What is Computer? | Characteristics and Components of Computer

1. Speed:

Working on computer is extremely speedy. Billions of calculations are executed within seconds via computer. Computer speed is calculated in MegaHertz and Giga Hertz. The computer workings are quicker than human beings. The computer does a batch of computations in a second and humans complete any computation over one minute.

The mouse is not often broken or fails. LCD is not often broken or fails.

3. Accuracy:

Assume we desire to get average marks of complete students in class. A mistake is possible when it is performed by a human being. There is no possibility of error if this work is performed by a computer.

5. Flexibility:

We can use the computer for playing games, listen to music, watch movies, etc.

6. Constancy: 7. Communication:

All computers these days can converse with other computers. We can attach two or more computers by a communication gadget such as a modem. The linked computers are called networks.

What are computer hardware and software?

Components of Computer:

Special parts of a computer system are as follows:

The data entering or given to the computer by using components of computer is called input. There are many components of computer that are used to enter data into computers and these components of computer are called input devices. Mainly used input devices are keyboard, mouse, microphone, scanner, digital camera as well as PC camera.

The data converted into useful information is called output. The components of computer used to show information to the consumer are called output devices. Mainly normally used output devices are Monitor, Printer, and speaker.

A box that contains different electronic components of computer that are used to process data is called a system unit. Every computer system must contain a system unit.

The computer cannot work without a system unit. In components of computer system unit is most important components of the computer.

The system unit is the main or important component of the computer system. All components like (RAM, Processor, etc) in the system unit are attached to the motherboard. The motherboard is also identified as a system board or mainboard. The System board is the contact medium for the whole computer system.

Physical parts of the computer that are used to store data for later use are called storage devices. It is called nonvolatile for the reason that its files and other data stay protected or safe when the computer is turned off.
