It's a centre processing unit,..

A central processing unit (CPU), also called a central processor or main processor, is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions

Acentral processing unit(CPU), also called acentral processorormain processor, is theelectronic circuitrywithin acomputerthat carries out theinstructionsof acomputer programby performing the basicarithmetic, logic, controlling, andinput/output(I/O) operations specified by the instructions. The computer industry has used the term "central processing unit" at least since the early 1960s.[1]Traditionally, the term "CPU" refers to aprocessor, more specifically to its processing unit andcontrol unit(CU), distinguishing these core elements of a computer from external components such asmain memoryandI/Ocircuitry.[2]The form,design, and implementation of CPUs have changed over the course of their history, but their fundamental operation remains almost unchanged. Principal components of a CPU include thearithmetic logic unit(ALU) that performs arithmetic andlogic operations,processor registersthat supplyoperandsto the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory) and execution of instructions by directing the coordinated operations of the ALU, registers and other components.

Integrated circuits are now used to implement all CPUs, except for a few machines designed to withstand large electromagnetic pulses, say from a nuclear weapon.
