Fields in Computer Science

Computer science is the study of the theoretical foundations of information and computation, and of practical techniques for their implementation and application in computer systems. It is frequently described as the systematic study of algorithmic processes that create, describe and transform information. According to Peter J. Denning, the fundamental question underlying computer science is, "What can be (efficiently) automated?" Computer science has many sub-fields; some, such as computer graphics, emphasize the computation of specific results, while others, such as computational complexity theory, study the properties of computational problems. Still others focus on the challenges in implementing computations.

What Is The Importance Of Computers In Our Daily Lives?

Computers today are one of the important things we are using. They have helped a lot in compiling a lot data which used to be in hard records. One of the uses or benefits of computers is that they are able to provide and retrieve information so quickly so they have increased the pace of our work. The increase in the speed of work has helped us to do many things with less resources like in past a lot of manpower was used for record keeping and files and other things were made to keep the records saved.

Uses Of Computer

What is a Computer?
A computer is an electronic device, which executes software programs. It consists of 2 parts-hardware and software . The computer processes input through input devices like mouse and keyboard. The computer displays output through output devices like color monitor and printer. The size of a computer varies considerably from very small to very big. The speed of computers also has a very large range. Computers have become indispensable in today’s world. Millions of people use computers all over the world.
