Simple Explanation

A shared electrical pathway that carries data or power between parts of a system.

Concise Technical Definition

A set of one or more electrical conductors that transmit data, signals, or power from one or more sources to one or more destinations within a system.

Layman-Friendly Analogy

Like a school bus that picks up and drops off kids at different stops, a bus moves signals between components in a circuit.

Industry Usage Summary

Common in computing, audio routing, and electronics—buses are used to link components such as CPUs, memory, mixers, amplifiers, or interface modules, enabling them to share signals or power along a common path.

Engineering Shortcut

Bus = Shared signal/power path between multiple devices.

Full Technical Explanation

A bus in electrical and digital systems is a communication pathway that allows multiple components to share the same signal lines. It can carry data, address, or control signals. Buses are essential for system integration and scaling.
