1 - About
Bus are interface built upon channel decice made of electrical wires for sending raw bits between the components of a computer.
Bus is a subsystem that transfers data between:
- or between computers.
Physically, buses are just electrical wires that connect all components together and each wire transfer a single bit.

Check the Von Neumann organization as most of the computers are based on it. The different type of bus and their function are described in the computer organization design.

3.2 - Width
The size, width of a bus can be:
- one byte
Physically, the total number of wires is called bus width, and is dependent on how many wires a CPU can support. If a CPU can only accept 16 bits at a time, then the bus has 16 wires connecting from a component to the CPU, which means the CPU can only retrieve 16 bits of data a time.
