Computer System Bus Architecture

System Bus Architecture: 

The system buses connect the different component such as the CPU, system memory, and all other components on the motherboard.

System Bus can be classified into three types, as:

• Data Bus.
• Address Bus and
• Control Bus.

• Data Bus: A kind of system bus that carries only data from system components to the memory and from the memory to the system components is called data bus. It directional. It may be 8 bit, 16 bit, 32 bit and 64 bit. It means, it can carry up to 2n bit.
• Control Bus: A kind of system bus which carries control signal from the processor to other devices is called control bus. It is also directional. It connects all the devices with processor.
