A computer is organized into three basic units :

1. The Central Processing Units (CPU)
2. The Memory Unit
3. The Input / Output Unit

 

CPU: The CPU is the part of the computer that performs the main function of information processing. The memory units stored data The computer supplies processed information back to the users using special output devices. In a short word, it is called the brain of the computer.
It makes them all the required calculations and processes data.

The CPU can be divided into three main components :

a. ALU

b. CU

c. Registers

ALU (The Arithmetic and Logic Unit): ALU performs all the mathematical and logical operations on the information supplied to the CPU.

CU (Control Unit): This unit directs the working of the CPU. It fetches instructions from the memory and according to the instructions, controls the flow of data between the ALU and other parts of the computer.

Registers: Registers are the storage locations that instructions or data while the CPU is using them. The registers consist of flip-flops and the registers used by the CPU are the latest memory elements in the computer. In contrast, the memory units hold instructions and data before or after the CPU processes these.

CLOCK SPEED: The speed of CPU is known as Clock Speed. A large number of ticks per second the faster is the speed of the CPU. The ticks per second of the internal clock are measured in Megahertz and Gigahertz.
Hertz is the unit of frequency. 1 MHz = 1 million ticks per second, 1GHz = 1000 MHz
So, higher the clock – speed, faster the computer.
