Processor: The term processor has generally replaced the term Central processing unit or CPU. It is the logic circuitry that responds to and processes the basic instructions of a computer. Mention that it is considered as brain of central component of the PC.

Motherboard: It is the main printed circuit board in a computer. It contains the CPU, appropriate support chips, device controllers, memory and all expansion slots. That connect and communicates all the device and components which are attached.

BUS:BUS is collection of wires through which is used to transmitted address, data and signal from one part of a computer to another part.

Type of BUS:

1) System BUS- e.g. – Address BUS, Data BUS.

2) External BUS- e.g. – ATA, USB, SCSI etc.

CPU: The ALU and CU of a computer system are jointly known as the central processing unit. You may call CPU as the brain of any computer system. It is just like brain that takes all major decisions, makes all sorts of collections and directs different parts of the computer functions by activating and controlling the operations.
