the nervous system of the computer
it helps other components adapt to
each other

Video Card

send graphical video display to devices
such as the monitor, projectors and TV's

USB(Universal Serial Bus) Ports

USB ports are ports that
allow other devices to connect
to the computer

Northbridge and Southbridge chips

A Northbridge or host bridge is one of the two chips in the core logic chipset architecture on a PC motherboard, the other being the Southbridge . Southbridge is the chip that controls all of the computers I/O functions, such as USB, audio, serial, the system BIOS, the ISA bus, the interrupt controller and the IDE channels. In other words, all of the functions of a processor except memory, PCI and AGP
