COMPUTER SCIENCE

The characteristics of computers that have made them so powerful and universally useful are speed, accuracy, diligence, versatility, and storage capacity. Let us discuss them briefly. Speed: -  As you know the computer can work very fast. It takes only a few seconds for calculations that we take hours to complete. You will be surprised to know that a computer can perform millions (1,000,000) of instructions and even more per second. Therefore, we determine the speed of the computer in terms of a microsecond (10-6 part of a second) or nanosecond (10 to the power -9 part of a second). From this, you can imagine how fast your computer performs work.  Diligence:   A computer is free from tiredness, lack of concentration, fatigue, etc. It can work for hours without creating any errors. If millions of calculations are to be performed, a computer will perform every calculation with the same accuracy. Due to this capability, it overpowers human beings in the

Meaning of the word computer Computer word derived from a Latin word "compute" which means "to calculate" "to count" "to sum up" or "think together". so, in short, the word computer means a device that performs computation". According to Wikipedia computer was first used in a book called "the young mans gleanings" in 1613. Definition - What does  Computer  mean? A computer is an electronic device or machine that can perform arithmetic operations (like addition, subtraction, multiplication, division, etc as well as logical operations (like comparisons). A computer is capable of receiving data or information in the form of input and perform a sequence of operations on it and give output to the user. In simpler words, computers accept data to store it manipulates it and gives a result. A computer is a programmed device with a set of instructions to perform specific tasks and generate results at a very high speed.
