mirrorless system cameras in the early 2010s, DSLRs remained the most common type of interchangeable lens camera in use as of 2014.
For decades, the DSLR (digital SLR) has been the top choice for anyone who wants to take their photography to the next level. Whether you're a beginner or a pro, a DSLR offers three key ingredients: manual controls, excellent picture quality and interchangeable lenses.
A DSLR is still the cheapest way to get a camera with interchangeable lenses and a viewfinder (entry-level mirrorless cameras don't have viewfinders) and, at the other end of the scale, almost all professional sports, press and wildlife photographers choose full-frame DSLRs over every other camera type.
In between are a whole range of digital SLRs aimed at different users, different levels of experience and different budgets. Here's the list of Top 10 DSLR’S in 2016:

1. Canon EOS 5DS

Sensor: Full-frame CMOS | Megapixels: 50.6 | Autofocus: 61-point AF, 41 cross-type | Screen type: 3.2-inch, 1,040,000 dots | Maximum continuous shooting speed: 5fps | Movies: 1080p | User level: Expert| 

With three cameras in its entry-level range Canon already had plenty to interest novices and enthusiast photographers on a budget. Now the company has replaced the 700D with two models, the EOS 760D and 750D, rather than one. As the 700D continues in the line-up (for now at least), this means that there are five cameras in what Canon calls its beginners' range. The new 760D and 750D, known as the Rebel T6s and T6i in the USA sit at the top of this group above the 700D, 100D and 1200D.
While the 750D could be considered the more logical upgrade to the 700D and is aimed at novices, the 760D is designed with more experienced photographers in mind and it has a few features from Canon's high-end cameras.
Although they are aimed at slightly different people, the Canon 750D (Rebel T6i) and 760D (T6s) are essentially the same camera as they share many components. For a start they both have Canon's new APS-C format CMOS sensor with an effective pixel count of 24.2 million, a Digic 6 processing engine and an autofocus system with 19 cross-type points for use when focusing images in the viewfinder.
The cameras can select the appropriate AF point to use automatically in 19-point AF mode, or it can be set manually in groups in Zone AF mode (there are five groups of points for selection) or individually in Single point AF mode.

2. Nikon D810

Sensor: Full-frame CMOS | Megapixels: 36.3MP | Autofocus: 51-point AF, 15 cross-type | Screen type: 3.2-inch, 1,229K dots | Maximum continuous shooting speed: 5fps | Movies: 1080p | User level: Expert

Nikon''s D800 and D800E caused great excitement when they were first announced in February 2012 largely because of their groundbreaking 36 million pixel count. These two full-frame SLR cameras are identical apart from the fact that the D800E's sensor has a weaker anti-aliasing (AA) or optical low-pass filter (OLPF) to enable it to deliver sharper details straight from the camera.
Thanks to their impressive detail resolution the two cameras quickly went to the top of the wishlist for many professional and enthusiast photographers, especially those looking for a comparatively lightweight camera for landscape, still life or macro photography. They have remained firm favourites ever since, setting the bar for resolution by which other cameras are judged.
Now the replacement for these two cameras has been announced in the form of the 36.3Mp Nikon D810, one camera without an anti-aliasing filter to replace both models. Interestingly, we have been told that while the D800E was widely reported as having no AA filter, the filter over the sensor did actually have some anti-aliasing element and this has now been completely removed from the D810's filter.
This should enable the new camera to record even more detail than before, and Nikon is claiming that the D810 produces 'the highest image quality in Nikon's history'. Omitting the AA filter brings increased risk of moire patterning in images, but it hasn't been found to be a major issue for D800E users

3. Nikon D500

Sensor: APS-C CMOS | Megapixels: 20.9MP | Autofocus: 153-point AF, 99 cross-type | Screen type: 3.2-inch tilting touchscreen, 2,359,000 dots | Maximum continuous shooting speed: 10fps | Movies: 4K | User level: Expert

For a long time the top slot in Nikon's APS-C (DX) format SLR line-up was occupied by the popular D300S, but that camera dates from 2009 and production ceased ages ago, leaving a vacancy that Nikon photographers have been wanting to see filled for years.
During that time there's been plenty of rumour and speculation, but earlier this year, as I headed out to the Consumer Electronics Show (CES) in Las Vegas, I had a hunch that Nikon might be about to deliver what so many photographers had been hoping for.
Happily I was right, and the D500 was announced alongside Nikon's new flagship, the D5. The D500 is aimed at serious enthusiast and professional photographers who want a smaller, lighter camera than a full-frame (FX) model such as the D810 or D5. It's also designed for pros who want the focal length magnification of the DX-format sensor.
One surprise about the D500 is that its APS-C sensor has 20.9 million effective pixels, less than the company's other recent (24MP) DSLRs of the same format; this is to enable the photosites to be bigger, to improve low-light performance.

4. Canon EOS 7D Mark II

Sensor: APS-C CMOS | Megapixels: 20.2MP | Autofocus: 65-point AF, 65 cross-type | Screen type: 3.0-inch, 1,040,000 dots | Maximum continuous shooting speed: 10fps | Movies: 1080p | User level: Expert

As the Canon 7D was launched way back in 2009, its update is somewhat overdue and there have been rumours of a Mark II version for quite some time. Now at last the Canon 7D Mark II has been revealed and can take its place as the manufacturer's flagship APS-C format camera. Canon is claiming that it will produce 'best in class' image quality.
Although the new camera has a 20.2-million-pixel sensor like the Canon 70D , we are told that it is a new device. The micro lenses have also been redesigned for improved efficiency (i.e. light transmission) and this should contribute to an improvement in image quality.
What's more, this sensor is coupled with Dual Digic 6 processing engines to make the camera faster and more responsive. This enables a maximum continuous shooting speed of 10 frames per second (fps) for 31 raw files or until the card is full with JPEGs; and a native sensitivity range of ISO 100-16,000 with expansion settings taking it up to ISO 51,200.
That's the highest non-expansion setting in any Canon SLR. The maximum continuous shooting rate can be set to 2-10fps in High mode, 1-9fps in Low and 1-4fps in Silent shooting mode.

5. Canon EOS 80D

Sensor: APS-C CMOS | Megapixels: 24.2 | Autofocus: 45-point AF, 45 cross-type | Screen type: 3.2-inch tilting touchscreen, 1,040,000 dots | Maximum continuous shooting speed: 7fps | Movies: 1080p | User level: Intermediate5. Canon EOS 80D

The new 80D, which replaces the 70D launched in July 2013, sits smack in the middle of Canon's SLR line-up, above the 760D and below the 7D Mark II.
That puts it in prime enthusiast territory, which means it needs to appeal to people who want to shoot a range of subjects in a variety of conditions. These users also want an extensive feature set with plenty of control options, but they don't need a full-on professional-grade camera.
Canon has given the 80D a new 24-million-pixel sensor along with a Digic 6 processing engine. This may sound similar to the 24Mp 750D and 760D, but these lower-level cameras have Hybrid AF III devices, not the Dual Pixel CMOS AF sensor of the 80D.
The 80D's sensor and processor combination brings a native sensitivity range of ISO 100-16,000 (a third of a stop higher than the 70D), and a maximum expansion value of ISO 25,600 (the same as the 70D).
And while the maximum continuous shooting rate is the same as the 70D's at 7fps, the burst depth has been increased to 110 JPEGs or 25 raw files when a UHS-1 SD card is used; that's a significant step up from the 65 JPEG or 16 raw files possible with the 70D.
Modern SLRs have two autofocus systems, one for when using the camera conventionally and composing images in the viewfinder (i.e. in reflex mode) and the second for use in Live View and video mode. Canon has improved both of these systems for the 80D in comparison with the 70D.

6. Nikon D7200
Sensor: APS-C CMOS | Megapixels: 24.2MP | | Autofocus: 51-point AF, 15 cross-type | Screen type: 3.2-inch, 1,229,000 dots | Maximum continuous shooting speed: 6fps | Movies: 1080p | User level: Intermediate

Roughly two years have elapsed between the introduction of the D7100 and the arrival of its successor, and on the surface the new D7200 seems more like an incremental update than a major overhaul.
The D7200 is built around a sensor with a resolution of 24.2 million pixels, a tiny increase on the D7100's 24.1 million pixels, and the body is identical, with the same weight and dimensions, and the same viewfinder.
In common with its predecessor, the D7200 has no anti-aliasing filter in front of the sensor, an innovation designed to produce sharper images and better rendering of fine detail. Anti-aliasing filters are used to prevent moiré, or interference effects, when photographing fine textures or patterns, but at the time of the D7100's launch, Nikon claimed that the high pixel density of its sensor would make it unlikely to suffer from any moire patterning and we've not seen any reports from users suggesting it's a problem.
There are some significant improvements over the D7100, however, the first of which is the upgrading of the camera's internal processor from the Expeed 3 to the newer and more powerful Expeed 4.
The frame rate remains the same as the D7100 - 6fps at full resolution, or 7fps when using the 1.3x crop mode - but the faster processor delivers improved buffering capacity, which was one of the biggest let-downs in the previous model.

7. Nikon D750

Sensor: Full-frame CMOS | Megapixels: 24.3MP | Autofocus: 51-point AF, 15 cross-type | Screen type: 3.2-inch tilting, 1,229,000 dots | Maximum continuous shooting speed: 6.5fps | Movies: 1080p | User level: Intermediate

Full-frame photography used to be the preserve of professional photographers, but SLRs like the Canon 6D and Nikon D610 have made it a more realistic proposition for amateur and enthusiast photographers. Nikon's latest full-frame camera, the D750 sits above the D610 and the Nikon D810 in the company's range, giving enthusiasts another model to choose from.
At the heart of the D750 is a newly designed 24.3-million-pixel CMOS sensor and an Expeed 4 processing engine. Unlike the 36Mp D810, the new camera has an anti-aliasing filter over the sensor.
This sensor and processor combination enables a native sensitivity range of ISO 100-12,800 with extension settings taking this to ISO 50-51,200. It's also possible to shoot at up to 6.5 frames per second (fps) and record Full HD video at up to 60p. While 6.5fps is a fair rate, some sports photographers may have been hoping for something a bit higher, perhaps 8fps or more.
Enthusiast videographers will also appreciate the stereo microphone and headphone ports along with the ability to fine-tune audio levels in isolation before and during recording. It's also possible to select the sound range (wide/voice) for adjustment. Wind noise can also be reduced when recording with the built-in microphone.
When shooting in Live View or video mode, there's a handy Zebra pattern display to indicate on the screen which areas are in danger of burning.

8. Pentax K-1

Sensor: Full-frame CMOS | Megapixels: 36MP | Autofocus: 33-point AF, 25 cross-type | Screen type: 3.2-inch tilting, 1,037,000 dots | Maximum continuous shooting speed: 4.4fps | Movies: 1080p | User level: Enthusiast/expert

Pentax is one of the big traditional photographic brands to make the transition from film into digital camera manufacturing, and it always seemed likely that it might one day make a full-frame digital SLR. However, it wasn't until February 2015 that the company announced that it was planning to take that step - and now, after a year of looking at mock-ups under glass domes at trade shows, we finally have the Pentax K-1.
Specification-wise the new camera has plenty to attract enthusiast photographers - especially those who still have a collection of full-frame K-mount optics. For starters, the full-frame (35.9 x 24mm) 36 million-pixel sensor (supplied by Sony), 14-bit PRIME IV processing engine and 33-point SAFOX 12 autofocus system are new.
Furthermore, to enable greater detail resolution the sensor has no anti-aliasing (AA) filter; instead Pentax has included its AA filter simulator to reduce moire patterning when needed. This system uses a combination of in-camera software and micro vibrations at a sub-pixel level during the exposure to reduce moire patterning.
Pentax likes to make good use of the ability to shift the sensor in its cameras, and it's no different with the K-1. The primary purpose of the technology is to compensate for accidental movements, and the Shake Reduction II system acts across 5 axes, having a claimed 5-stop impact.
There's also the clever Astro Tracer system, which uses data from the GPS system to guide the movement of the sensor during exposures of up to five minutes to record stars as sharp dots rather than streaks. And let's not forget the sensor-shifting composition adjustment and level correction options.

9. Nikon D3300

Sensor: APS-C CMOS | Megapixels: 24.2MP | Autofocus: 11-point AF, 1 cross-type | Screen type: 3.0-inch, 921,000 dots | Maximum continuous shooting speed: 5fps | Movies: 1080p | User level: Beginner

Despite the growing popularity of mirrorless cameras, the entry-level DSLR market is still incredibly popular for those looking to take the next step in their photography journey.
Nikon''s range of D3xxx models has proved incredibly popular over the years for new users looking to expand their creativity thanks to their blend of easy handling and solid performance, backed-up by an impressive range of lenses and accessories.
The D3300 is the latest in that line, so let's take a look to see if it's the perfect choice for the new user. The D3300 features a high resolution 24.2MP APS-C sensor, with Nikon deciding to omit the low-pass filter this time round. What does this mean? It should mean the even more detail is captured, resulting in even sharper images compared to previous models like the D3200.
In addition to this, the native sensitivity range runs from ISO100 to 12,800, and there's an expansion setting that takes it to the equivalent of ISO25, 600, providing plenty of flexibility for a range of lighting situations.
Like the Nikon D5300 , the D3300 sports Nikon's now second-generation processing engine, the EXPEED 4, allowing the D3300 to shoot continuously at a maximum rate of 5fps, while it can sustain this burst rate for up to 100 fine quality JPEGs. More than enough for most people's needs.

10. Canon EOS Rebel T6i / Canon EOS 750D

Sensor: APS-C CMOS | Megapixels: 24.2MP | Autofocus: 19-point AF, 19 cross-type | Screen type: 3-inch articulating touchscreen, 1,040,000 dots | Continuous shooting speed: 5fps | Movies: 1080p | User level: Beginner/enthusiast

With three cameras in its entry-level range Canon already had plenty to interest novices and enthusiast photographers on a budget. Now the company has replaced the 700D with two models, the EOS 760D and 750D, rather than one. As the 700D continues in the line-up (for now at least), this means that there are five cameras in what Canon calls its beginners' range. The new 760D and 750D, known as the Rebel T6s and T6i in the USA sit at the top of this group above the 700D, 100D and 1200D.
While the 750D could be considered the more logical upgrade to the 700D and is aimed at novices, the 760D is designed with more experienced photographers in mind and it has a few features from Canon's high-end cameras.
Although they are aimed at slightly different people, the Canon 750D (Rebel T6i) and 760D (T6s) are essentially the same camera as they share many components. For a start they both have Canon's new APS-C format CMOS sensor with an effective pixel count of 24.2 million, a Digic 6 processing engine and an autofocus system with 19 cross-type points for use when focusing images in the viewfinder.
 The cameras can select the appropriate AF point to use automatically in 19-point AF mode, or it can be set manually in groups in Zone AF mode (there are five groups of points for selection) or individually in Single point AF mode.
The cameras also have Canon's new Hybrid CMOS AF III system (with Face detection, Tracking AF, FlexiZone-Multi and FlexiZone-Single modes) for use when images or video are composed on the screen in Live View mode. This Hybrid system has a greater number of focusing pixels arranged in a more regular array than in the past, and Canon says it's about 4x faster than version II (used in the EOS 100D) and two generations ahead of the original Hybrid CMOS AF system in the EOS 700D.

CES 2017

The 10 Innovative Products at CES 2017
CES (formally known as the Consumer Electronics Show) is an annual trade show organized by the Consumer Technology Association. Held January at the Las Vegas Convention Center in Las Vegas, Nevada, United States, the event typically hosts presentations of new products and technologies in the consumer electronics industry.
The first CES was held in June 1967 in New York City. It was a spinoff from the Chicago Music Show, which until then had served as the main event for exhibiting consumer electronics. The event had 17,500 attendees and over 100 exhibitors; the kickoff speaker was Motorola chairman Bob Galvin. From 1978 to 1994, CES was held twice each year: once in January in Las Vegas known as Winter Consumer Electronics Show (WCES) and once in June in Chicago, known as Summer Consumer Electronics Show (SCES).
CES 2017 has been the biggest year so far for the annual Consumer Electronics Show in Las Vegas, Nevada. More than 175,000 attendees converged on the strip this week to be among the first to see what the world’s top technology companies have to offer. Car tech took center stage for much of the show, which is certainly understandable considering all the disruption sweeping the automotive industry right now. Connected devices were a top theme once again as well, as the Internet of Things continues its shift from fantasy to reality.
There was plenty to take in at CES 2017, and we had a blast checking out all of the exciting new gear headed to store shelves in 2017 and beyond. In this post, we’ll focus on 10 products in particular that rose above the rest and really wowed us at CES.
1. Faraday Future FF 91

Tesla turned the auto industry on its head when it released the Model S, and rival automakers have had no choice but to embrace electric cars far sooner than they would have liked. There are some truly exciting cars in the works, but nothing else we’ve seen in development comes anywhere close to packing in as much innovation as the Faraday Future FF 91.
The Gardena, California-based startup has had a difficult time this past year due to financial woes and several executive departures. But Faraday has managed to stay the course, and the company wowed CES 2017 attendees on Tuesday night when it finally took the wraps off its first production car.
Faraday Future’s FF 91 is an entirely new breed of automobile, and it’s scheduled to enter production next year. We were lucky enough to tour Faraday’s labs and even go for a ride a couple weeks before CES began, so be sure to check out our first impressions of the FF 91.

2. LG Signature OLED TV W7

An iPhone 7 is 7.1 mm thick. A number 2 pencil is 6 mm thick. LG’s new Signature OLED TV W7 television is 2.59 mm thick.
This stunning next-generation television truly represents the future, packing 4K Ultra HD resolution and HDR into a razor-thin panel that practically becomes part of the wall thanks to a special magnetic mounting system. The components are offloaded into an accompanying sound bar, and the result is a design that will literally reshape televisions for years to come.

3. Ford Alexa integration

Amazon’s virtual personal assistant Alexa was everywhere at this year’s CES, and for good reason. Alexa facilitates a seemingly endless range of functionality and electronics companies are eager to make use of it, rather than having to build their own voice-powered assistant solutions. Of all the Alexa integrations we saw, however, Ford stood out from the crowd.
Ford SYNC 3 AppLink puts everything Alexa offers at a driver’s fingertips. Them home integration will also allow people to start their car, lock and unlock the car, and even check fuel levels using Alexa commands with any compatible Amazon or third-party device. The video above runs through the highlights.

4. Samsung Chromebook Plus

Samsung’s just-announced Chromebook Plus is everything a person could want from a Chromebook in 2017. The 12.3-inch touchscreen display features Quad HD resolution and support for a built-in S Pen stylus. The 2.0GHz hexa-core processor packs plenty of power.
The nifty hinge design allows the screen to rotate all the way open so the device can be used as a tablet. And it ships with the Google Play store preinstalled, giving users access to millions of Android apps in addition to apps made for Chrome OS.
Best of all, preorders are live right now, and the Chromebook Plus starts shipping the week of February 5th.

5. Energous WattUp

This is the second consecutive year that Energous has made our Best of CES list, and both times it was for the company’s WattUp long-range wireless charging solution.
WattUp is no longer just an exciting futuristic technology only available in demos. Energous announced a number of partnerships that will see a number of commercially available products launch with support for the first version of the WattUP wireless charging solution.
This first round of devices have to be within a few inches of the charging transmitter in order to refuel, but Energous plans to launch longer-range transmitters later this year and they will be backward compatible with all previously released devices.

6. AirTV Player

The AirTV Player in an Android-powered box that combines the ability to stream online video services -- including Netflix, Sling TV and other apps available in the Google Play Store -- and access live over-the-air TV channels, too.
While nearly every TV can already receive those free channels with the addition of a cheap antenna, the AirTV is offering the convenience of combining them with the online services into a "one-stop shop," without the annoyance of switching inputs. It unifies the antenna-based channels into the Sling TV online channel guide, too.
AirTV supports up to 4K resolution, as well as 2.4 and 5GHz Wi-Fi. The Bluetooth remote incorporates voice, too, and it has dedicated buttons for Netflix and YouTube.
Note, however, that it lacks both local and cloud DVR capabilities, which Sling TV is also missing. (A Sling TV cloud DVR service is in beta.) No timeshifting for you!
The AirTV will compete with newly announced 2017 products such as the new Tablo Droid, Tablo Live and Mohu AirWave, all of which aim to integrate antenna-based TV channels with online streaming options.

7. TPCast for HTC Vive

Virtual reality is one of the hottest spaces in consumer tech right now, and the HTC Vive offers one of the best VR experiences money can buy. Like all dedicated VR experiences from big-name brands, however, using the Vive means being tethered to a PC. That’s where TPCast comes in.
With financing from HTCs Vive X Accelerator fund, TPCast created a simple solution that connects to the standard Vive headset and converts it into a wireless VR system. In other words, users get the best-in-class VR experience the Vive provides while also enjoying the freedom that a smartphone VR solution affords.
TPCast will initially launch in China, where it will cost just over $215.

8. ODG R-8 and R-9 Smartglasses

Beyond VR, augmented reality is the other half of the computing experience of the future. AR solutions involve overlaying digital elements on top of the physical world around you, opening the door to a wide range of exciting possibilities. Microsoft is leading the way in this space with its HoloLens headset, but ODG’s next-generation R-8 and R-9 smartglasses offer a much more compact solution.
Powered by the same Qualcomm Snapdragon 835 chipset destined to be found in nearly every flagship Android smartphone this year, the R-8 and R-9 smartglasses are both lightweight solutions capable of immersing the wearer in mixed reality.
The higher-end R-9 model features a 50° field of view and 1080p resolution, while the less expensive R-8 glasses have a 40˚ field of view and 720p resolution.

9. AirBar

It's what you've always wanted. A 13-inch MacBook Air with a touchscreen. We've all done the same thing, reaching out to tap or swipe a MacBook before realizing it was, in fact, a MacBook and not a touchscreen Windows laptop. Put a MacBook Air in front of any kid under 10, and they'll instinctively do the same thing.
Only, it's not exactly a MacBook with a touchscreen. It's actually a MacBook with a sold-separately add-on sensor bar that sits just below the display and connects via USB plug. We've played around with one of these devices -- called the AirBar -- late last year, but that version was for Windows PCs.
The AirBar works by sending up a light field that your fingers break by swiping and tapping. In the Windows version we tried, it worked surprisingly well, at least for an add-on that cost less than $70 (£55 or AU$94). The key was to find a laptop with a screen that was precisely the right size for the AirBar, which is why the company has been selling both 13-inch and 15-inch models.
The new MacBook Air version is designed for the 13-inch MacBook Air and costs $99 , although models for other Macs are said to be in the works. One for a new MacBook Pro or for the 12-inch MacBook, for example, would need a USB-C plug, rather than the USB-A one used now.

10.  Sleep Number 360 Smart Bed

Gadgets aimed at helping people get more restful sleep each night come and go each year at CES, typically never to be heard from again. Millions of people suffer from sleep disorders of varying degrees, but gadgets and gizmos rarely offer long-term solutions. The Sleep Number 360 Smart Bed, however, looks like the exception to the rule.
Sleep Number’s latest “smart bed” isn’t just another connected mattress that lets owners make adjustments here and there on a remote or a smartphone. This is an entirely new sleep solution that monitors each partner individually and makes adjustments on its own to keep people sleeping soundly. This way, as sleeping positions change throughout the night, the bed self-adjusts to optimize the sleep surface and ensure comfort.

Wireless Routers

Top 10 wireless routers in 2016
Every household sporting broadband internet needs a wireless router. Without it, accessing the web on a mobile device will require either a pesky (and quite limited) mobile data plan or a complex workaround. Even older routers are due for an upgrade after a handful of years, thanks to the advent of new technologies such as Netgear's dead spot-deterring Orbi Wi-Fi system and Wi-FI CERTIFIED ac spec improvements.
If you have an existing router, it may be getting to the point where it's a bit long in the tooth, that it doesn't have the latest hardware or support the latest 802.11ac networking standard, which exhibits faster speeds and range, courtesy of directional beamforming. This equates to less time-consuming downloads and nippy web browsing. Plus, today's top-end best wireless routers are blisteringly quick, thanks to a technology called NitroQAM.
You may even be enticed by the benefits of the new software produced by router companies, which make it easier to administer to your home network for necessities like parental controls and even basic maintenance. In most situations, you'll even get to take advantage of USB ports for over-the-air storage or to share printers throughout the house.
Here is the list of top ten wireless routers in 2016 to give your home a high speed internet boost.

1. TP Link Archer AC3200 Wireless Tri-Band Gigabit Router
Speed: 802.11ac: 2x 1300 Mbps, 802.11n: 600 Mbps | Connectivity: 5x Gigabit Ethernet, 1x USB 3.0, 1x USB 2.0 | Features: Dual 802.11ac networks, 1GHz Dual-core processor with three co-processors, Smart Connect| Price: $285.99(amazon.com)

If you have a high-traffic network with multiple clients vying for bandwidth, you may want to consider upgrading to a tri-band router. Whereas dual-band models offer one 2.4GHz and one 5GHz Wi-Fi band, tri-band routers offer one 2.4GHz and two 5GHz bands. The extra 5GHz band goes a long way in easing wireless network congestion and gives you more control over how clients connect wirelessly.
With the TP-Link AC3200 Wireless Tri-Band Gigabit Router Archer C3200, you get good 5GHz throughput and a slew of management settings, and it does a solid job of transferring files to and from attached USB storage devices. However, it can't match the overall performance of its triple-band competitors.
The C3200 is an AC3200 router; its 2.4GHz band has a maximum data-link speed of 600Mbps and each of the 5GHz bands can reach speeds of up to 1,300Mbps. It is powered by a 1GHz dual-core processor and supports the 802.11 b/g/n/ac networking standards.
 In addition to Beamforming, which sends Wi-Fi signals directly to clients rather than in a broad spectrum, this router features TP-Link's Smart Connect technology, which, when enabled, automatically assigns the best frequency band to clients based on network traffic.

2. Linksys EA9500 Max-Stream AC5400
Speed: 802.11ac: up to 5.3Gbps | Connectivity: 1 x Gigabit WAN port, 8 x Gigabit LAN ports, 1 x USB 3.0, 1 x USB 2.0 | Features: Easy setup, Tri-band Wi-Fi technology, MU-MIMO, Seamless Roaming| Price: $325.99 (amazon.com)

The EA9500 is a tri-band, quad-stream router with a combined Wi-Fi bandwidth of up to 5,333 megabits per second. Specifically, it has two 5GHz bands, each with a top on-paper Wi-Fi speed of 2,166.67Mbps and its 2.4GHz band tops out at 1,000Mbps. (Read more about Wi-Fi standards here.) The reality, however, is that you won't experience speeds of this magnitude with the EA9500, at least not today. That's because the fastest Wi-Fi clients (such as tablets, smartphones or laptops) top out at just 1,300Mbps. But the powerful specs don't hurt and they also put you in a good position for when clients can reach those ungodly levels of performance.
The router supports Multi-User Multiple Input Multiple Output (MU-MIMO), which is a technology designed to efficiently handle Wi-Fi bandwidth in homes with clients of different speed grades. Each client can connect to the router at its highest speed without adversely affecting the speeds of others.
Looking like a giant mechanical spider, this router is primed for anything from gaming to professional work. The AC5400 is outfitted with a single 2.4GHz band that can reach up to 1000 Mbps, in addition to two 5GHz radios that max out at 2,167Mbps. Together, it adds up to a whopping 5.3Gbps.
This router brings a plethora of features including MU-MIMO, a dual-core CPU, beam forming and eight adjustable antennas. Its coolest feature is "Smart Connect", which lets you assign separate SSIDs for the two 5GHz bands, allowing you to have one network purely for your gaming desktop PC, and another for media streaming or professional work, without the two getting in the way.

3. Asus RT-AC88U
Speed: 802.11ac: 2167Mbps 802.11n: 1000 Mbps | Connectivity: 9x Gigabit Ethernet, 1x USB 2.0 1x USB 3.0 | Features: 1024-QAM, MU-MIMO, WTFast Gamers Private Network, Asus AiProtection, AsusWRT Software | Price: $269.99 (amazon.com)

The Asus RT-AC88U is a dual-band 802.11ac router with a massive feature set and an equally large price tag. It uses Multi-User Multiple Input, Multiple Output (MU-MIMO) technology to serve multiple Wi-Fi clients simultaneously without sacrificing bandwidth. However, each client must contain a MU-MIMO-compatible network adapter in order to take advantage of the technology.
The router is equipped with numerous Gigabit LAN ports and multiple USB ports. The RT-AC88U offers a wealth of management options in a thoughtfully designed user interface and delivers blazing throughput on both the 2.4GHz and 5GHz bands. It's our top pick for high-end routers.
The RT-AC88U is a nice-looking router. It measures 3.3 by 11.8 by 7.4 inches (HWD) and uses a matte-black housing, with a beveled top and angular sides. The front of the router is home to LED indicators for power, wireless activity for both bands, Internet (WAN) connectivity, Wi-Fi Protected Setup (WPS), LAN connectivity, and USB port activity.
 It utilizes a Broadcom 1.4GHz dual-core processor and Broadcom's NitroQAM technology to deliver up to 3,167Mbps of combined (theoretical) throughput (1,000Mbps on the 2.4GHz band, and 2,167Mbps on the 5GHz band).
The Asus RT-AC88U justifies its above-average pricing with unrivalled record-breaking next-generation 802.11ac wireless performance. With four antennas and NitroQAM technology, which pushes speeds further still, this router enables wireless performance that can break the 1GB/sec limit.
There's a minor catch - you'll need to invest in a NitroQAM wireless adapter, such as the Asus PCE-AC88, to see those faster speeds. It's worth it though. Coupled with comprehensive built-in software, a generous array of eight external LAN ports and 100MB/sec performance from its USB 3 port, this router is a champion.

4. Netgear Nighthawk X4S VDSL/ADSL Modem Router D7800
Speed: 802.11ac: 1733Mbps, 802.11n: 800 Mbps | Connectivity: 5x Gigabit Ethernet, 2x USB 3.0, 1x eSATA | Features: VDSL 2 modem | Price: $244.99 (amazon.com)

The Nighthawk X4S AC2600 Smart Wi-Fi Router (model R7800) is an updated version of the X4 R7500 and not only is it much faster, its Wi-Fi signal reach much farther. What's more, the new router now supports MIMO, an increasing popular feature that helps boosts the speed for supported Wi-Fi clients in a crowded home. (Note: Netgear has also released a D7800 version of the X4S that includes a built-in DSL modem.)
It's not perfect, however, and shares the same bloated Web interface as previous Netgear routers and having relatively slow network storage performance when coupled with an external hard drive. Nonetheless, if you're looking to cover a large home (of 4,000 square feet or less) and you have a dozen or so Wi-Fi-connected devices, the X4S is a great choice.
4x4 wireless up to 1733 Mbps for great wireless performance VDSL 2 modem Lacks 1024-QAM Requires special hardware to use fastest speeds
Netgear's D7800 wireless router also has four antennas and can deliver much faster speeds than a standard 802.11ac router, which again, depends on using a compatible adapter or bridge. It comes with two USB ports and an eSATA connector for a huge amount of connectivity, and a VDSL 2 modem built-in. The software is pretty good too, with a simple Dynamic QOS system to make it easier to manage a home network with a massive amount of devices.
5. Linksys WRT1900ACS
Speed: 802.11ac: 1300 Mbps, 802.11n: 600 Mbps | Connectivity: 5x Gigabit Ethernet, 1x USB 2.0, 1x USB 3.0, eSATA | Features: OpenWRT compatible, LinkSys Smart Wi-Fi support | Price: $174.99 (amazon.com)

The WRT1900ACS is the updated version of Linksys’ flagship router of 2015, the WRT1900AC. It packs in a faster processor and double the RAM of its predecessor, which should result in faster overall performance – particularly in more demanding multi-user scenarios.
Otherwise, it's a similar beast to before, capable of up to 1900AC Wi-Fi speeds with its dual-band, four-aerial setup. It also has four Gigabit Ethernet ports, a USB 3.0 port and a combi eSATA/USB 2.0 port for sharing files or printers.
In addition, it continues to supports the open-source router firmware OpenWRT, making it potentially ideal for those users who want to fine-tune their network.
With three wireless streams, the Linksys WRT1900ACS is a less expensive proposition than the above quad-stream 802.11ac routers, and while it doesn't offer the same blistering performance, it still packs performance and great software. Its internals are very powerful.
A dual-core 1.6 GHz processor and 512MB of memory drives a great-looking software interface that makes it a doddle to set up and customise a home network, with a built-in VPN, great wireless range as well as fast external connectivity via USB.

6. D Link EXO AC1750 WiFi Router DIR-869
Speed: 802.11ac: 1300 Mbps, 802.11n: 450 Mbps | Connectivity: 5x Gigabit Ethernet | Features: Dual-core processor | Price: $131.67 (amazon.com)

Even the fastest laptops, tablets and phones have a capped Wi-Fi speed of 1,300Mbps -- no device on the market currently is capable of anything more. So purchasing a top-tier router, like one that supports AC5400 or AC2400 speed standards, will not likely bring you any speed benefits.
The new D-Link EXO DIR-879 is an AC1900 router, meaning that as far as real-world performance goes, it's as fast as you can get, until devices with faster Wi-Fi standards become available.
The EXO is part of a new line of routers from D-Link with a new orange-and-black design and collapsible non-detachable antennas. The look is pleasing to my network world-weary eyes.
 With four Gigabit LAN ports and one Gigabit WAN port on the back, and four collapsible antennas on the sides, the DIR-879 also nails it on practicality. With no USB port or SD card slot, however, which would allow you to easily share a drive with everyone on your network, you'll instead need to connect that drive to a computer on the network.
With four wide antennas that look like solar panels, the orange DIR-869 is a mid-range router from D-Link that uses the company's flat, angular design. It doesn't do anything particularly clever, but is still fast enough to work with the vast majority of all wireless hardware on the market at maximum capacity. It's a dual-band model with a dual-core processor, driving a minimalist but slick software interface. 2.4GHz up to 450Mbps and and 5GHz up to 1300 Mbps is covered.

7. Asus RT-AC68U
Speed: 802.11ac: 1300 Mbps, 802.11n: 600 Mbps | Connectivity: 5x Gigabit Ethernet, 1x USB 3.0, 1x USB 2.0 | Features: Asus AiProtection, AsusWRT Software | Price: $234.33 (amazon.com)
This is Asus’ second 802.11ac router and follows the hugely successful RT-AC66U - the fastest wireless ac router we have tested, until now.

Asus isn’t sitting on its laurels though, as the AC68U upgrades almost every aspect of its predecessor and there is a new design, chipset, upgraded processing power and the addition of a USB 3.0 port. To say our expectations are high would be an understatement.
Asus makes great routers with particularly good on-board software, but if your budget can't stretch to the all-singing RT-AC88U, the firm's slightly older RT-AC68U is still rather nifty.
It's a more traditional 3x3 802.11ac model, but with the same software as used on all other Asus networking kit, which is a very good thing. So many small details are covered, from a notification system to simplified updates, that it puts Asus in front of nearly every other manufacturers by some distance. And with still-excellent wireless performance and range.

8. Synology Router RT1900ac
Speed: 802.11ac: 1300 Mbps, 802.11n: 600 Mbps | Connectivity: 5x Gigabit Ethernet, 1x USB 3.0, 1x USB 2.0 | Features: Synology Router Manager Software | Price: $149.99 (amazon.com)

For technology enthusiasts the name Synology is, aptly, synonymous with Network Attached Storage. The company has offered a string of well-regarded NAS drives for many years. What it’s not known for, however, is routers, but with the RT1900ac it’s clearly looking to change that.
One of the strengths of Synology’s NAS drives has always been its software, so that’s one area that we hope is carried over into this new arena. As its name suggests, the Synology router offers a maximum theoretical throughput of 1900Mb/s – 1300Mb/s at 802.11ac 5GHz, and up to 600MHz at 802.11n 2GHz. Of course, real-world speeds are much lower than this, but for an AC1900 router the Synology is one of the less expensive in its class.
If you've used a Synology NAS, you'll be familiar with the company's Linux-based software interface that presents a Windows-like environment, with icons, folders and so on with all the settings to configure your hardware. Synology has gone with the same software design with the Synology Router Manager on the RT1900ac, its first wireless router.
 Hardware-wise it offers the same sort of thing as other 802.11ac routers, with 1300 Mbps 802.11ac and 600 Mbps 802.11n. Unsurprisingly, there's also great support for shared storage, with well-designed iOS and Android apps to access files. Uniquely, there's also an SD card slot joining the single USB 3 port for shared external storage.

9. TP-Link Archer C9
Speed: 802.11ac: 1300 Mbps, 802.11n: 600 Mbps | Connectivity: 5x Gigabit Ethernet, 1x USB 3.0, 1x USB 2.0  | Price: $119.99 (amazon.com)

The Archer C9 is among the cheapest AC1900 known-brand routers you can buy, undercutting the likes of the Netgear R7000 by some £30 or so. Yet it wants for little when it comes to other extra features, such as USB support for sharing hard drives and printers and four gigabit Ethernet ports.
So if you want to get the up to 1,300Mbit/s wireless speeds of AC1900 but don't want to break the bank, it's well worth a look.
Although the Archer C9 is relatively inexpensive, there's very little lacking from its specification list. It supports 1300Mbps 802.11ac wireless speeds that will deliver maximum performance for just about all laptops currently on the market.
It has good software, powerful internals and a bright white, inoffensive look that won’t look garish in the middle of your living room. Although the built-in modem only supports DSL, rather than VDSL 2, very little else has been left out, making this a solid value option.

10. AVM Fritz!Box 3490
Speed: 802.11ac: 1300 Mbps, 802.11n: 450 Mbps | Connectivity: 4x Gigabit Ethernet, 2x USB 3.0 | Features: VDSL 2 modem | Price: $128.56 (amazon.com)

The new mainstream Fritz!Box 3490 offers the guts of the company's top-end 7490 router, including 3x3 MIMO 802.11ac wireless, but without the built-in hardware to manage DECT or analogue telephony, which brings down the unit's cost considerably.
The 3490 has a built-in a modem that supports ADSL and VDSL with the same vectoring technology that allows for faster fibre connections. Of course, as with just about any other router, it works fine with cable connections too. There are two USB 3.0 ports, one at the side and one at the rear, with four gigabit ethernet ports at the back, along with a DSL connector.
AVM's more high-end 802.11ac routers support built-in VOIP hardware and act as a base station for DECT cordless phones, in addition to router and DSL functions. But the Fritz!Box 3490 leaves all those extras behind in favour of affordability and simplicity.
Sporting an unusual red and silver appearance, the recently updated 6.50 software has some features that more technical users will love. It gives you plenty of control over your home network, such as the ability to scan for local wireless networks that may cause interference, and extensive logging to see exactly how much bandwidth each of your computers is consuming.

Biggest Data Centres

Top 10 Biggest Data Centres in the World 2016
A data centre is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and various security devices. Large data centres are industrial scale operations using as much electricity as a small town.
There are hundreds of data centres spread across the globe. The majority are relatively small, with an average size of around 100,000 sq. ft. But then, there are the big ones which use as much energy as a small city with a couple thousand inhabitants.
Which ones are the biggest? To answer that question, a list of the top 10 biggest data centres by size and capacity given below:

1. Range International Information Group
Location: Langfang, China | Area: 6,300,000 Sq. Ft.


The Chinese economic and technology boom of previous decades is leading the country’s government to invest more on the IT sector. As a result, new data centres are urgently needed. By the time the Range International Information Group data centre is completed, its square footage will be nearly the same size as the Pentagon in Washington and equivalent to nearly 110 football pitches.
Range’s 6.3 million square foot facility is being built in the Hebei province and is expected to be finished next year.

The building will be used as the IT infrastructure platform of Langfang Range Int’l Information Hub in the Hebei Langfang Economic Development Zone.
The venture will help to further develop Langfang City and will be used as a host for smarter transportation, e-government, administration systems, and food and drug safety services.

2. Switch SuperNAP
Location: Nevada, USA | Area: 3,500,000 million Sq. Ft.


Switch is still owner of the world’s largest data centre. Its title will remain untouched until the Chinese Range International Information Hub opens next year.
The base is stratigically located in Las Vegas, southern Nevada, to avoid natural disasters. There are plans for the centre to undergo a major expansion plan across 1,000 acres of land in the Tahoe Reno Industrial Centre at a cost of $1 billion, making Nevada the most digitally connected state in the US.
Switch estimates works to be completed between 2020 and 2025.

The project includes the deployment of 500 miles of fiber optic network cables that will connect Reno, Las Vegas, Los Angeles and San Francisco. Data will travel between Reno and Las Vegas in just 7 milliseconds, giving 50 million people access to data within 14 milliseconds.

3. DuPont Fabros Technology
Location: Virginia, USA | Area: 1,600,000 million Sq. Ft.


Part of a data centre agglomerate made of six buildings, the DuPont Fabros Technology campus boasts a total of 1.6 million sq ft following the opening of the ACC7 facility in September 2014.
With 28 computer rooms and capacity for over 10.5 thousand servers, the ACC7 has 450 thousand sq ft of commercial area and produces 41.6 MW of power.

DuPont built the centre with a medium voltage electrical distribution system and an isolated parallel uninterruptible power supply topology.

4. Utah Data Centre
Location: Utah, USA | Area: 1,500,000 million Sq. Ft.


The Utah Data Centre, officially named the ‘Intelligence Community Comprehensive National Cybersecurity Initiative Data Centre for the US Intelligence Community’, is located at Camp Williams near Bluffdale, 
Utah completed in May 2014, construction costs topped $1.5 billion. At the time of its opening, Forbes estimated the storage capacity to be between three and 12 exabytes, with the possibility of this being extended in the future.
During the construction, the new 65 MW centre made headlines because of the several power surges that brought systems down over 13 months, damaging equipment with costs surpassing the $1m mark.

5. Microsoft Data Centre
Location: Iowa, USA | Area: 1,200,000 Sq. Ft.


Microsoft announced plans in April 2014 to build yet another data centre. The new facility will add 1.2 million sq ft of commercial space to the giant’s portfolio that already grosses 4.1 million sq ft. If all its data centre buildings were put together, Bill Gates’ company would rank first for the largest amount of data centre space with 6.3 million square footage.
The site is located in West Des Moines, Iowa. At a cost of $1.13 billion the new facility will expand servers over one million square feet. The new infrastructure is due to be finished between 2019 and 2021.

In 2008 Microsoft built the first base in the region with a massive expansion at a cost of $677.6 million being carried in 2013. The new stage of construction is part of a $2 billion project named Alluvion.

6. Lakeside Technology Centre
Location: Chicago, USA | Area: 1,100,000 Sq. Ft.


The telecommunications hub is owned by Digital Realty Trust, a Schneiuder Electric customer, and is used by companies like IBM, CenturyLink, Facebook and TelX.
The enormous facility has a backup of 53 generators for any eventuality and utilises 8.5 million gallons of cooling fluid per year.

The industrial building was originally built to house the printing presses for Yellow Book and Sears Catalogues. It now holds fibers and power cabling, and heavy computing equipment, producing hundreds of megawatts of power.

7. Tulip Data Centre
Location: Bangalore, India | Area: 1,000,000 Sq. Ft.


The Tulip Data Centre is currently the largest data centre in the world outside the US.
In 2011, Tulip Telecom announced the construction of that that would become the largest data centre facility in Asia (until 2016).
IBM was chosen by the teleco to assist with design consultancy for the overall data centre space covering a range of data centre technologies, including power, cooling, rack layout, chillers, UPS, DG sets and others. Furthermore, the company helped with turnkey execution to build the first phase of the data centre.

Consultant Schnabel was also chosen to make the company’s project come to light by offering peer review consulting to Tulip.

8. QTS Metro Data Centre
Location: Atlanta, USA | Area: 990,000 Sq. Ft.


The centre was constructed in 1954 as a Sears southeast distribution centre, and today gets power from an 80 MW on-site substation dedicated to the Metro facility.
In 2000 MetroNexus and CoreLocation bought the building and converted it to a telecom and data centre use at a cost of $80 million. Six years later, in October 2006, Quality technology Services bought the 1033 Jefferson Street venue in Atlanta.

The structure is fed by two substations and two electrical grids. An extra 36 generators support 16 independent UPS systems. Over 600 CRAH units (30-ton and 70-ton), provide air flow to raised floor space.

9. Next Generation Data Europe
Location: Wales, UK | Area: 750,000 Sq. Ft.


Completed in 1998, the Next Generation Data Europe data centre in Newport is Europe’s largest data centre facility.
Originally built to host an LG semiconducter plant, BT and Logica are the two main costumers of NGD since 2010, occupying two 75 thousand sq ft halls each.
BT deployed hundreds of server racks in the Welsh data centre, aiming to increase capacity for IT and communications services for its customers in the UK and worldwide.

Logica’s usage of the facility was planned to help manage the IT requirements of its governmental clients.
It’s 19,000 server cabinets plus storage are displaced across three floors with the capability to also host private data centre pods. It also has shell space to accommodate data centre container installations.

10. NAP of the Americas
Location: Miami, USA | Area: 750,000 Sq. Ft.


The NAP of the Americas, a Terremark data centre, was constructed in 2001 as a centralised infrastructure utilised by over 183 networks. It also detains a Tier-III class facility denomination with redundant power and cooling infrastructure.
In 2011, telecoms Verizon bought the facility for $1.4 billion in a bid to accelerate its "everything-as-a-service" cloud computing.
More than 160 global carriers exchange data at the NAP of the Americas. Currently, some companies making use of racks, servers and other services at the central downtown Miami building include NewServices, Voxility, Locaweb and PanamaIT.

To power the station, 12 HiTEC continuous power systems work at full speed providing 10x better transfer rate than typical battery-based UPS. A medium-voltage switchgear is fed by three independent 13,200 volt feeders.

The building was erected outside the FEMA 500-year flood zone and features seven-inch thick steel-reinforced concrete exterior panels.
