Computer: The Definition

Computers! An amazing machine! We are living in the computer age today and most of our day to day activities cannot be accomplished without using computers. Sometimes knowingly and sometimes unknowingly we use computers.
For most of the people, computer is a machine used for calculations or computation, but actually, it is much more than that. Precisely, "Computer is an electronic device for performing arithmetic and logical operations", or " Computer is a device or flexible machine to process data and convert it into information".
We are breathing in the computer age and gradually computer has become such a dire necessity of life that it is difficult to imagine life without it. Computer is affecting every sphere of our life. Be it government, business, education, legal practice, entertainment, defense or home - computer has become an indispensable and multipurpose tool.
Whereas supercomputers can forecast weather, embedded computers make smart devices like washing machines that beep when washing is complete or the automobiles that give you warning before breaking down.
Computers are not only used for purpose of calculations. An accountant, a grocery shop owner, a bank or an ATM uses it like a computational device, where as an author uses it as writing tool, a musician as a device for controlling the music, kids as a machine for playing games and so on.
Now you must be thinking that what is so special about this machine that people from diversified fields can use it so flexibly for entirely different functions. The answer is that "computer is programmable" meaning that it all depends upon what program computer is using for performing a particular function.
Now, the next question that comes into one's mind is, what is a program? In a very simple language we can say that "A program is a set of instructions telling the computer what to do."
Broadly computer can be said to be made up of hardware and software. The computer hardware (actual machine ) is defined in such in a way that it does whatever the software ( computer programs ) tells it to do.
Computers have shaken up the world. They have made us dependent upon them. We expect them to be present at every place: be it the reservation counter, the microwave cooking or even driving a car. Now that computers have moved in our society so rapidly, one needs, at least the basic computer skills to pursue one's career goals and function effectively and efficiently. We can say that computer literacy is the need of today and voice of tomorrow to survive in the fast changing world of computers.
