CPU

CPU stands for Central Processing Unit. It is the primary component of a computer that performs the majority of the processing tasks. The CPU is often referred to as the "brain" of the computer because it is responsible for executing instructions and controlling the operations of other components of the system. 

The CPU is made up of several key components, including the control unit, arithmetic logic unit, and registers. The control unit is responsible for fetching instructions from memory and decoding them into a form that the CPU can understand. The arithmetic logic unit performs arithmetic and logical operations on data, such as addition, subtraction, multiplication, and comparison. Registers are small, high-speed memory units within the CPU that hold data that the CPU is currently processing.

The speed and performance of a CPU are measured in terms of clock speed, which is measured in gigahertz (GHz). A higher clock speed indicates that the CPU can perform more instructions per second, which results in faster processing times. 

The CPU is an essential component of every computer system, from small embedded devices to large servers. It works in conjunction with other components, such as RAM, hard drives, and input/output devices, to process data and perform tasks that enable the computer to function.
