What is The Purpose of The Computer's Specs

In buying a computer we need to know about the components in the computer. In any computer, usually consists of mainboard / motherboard, processor, RAM, VGA, hard disk, monitor, and others. Here is an explanation of these components:
1. Mainboard / motherboardMainboard / motherboard is the central controller that regulates the work of all components installed on the motherboard. Manage the motherboard alsoelectrical power on any PC component. All data traffic is regulated by the motherboard, from the storage device (hard drive, CD-ROM), a data input device (keyboard, mouse, scanner), or a printer to print.

Overclocking fever also contribute a role in the development of the world's motherboard.
The motherboard manufacturer motherboard race the race issue is designed to provide a high level of overclocking, but still able to maintain system stability. If there was a motherboard that can not be used to overclock the processor and memory, then almost certainly the motherboard is less sold on the market.
2. ProcessorProcessor is a major part of the computer. The function of this component is to organize all the running processes that occur during computer work. Therefore, the greater the processor speed, the faster execution of programs on the computer. Units for Mhz processor itself is (mega hertz) or GHz (Giga Hertz).
Units for Mhz processor itself is (mega hertz) or GHz (Giga Hertz).
A processor consists of an ALU (Aritmatic Logic Unit), the logic unit is constructed from logic gates (AND, OR, NOT, EXOR, etc.). Also equipped with UC (Control Unit)who had other periperial control functions. Processor speed is determined by processor speed, cache memory, and FSB (Front Side Bus) which is usually written on the backprocessor. In the placement (installation) processor was placed in a place called socket, socket itself can indicate the type / model / brand of processor.
3. RAM (Random Access Memory)Ram is a type of computer storage whose contents can be accessed in any order that the data is in memory. This is in contrast to sequential memory devices such as magnetic tape, disk and drum, in which the mechanical movement of the media storing force the computer to access data sequentially. Usually the RAM can be written and read, as opposed to-read-only memory (read-only-memory, ROM), RAM is usually used for primary storage (main memory) in computers to use and modify information actively, although some tools use some type of RAM to provide long-term secondary storage. But there is also the opinion that the ROM is another type of RAM, because it is also true random access as well as SRAM or DRAM. It's just really the process of writing the ROM requires a special process is not as easy and flexible as well as the SRAM or DRAM. In addition, some parts of addres space of RAM (main memory) of a system that is mapped into one or two-chip ROM. Here are some types of RAM

4. VGA (Video Graphics Adaptor)VGA is a component that serves to convert the digital signal from the computer to display graphics on the screen. VGA Card sometimes called Card displays, VGA cardor the graphics card. Points of attachment of the graphics card called the expansion slot. VGA card (Video Graphics Adapter) allows you to translate the output (output) to a computer monitor. Todrawing / graphic design or for playing games.



5. Hardiskstorage media of the Operating System of your computer. Such as Windows or Linux. Its main function as a storage medium or storage of data permanently. Hard disks store all kinds of information, one of which information about the hardware in the PC, and the OS itself. Hard disk is one of the components that determine the performance of your PC. The faster the hard disk to work, the sooner the resulting transfer.
