# Computer - Bus

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:

Physically, buses are just electrical wires that connect all components together and each wire transfer a single bit.

## 3 - Property

### 3.1 - Type

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.

##### 3.1..1 - Main

Connection of computer processors

### 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.
