Digital computer: S are different from analog computers

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. 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. These values are processed internally by components that can maintain a limited number of discrete states. The decimal digits 0, 1, 2, ... , 9, for example, provide 10 discrete values. The first electronic digital computers, developed in the late 1940s, were used primarily ... 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. Computer, digital The digital computer [1] is a programmable electronic device that processes numbers and words accurately and at enormous speed. It comes in a variety of shapes and sizes, ranging from the familiar desktop microcomputer to the minicomputer, mainframe, and supercomputer.
