A CPU is called Central Processing Unit . It is also called as central process / processor.
A processor is the electronic circuitry within a computer that executes instructions that make up a computer program.
The CPU performs basic arithmetic logic , controlling input /output (I/O) operations specified by the Instructions in the program.
The computer industry used the term ” central processing unit” as early as 1955.
Principal component of a CPU include the arithmetic Logic Unit (ALU) that performs arithmetic and login unit.
One or more CPU’s implemented a single metal-oxide – semiconductor (MOS) IC chip. Microprocessor chips with multiple CPU ‘s are Multi Core Processor.
The individual physical CPU’s processor cores , can also be Multi treated to create additional virtual or logic CPU’s.
