What is Computer? | Computer Science Quiz: In the modern world, computers of all shapes and sizes are all around us. With a mouse click, we can utilize them to send or receive data from anywhere in the world. Today, we may use our computers to send emails, watch television, play games, work on business data, listen to music, view video lectures, and perform a plethora of other tasks. Today’s computers come in a variety of sizes and designs, including desktop, palmtop, laptop, PDA, and more.    

What is Computer?

A computer accepts information (in the form of digitalized data) and manipulates it in accordance with a program or set of instructions that specify how the information should be processed. The person who enters the data into the computer to produce the desired outcome is known as a programmer.

Our lives now revolve mostly around computers. You can use a computer to find out information on the booking of tickets (for aircraft, trains, and movie theatres), a person’s medical history, books in a library, a location on a map, or the definition of a word. You might be shown the information in the form of pictures, text, video, etc.

Benefits of Computer

There are many benefits of computer which are mentioned below:

Benefits of Computer Science Degree (Education)

Medical surgeons can also get help from computers during complicated surgical procedures like laparoscopic procedures, etc.

Engineering and Science

Computers are used by scientists and engineers to execute difficult scientific calculations, to design and create drawings (CAD/CAM programs), as well as to simulate and test designs. Computers are used to visualize three-dimensional objects, store complicated data, and execute sophisticated calculations. Without computers, intricate scientific applications such as space exploration, rocket launch, etc. would not be possible.


Computers are used by the government for both e-governance and the management of internal operations. Users can get information on the websites of the various government agencies. Computers are utilized to pay taxes, file tax returns, submit online water and power bills, access land record information, and more. Computers are used by the police department to look for criminals using fingerprint matching and other methods.
