What Is Computer?
A computer is an electronic device or machine this is used to solve different problems, according to a set of instructions given to it. A computer can accept data, process data into useful information and also stores it for future use.
The word “computer” is derived from the word “compute” which means to calculate. The computer can also be used as a calculating machine to produce results at a very high speed. However, the calculation is not the only use of the computer. It can be used for different purposes. People use computers to solve different problems quickly and easily.

Computer Literacy: The term computer literacy refers to the knowledge and understanding of computer and its uses. A person is computer literate if he understands computer and its applications.
Characteristics Of Computer
The important characteristics of computer are as follows:
Computer processes data at a very high speed. It is much faster than human beings. A computer can perform billions of calculations in a second. Computer speed is measured in MegaHertz (MHz) or GigaHertz (GHz). For example, the process of multiplying 720 and 987 can take one or two minutes if it is performed by human beings. However, A computer can perform millions of calculations within few seconds.
The computer is very reliable. The electronic components in modern computers rarely break or fail.
Accuracy means that the computer provides results without any error. The computer can process a large amount of data and produce result accuracy. The result can be wrong only if the data given to the computer is not correct. Suppose the average marks of a class are required. There can be a chance of mistake in the result if it is performed by human beings. However, a computer can produce this result very accurately and quickly.
A computer can store a large amount of data permanently. People can use this data at any time. The user can store any type of data on the computer. The storage capacity of the computer is increasing rapidly. A computer can store thousands of images, videos, documents and other important data easily.
Most computers today have the capability of communicating with other computers. We can connect two or more computers by a communicating device such as a modem.

8- Control Sequence:
A computer works strictly according to the given instructions. It follows the same sequence of execution that is given in a program.
A computer can recall the stored data and information as and when required. The data stored in the computer can be used at a later time. The computer can recall the required data in a few seconds.
10- Cost Reduction:
We can perform a difficult task in less time and less cost. For example, we may have to hire many people to handle an office. The same work can be performed by a single person with the help of a computer. It reduces the cost.
