Question

explain CPU and its components?

Answer 1

CPU stands for Central processing unit.It is also known as microprocessor or processor.

The CPU has two components: Control Unit: extracts instructions from memory and decodes and executes them. Arithmetic Logic Unit (ALU): handles arithmetic and logical operations.

Answer 2

CPU stands for Central processing unit.It is also known as microprocessor or processor.A CPU is brain of a computer.It is responsible for all functions and processes.Regarding computing power,the CPU is the most important element of a computer system.The CPU is consisted of thin layers of thousands of transistors.Each transistor receives a set of inputs and produces output.Transistors hold a key role in functioning of CPU as they make computer able to count and perform logical operations which is called processing.It processes the instructions that it collects by decoding the code in programs.Computers use two types of storage: Primary storage and secondary storage. The CPU mainly interacts with primary storage or main memory,referring to it for both instructions and data.


Components of a CPU
The two typical components of a CPU include the following:

The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
