What Is a Computer? We are all familiar with what a compute is in a specific, contemporary sense. Personal computers are found in most aspects of daily life, and for some it is hard to even imagine a world without them .But the term computer means more than simply the Macs and PCs we are familiar with. A computer is, at its most basic, a machine which can take instructions, and perform computations based on those instructions. It is the ability to take instructions-often known as programs in the parlance of computer-and execute them that distinguishes a computer from a mechanical calculator. While both are able to make computations, a calculator responds simply to immediate input. I in fact , most modern calculator are actually computers with a n umber of pre-installed programs to help a aid in complex task . Computers range from the very small to very large. Some are capable of doing millions of calculations in a single second, while others may take long periods of time to do even the most simple calculations. But theoretically, anything the right instructions, and sufficient memory, a computer found in a wristwatch should be able to accomplish anything a supercomputer can –although it might take thousands of years for the wristwatch to complete the operation.
