The Central Processing Unit (CPU) is the brain of the computer. It follows instructions,
solves problems and runs programs. It is a small chip placed inside the CPU box/

cabinet.

Parts of the CPU

The CPU has the following main parts:

1. Control Unit (CU): The Control CPU
Unit tells the computer's memory, Control Unit

arithmetic/logic unit and input/
output devices how to respond to

the instructions it receives. Arithmetic
Input Logic Unit Output
2. Arithmetic Logic Unit (ALU): The

Arithmetic Logic Unit is the part of
the CPU that does mathematical Memory Unit

calculations and logical tasks.

3. Memory Unit (MU): The memory unit stores data and instructions.

OUTPUT DEVICES

Output devices are hardware that
display the results of your work. These The speed of a CPU is measured in Gigahertz

devices display or print data processed (GHz), ranging from 2.0 GHz to 5.0 GHz.
by the computer. Let us learn about some of them.

Monitor

The monitor, also known as a display screen or Visual Display Unit (VDU), shows

output, such as text, images and videos. Some common types of monitors are
Cathode Ray Tube (CRT) monitor, Liquid Crystal Display (LCD) monitor and Light
