Digital computer: Learn what digital computers

Learn what digital computers are, how they work, and how they are structured. Explore the concepts of computer organization, design, and architecture, and the difference between von Neumann and Harvard architectures. 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. 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. 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 ...
