CPU stands for central processing unit.The CPU does all the thinking that carries out the method for the computer so if there is a virus it notifies you

CPU fan (cooler)

A CPU fan is made to disperse the excess of heat it produces.


RAM stands for random access memory.The RAM is a hardware device that allows information to be stored.


The northbridge is an integrated circuit responsible for communications between the CPU interface,AGP, and the memory.


The southbridge is an IC on the motherboard responsible for the hard drive controller and integrated hardware. Integrated hardware can include the sound card and video card if on the motherboard, USB and Ethernet.

VGA port

Short for Video Graphics Array, VGA provides 640 x 480 resolution color display screens and can display 16 colours at once.

DVI port

Short for Digital Visual Interface, DVI was developed for transmitting digital video content.DVI can even be used with some TVs, although HDMI is more common.
