Computer Buses

A computer bus is a communication system within a computer that transfers data between components or devices. A bus is a wire or a set of wires controlled by rules called the protocol.

Buses serve as a central highway, connecting the CPU, memory, storage, and peripherals, allowing them to send and receive data efficiently.

The bus architecture is crucial for coordinating communication and maintaining overall system performance.

Bus speed, often measured in megahertz (MHz) or gigahertz (GHz), determines how quickly data travels, impacting the responsiveness of a computer system. A bus's protocol indicates in which speed data should pass through that bus.

High-speed buses enable faster data exchange, supporting demanding applications and system performance.
