Know the Dual-Core Processors in Mobile Devices

Dual core processors in early 2011 echoed this. Many smart phones and tablets start to use it as Optmus 2X LG, Motorola Atrix, and tablets Motorola Xoom. Actually, whether it is dual-core? How important is its function? Let's see.

Is it a dual-core processors?

All smart phones and tablets will have a processor, some call it the CPU. Like the brain, the processor functions to manage the data path, so that handsets can run a particular performance. For example, if an application to perform, play games, image processing and so forth.

Each processor itself has a chip. For example, the famous single-core processor Qualcomm and Samsung Snapdragon QSD8250 Hummingbird has a 1GHz chip speed on a single die (board).

Well, for dual-core processors are two chips (including caches and cache controllers) in units of the die. Thus the so-called 'dual'.


What Point?

In terms of processor performance, I had
analogy as a carriage pulled by two horses that run fast. Of course much faster than a horse is not it? Unfortunately the burden of horses right and left sometimes not the same as in attracting the train. This happens for some applications that do not support dual-core processors.

Having a dual-core processors in mobile (tablet or smartphone) means giving freedom to the OS to manage intensive tasks in parallel. Yes, this means more devices can do multi-tasking process better.


Why Dual-Core Better than Single-Core?

Obviously. Because the single-core processors can not perform like a parallel process of dual-core processors. Why? It was easy, because there is only one chip, the processor can only do one-time order information (known as the 'thread') at a time. While dual-core, on the other side can do this simultaneously because the two chips supported.


Fortunately What?

The main advantage if the vendor uses a dual-core processor is the capability of their handsets more quickly and can do multi-tasking process more efficient. The reason is because it supported the two cores that process two threads at once simultaneously.

For users, of their handsets so much running and not feel 'slow' when hitting heavy applications. Well, in 2011, many vendors are beginning to use tablet. Predictably, the first time out on the market price must be relatively high.

Want to have a tablet is much faster than the Samsung Galaxy tab, Dell Streak, or iPad? Just be patient, wait for the presence of new tablets with dual-core processor in 2011 - while waiting for the single-core tablet down prices

Microsoft Warns New Cracks in Windows

Gap had actually already been disclosed to the internet security conference title in North Korea December 15, 2010. But after a lot of applications that can exploit the bug, Microsoft has noticed recently.

While waiting the latest patch released, Microsoft recommends users to narrow down the activity on file shimgvw.dll, ie the component whose task is to create a thumbnail image.
