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

RAM

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

Northbridge

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

Southbridge

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.
