Microsoft’s Surface 3 is the first announced device to use Intel’s new Cherry Trail Atom chips, but you can expect therm to show up soon in other devices too. So what are the chips capable of and what should we expect? The Surface 3, which  went on sale Tuesday , highlights some of the capabilities of Cherry Trail, officially called the Atom X5 and X7. The chips can run full Windows 8 and Windows 10 and are better at graphics than their ‘Bay Trail’ predecessors. But they also have limitations. They won’t do so well at compute intensive tasks such as video editing, which remain the domain of Intel’s faster Core processors. Here’s a few other things to expect: Multiple OSes Cherry Trail tablets will run both Windows and Android—though don’t expect too many of the latter. Atom chips are favored more in Windows tablets, which is partly why Intel is struggling to compete with ARM, which dominates the huge Android market. Cherry Trail chips will initially go into higher-end...

In the present world one of the hottest topic in the industry is VoLTE. So let us see briefly about the technology to understand how this works. Since the launch of  Jio , one of the technical jargon’s that is widely in buzz is  VoLTE  and Reliance Jio is also betting big on  VoLTE. Being a highly technical terminology there have been many doubts arising on  VoLTE.  We have tried to clear all those doubts/confusions with this article. I will also try to explain VoLTE in a very simple terminology without going much into technical details and keep it as short as possible. × While I will not consider all the aspects/implications of technologies, I will explain mainly about VoLTE in a consumer centric approach. *The disadvantages of any technology discussed here is out of the scope of this article. Voice/Data implementations in India : 1. GSM/G/GPRS :   Voice call  without  simultaneous data transfer support 2. EDGE/E : a) Voice ...

That's a good question. Goblin's answer is a good analogy but a little bit scant on details. It's fairly entertaining too. I like his post. I'll see if I can be more succinct in simple terms. CDAF focuses directly on the sensor. It uses a distinct lline in the image by moving the lens until that line obtains the highest contrast, which coincides with the sharpest focus. It works best with lenses designed to move with these focus motions. It does not work well with the Olympus E-series DSLR, 4/3 lenses. CDAF has in the past been used primarily on P&S cameras and is now used on micro 4/3 cameras like the OM-D E-M5 and E-P5. It works well on Pen and OM-D cameras when micro4/3 lenses are used but works very slowly with Olympus's 4/3 lenses built for DSLRs. PDAF uses a sensor placed in the light path created by the mirror. It works basically the same way with any DSLR, or single lens reflex camera, like the E-5. It uses two sensor points to detect...
