Digital computers are different from analog computers in the sense that analog computer process the analog data. Here the term analog represents continuous data . The digital computer takes the binary data at input, processes according to the set of instructions called program and produces the digital output. A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs, which enable computers to perform a wide range of tasks. What are Digital Computers? The digital computer is a digital system that performs various computational tasks. The word digital implies that the information in the computer is represented by variables that take a limited number of discrete values. Digital computer, any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary code—that is, using only the two digits 0 and 1.
