A processor is the logic circuitry that reacts to and processes the fundamental instructions that drive a PC. The four essential elements of a processor are fetch ,interpret, execute and writeback.

The essential components of a processor: 


The arithmetic logic unit (ALU), which completes arithmetic and logic operations on the operands in guidelines.

The floating point unit (FPU), otherwise called a math coprocessor or numeric coprocessor, a particular coprocessor that manipulates numbers more quickly than the essential microprocessor circuitry can.

Registers, which hold instructions and other information. Registers supply operands to the ALU and store the results of activities.

L1 and L2 cache memory. Their inclusion in the CPU spares time compared to getting information from random access memory (RAM).

Most processors today are multi-core, which implies that the IC contains at least two processors for enhanced performance, reduced power consumption and more efficient simultaneous processing of multiple assignments (see: parallel processing). Multi-core set-ups are like having multiple, different processors installed in a similar PC, but since the processors are actually plugged into a similar socket, the connection between them is quicker.

The term processor is utilized interchangeably with the term central processing unit (CPU), although entirely, the CPU isn't the main processor in a PC. The GPU (graphics processing unit) is the most notable model yet the hard drive and different devices inside a PC additionally perform some processing autonomously. All things considered, the term processor is for the most part understood to mean the CPU.

The processor in a PC or embedded in little devices is regularly called a microprocessor. That term just implies that the processor's components are contained on a solitary integrated circuitry (IC) chip.

The two primary competitors in the processor market are Intel and AMD.
