What is cpu meaning?

CPU stands for Central Processing Unit. It is a key component of a computer system that performs all the processing tasks and operations. A CPU is often referred to as the brain of a computer as it controls and executes all the instructions. It comprises two main components - the control unit (CU) and the arithmetic logic unit (ALU). The control unit fetches instructions from memory, decodes them, and directs the ALU to perform the required operations. The ALU is responsible for carrying out mathematical and logical operations on data. CPUs come in different types and speeds and are measured in gigahertz (GHz). They can have multiple cores to perform multiple tasks simultaneously and cache memory to store frequently accessed data. The CPU's performance plays a crucial role in the overall speed and function of a computer system.
