What is "Bus"?

[KennyS]

Hello

I'am a computer hardware architecture beginner,
i'd like to know what is it meant by "local bus",

which i always encounter, and what is the difference between "local bus" , "address bus" and "data bus"?

I wish someone could help me with the question~

Definitions of Computer bus on the Web:

In computer architecture, a bus is a subsystem that transfers data or power between computer components inside a computer or between computers. Unlike a point-to-point connection, a bus can logically connect several peripherals over the same set of wires. Each bus defines its set of connectors to physically plug devices, cards or cables together.
