THE BUS

What is a bus??

A bus is a collection of wires which data is transmitted from one part of a computer to another. It is not a point-to-point connection. By the way it can logically connect several peripherals over the same set of wires and each bus defines its set of connectors to physically plug devices, cards or cables together. It connects all the internal components of a computer to the motherboard. It is also known as local bus as it is intended to connect to local devices, not to those in other machines or external to the computer.

Examples of internal computer buses

There are two types of internal computer buses:
Parallel
· Low Pin Count or LPC
· Extended ISA or EISA
· Peripheral Component Interconnect or PCI
· Industry Standard Architecture or ISA

Series
· HyperTransport
· PCI Express or PCIe
· I2C
