Processor (CPU)

What is processor (CPU)? 

Processor (CPU) 

A computer processor is commonly referred to as the CPU, or central processing unit of a computer. The processor is the primary component of a computer designed to move and process data. Computer processors are commonly referred to by the speed that the CPU can process computer instructions per second measured in hertz and are one of the primary selling points of a computer.

Full information of Processor (CPU) 

A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The four primary functions of a processor are fetch, decode, execute and writeback.

 Basic elements of a processor (CPU) 

The arithmetic logic unit (ALU), which carries out arithmetic and logic operations on the operands  in instructions. 

The floating point unit (FPU), also known as a math coprocessor or numeric coprocessor, a specialized coprocessor that manipulates numbers more quickly than the basic microprocessor circuitry can.

Most processors today are multi-core, which means that the IC contains two or more processors for enhanced performance, reduced power consumption and more efficient simultaneous processing of multiple tasks ( parallel) separate processors installed in the same computer, but because the processors are actually plugged into the same socket. 



L1 and L2 cache memory. Their inclusion in the CPU saves time compared to having to get data from random access memory (RAM).

Term processor is 

used interchangeably with the term central processing unit (CPU), although strictly speaking, the CPU is not the only processor in a computer. The GPU  (graphics processing unit) is but the hard drive and other devices within a computer also perform some processing independently. Nevertheless, the term processor is generally understood to mean the CPU.

The processor in a personal computer in small devices is often called a microprocessor. That term simply means that the processor's elements are contained on a single chip that is integrated circuitry (IC)

How Does the Processor Work? 

The computer processor acts as the primary coordinating component of the computer. The CPU will access programs, data, or other computer functions from RAM (Random Access Memory) when called by the computer's operating system. The processor will then interpret the computer instructions that are related to the ordered task before sending it back to the computer's RAM for execution via the computer system bus in the correct order of execution.
