THE MAIN PARTS OF THE COMPUTER

Computer is a multifuctional machine so it works with the support of it's many supporting parts. These parts work together but all have the different kind of works. So the main parts of computer are given below,

1. Central processing unit(CPU)

2. Monitor

3. Hard disk

4. Motherboard

5. Memory of computer

6. Keyboard

7. Mouse

Central processing unit(CPU): - CPU is also known as computer processor which is a electric circuit and executes computer programs. The main responsibility of this CPU is to execute a sequential set of instructions that constitute a program. During the CPU operation there occurs mainly four steps, they are fetch, decode, execute and writeback in which all the operation is performed.

Monitor: - It is a visual display unit. It is most-used output device of computer. The monitors are available with CRT technology, LCD and plasma screens.

Mother board: - A computer motherboard consists of sockets in which microprocessors are instelled, memory slots, a chipset that acts as an interface beteween the CPU bus and the peripheral buses non volatile memory chips housing the system's firmware and clock generator, which helps in the synchronization of various system components.

Memory of computer: - The parts which can achieve efficient storage of large volumes of data are memories of computer. They are also called the primary storer so they are used as primary storage. RAM is a form of computer memory.

Keyboard: - Keyboard is like as typewriter which is a output device of computer. Keys or the buttons are the electronic switches which can take command by pressing them.

Mouse: - Mouse is also known as a pointer which is used to point out the needed sesson in two dimensions. It changes or translates our hand (where we want to click) into signals to which computer can easily recognize and respond what we want to do.
