Types of Buses in Computer

A computer bus is also known as a local bus, data bus, or address bus, a bus is a link between components or devices linked to a computer.

A bus, for instance, carries data through the motherboard between a CPU (Central Processing Unit) and the system memory.

It is a communication system in computer architecture that transfers data between components inside a computer, or between computers.

The term encompasses all the components related to hardware (wire, optical fiber, etc.) and software, including communication protocol.

(a) System bus – connects the CPU to the motherboard’s main memory. The system bus is also known as a front-side bus, a memory bus, a local bus, or a host bus.

(b) A number of I / O Buses, (I / O is an input/output acronym) connecting various peripheral devices to the CPU. 

These devices connect to the system bus through a ‘bridge’ implemented on the chipset of the processors.

Other I / O bus names include “expansion bus,” “external bus” or “host bus”.    Visit our blog to read more about functions of computer buses and its components.
