The document explains the Central Processing Unit (CPU), describing it as the brain of a computer that processes all operations. It details its connection to the motherboard and components like RAM and USB ports, along with its basic functions of receiving, processing, and outputting data. Additionally, it outlines the roles of the memory unit and the arithmetic logic unit (ALU), as well as mentions popular CPU brands like Intel and AMD.

2. What is CPU?
 A processor or microprocessor is a
small chip that resides in
computers.
 Central Processing Unit.
 CPU is the brain and heart of a
computer.
 Every operation done with the
computer is processed by the
CPU.

3. Processor on mother board
The CPU fits into the motherboard
The motherboard serves as a base connecting all the
components of the computer
On the corner of the motherboard, there is a memory
slot

4. The RAM chip fits into the memory slot
RAM is short for Random Access Memory
RAM holds all the data that is being processed by the
CPU

5. On the left of the motherboard, there are USB ports
USB is short for Universal Serial Bus
The input and output devices can plug into the USB
ports using USB cables

6. A processor performs three basic functions
Receive input data
Process data
Output data

7. Processor Components

8. Memory Unit
• The memory unit supplies information to other units
of the computer when needed
• This unit stores all the data and the instructions
required for processing
• It stores intermediate and final results of
processing
• It stores data temporarily or permanently

9. Control Unit
The control unit acts like a supervisor
It controls the operation of all parts of the computer

10. Arithmetic Logic Unit (ALU)
1.The ALU is the heart of the CPU.
2. It performs various arithmetic and logical
operations on the data provided
The popular brands of processors are
Intel and AMD.
The processors are rated depending
on their price, power and
performance
