Computer Components Explained
What A Computer CPU Is And Does
The computer CPU (Central Processing Unit) is the part of the machine that makes the computer function, basically. It is responsible for carrying out the instructions of a program, which is done by accessing information from the memory and performing some specific action with it. After performing this action, it performs a 'writeback', wherein the changed information is re-written onto the memory.
What A Computer Motherboard Is And DoesMany people have heard the term computer motherboard, but are unsure what it is. This printed circuit board is also known as a system board or the mainboard. This board holds many vital components for today's modern PCs, and it also provides connections for peripherals. Peripherals include the microprocessor, memory, cooling fans, CD and DVD drives. Here is information to provide a little better understanding for this important hardware.
What Computer Memory Is And Does
When using the term computer memory people are normally referring to any device used by or on a computer to keep programs or data stored for any period of time. DDR is double data rate memory. Basically this makes the ability for higher transfer rates because it makes use of stricter control over the timing of the electrical data and the clocks signals. Of course DDR-2 replaced DDR although if your motherboard is equipped for DDR-1 you will not be able to make DDR-2 function.
What A Computer Video Card Is And Does

video adaptors are sometimes called video chips, display adapters,
graphics cards, video cards or graphics accelerator cards. The CPU, or
Central Processing Unit, of a computer picks up the data from various
files and sends that data to the card to process it and return the
desired clip. Powerful on board memory and processors help to free up resources normally provided by the main system CPU, thus speeding up the system overall. Instead of requesting Memory and Processing power from the main CPU, it is able to carry out the majority of the load.
What A Computer Sound Card Is And Does
One of the most important parts of a computer if you love video games and entertainment is the sound card, which is sometimes also called the audio card. This is an internal computer expansion that helps amplify and facilitate the audio signals coming from computer programs. It typically attaches to the motherboard through a wide variety of hook ups.
What A Computer Case Is And Does
Computers come in many shapes and forms and have many things in common. One thing that all computers have in common is the computer case. Computer cases are hard structures which encase the outside of a unit. Depending on the kind of computer a person buys there may be quite a large difference in the style of case that it has.

What A Computer Hard Drive Is And Does
A computer hard drive is responsible for the storage of
non-volatile data. Non-Volatile refers
to the hard drives ability to store Operating System files, program files, game
files, and data files without the need for power. When you turn off your computer, the hard
drive retains the information, or data.
