description of the raid
in this article I will explain about the notion raid
"Various kinds of methods are used to enhance performance and also reliability of the disk. Usually to improve performance, involved a lot of disks as one storage unit. Of each block of data is broken down into sub-blocks bebarapa, and is divided into the disks (striping) . when sending data disks work in parallel, thus increasing the transfer speed in reading or writing data. coupled with the synchronization of the rotation of each disk, then the performance of the disk can be improved. this way is known as RAID - Array of Independent Redudant (or Inexpensive) Disks. other than RAID performance problems can also increase the reliability of the disk by using an additional disk (redudant) to store the parity bits / block or as a disk-disk mirror from existing data.

Command Prompt
Command Prompt or we often call the CMD, is an innate program Windows Operating System that is similar to MS DOS "Microsoft Disk Operating System." CMD in the text-based operation, where a user must type the commands one by one, which can be understood and then processed and displayed. This makes CMD different programs based GUI. We as users need to know the command or commands that are recognized by the CMD, for which there are a few basic commands we will learn:
The most important thing in using the CMD is the placement location. When the CMD will be opened by default in c: \ Documents and Settings \ Mr.DIAS> ", which should I do if for example I want to go into a folder on drive D is that I should switch to the drive with the command D: like The following "C: \ Documents and Settings \ Mr.DIAS> D:" then the D:> CD Folder Name to go to the folder I want and if I wanted to get back I'll have to type the CD .. to go back one stage. CMD also we can use to open programs or files that we want, for example I wanted to open the MS Word program "D:> START WINWORD" about the place where the current drive is not a problem, we can open any application even though we are in the drive D by knowing the name used by the application, different if we want to open a file because we have to inform the CMD location of the file, for example I want to open a file on drive E with 1.doc PRACTICE filename, then I'll have to type " D:> START E: Exercise 1.doc "so CMD will know where to position the file is located. Please note, not all programs can be opened using the CMD. Download Command Prompt Basic Command

How To Install Ubuntu Operating System
Ubuntu (Linux) may still was a stranger to some people, but now many people / communities who are already using ubuntu as a primary operating system in its computer or notebook.
Most people are just trying Ubuntu are still experiencing difficulties during the installation process. Here I will try to give the steps to install Ubuntu on the desktop or your notebook. Click the link below to download "how to install ubuntu".

Comparison a reference video card and the factory-overclocked !
compare a reference ATI Radeon HD 5870 card and the factory-overclocked MSI R5870 Lightning TwinFrozr II, analyzing real-world differences between the two. We'll also run the reference card at overclocked settings as well, because we wanted to see if the pricier aftermarket solution can deliver more value than a reference board tuned to run faster.
The baseline for this article is AMD’s Radeon HD 5870, which we're running at its default clock speeds and a maximum overclock without leaning on voltage tweaks. We did the same with MSI’s R5870 Lightning, using the factory-overclocked speed default instead of the AMD reference spec. Then we add another test run at the card's fastest stable overclock, again without modifying voltages. Read More
