BRAIN OF COMPUTER
The Central Processing Unit is the brain of the computer.
It control and process all the information in the computer.
![Page 8: CPU and its components](https://reader035.fdocuments.net/reader035/viewer/2022062503/58ed8b491a28ab1f0a8b45fd/html5/thumbnails/8.jpg)
CPU is housed on a single chip called microprocessor.
It is located in system unit.

COMPONENTS OF CPU• The CPU has three components .
1. ALU(Arithmetic Logic Unit): Performs all arithmetical calculations such as addition and multiplication & makes all logical decisions.
2. CU(Control Unit): Directs different parts of the computer to carry out instructions. It controls communication and coordination between input/output devices.
3. MU(Memory Unit): Stores data & instructions to process data

• Attached to the CPU.
• They are storage devices.
• They are housed within the computer or
in an external box.

Hard disk drive(HDD)
• Made up of several disks.
• The disks are sealed in an airtight case
to protect it from dust.
• Each disk store data.

USB port
• USB port is a part of system unit and is
linked to CPU.
• We can attach input/output devices and
USB flash drive to the USB port.
