What is the full form of CPU ?

Cpu Description:
CPU full form or meaning is the Central Processing Unit.
CPU stands for Central Processing Unit, which is also called the processor.
the processor or central processing unit is the main part or we can say the brain of a computer, which processes data given by the user and produces an output.
CPU is the component of any computer, which provides the processing power to the computer.
The central processing unit of modern computers works at lightning speed and performs millions of calculations within seconds in order to execute any program.
we often say CPU as the brain of the computer, because this is the place where all the arithmetic calculations and logical operations take place.
the CPU handles and executes all the instructions received from various application software running on that computer and also from the hardware component of that computer.
The first CPU was invented by Federico Faggin an Italian Scientist in 1971, named Intel 4004.
A Microprocessor or Central Processing Unit is made up of IC or Integrated Circuit Chip.
The CPU consists of millions of IC chips, packed inside a single processing chip. and each of these Integrated Circuit Chips is made up of millions of nano components, called transistors.
these transistors inside integrated chips are made of a semiconductor material Silicon.
these transistors are the basic building blocks of a processor and functions as a micro switch, which can be programmed for two states, either on or off.
and this is the main reason, a computer or processor understands only binary language or binary code, which is 0 and 1, represents off and on.
The CPU has internally three Main Units-
All central processing unit internally implements an Architecture and also supports a predefined command. This set of commands to the processor is called an instruction set of CPU.
The work of any CPU is to execute many types of instructions stored on any computer, which is called a program.
so during the execution of any program CPU follows a certain predefined cycle.
the Central Processing Unit instructions cycle is executed sequentially
