The CPU, or Central Processing Unit, is a small silicon chip which runs the whole computer. It is also known as a microprocessor or processor, this terminology has been around since the 60s. It is the heart of your computer and is located on the motherboard as an integrated circuit containing millions of transistors and other electrical components. .

It is made up of various parts, the Control Unit supervises the operation, fetching software instructions from memory and coordinating the order these instructions are carried out. The Instruction Decoder deciphers the instructions it receives from the operating system and application software and performs various calculations, comparisons and computations in its Arithmetic/Logic Unit (ALU). The ALU can perform addition, subtraction, division and multiplication as well as comparing greater-than, less-than or equal-to conditions.

The processor has a Program Counter which tracks new tasks as they are picked up, although certain instructions can cause the CPU to execute jobs out of sequence.

Inside the CPU are Registers, which are special storage locations. The data they contain can be accessed much quicker than other memory; they either store the computer's current instruction or in the ALU, the accumulators store the results of operations being calculated.

Finally, the Processor has a clock which acts as a heartbeat, releasing an electrical pulse at regular intervals, it is by this that we measure the speed measured in MHz. The function of the processor parts together is made up of four repetitive steps which are known as the Machine Cycle. The Control Unit fetches data and instructions from the memory and deciphers the code, then the ALU executes any calculation and finally stores the result in memory.

Inside the CPU the main parts are ------ 1-Mother board On which all the other devices will get connected . In latest Mother board Display card , sound card , lan card , modem are in built, It ha s various port like VGA ports to connect monitor, USB port to connect all USB devices , parallel port to connect printer, 2. Power Supply which supplies the power to all parts of the copmuter . 3. RAM - random acess Memory it works as dinning table for the computer . Processor surves all the results on RAM. 4. Processor which actully does all the work . 5. Hard disk which act as a storage device . All system files, OS , and other software are installed on Hard disk .

. RAM   it is the main memory.
2. Hard-disk   it is the storage required by the computer
3. Motherboard including processor:  It evolves all the jobs or processes in the computer.
4. Different buses and wire lines for communication between all the devices.
5. Drives and input pins .

The CPU has two parts which is the: 1) Central Unit (CU) - it tells the rest of the computer system how to carry out a program's instructions.

2) Arithmetic and Logic Unit (ALU) - it performs arithmetic operations and logic operations and control and speed of those operations.

RaM-when light goes off information is lost.
ROM-it is permanent storage memory. It is used only for cannot bring changes to it .
Motherboard-it contains all the chips of c.p.you which are useful for the computer.
