FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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-i.e., using only the two digits 0 and 1.

Detailed explanation-2: -Binary describes a numbering scheme in which there are only two possible values for each digit–0 or 1–and is the basis for all binary code used in computing systems. These systems use this code to understand operational instructions and user input and to present a relevant output to the user.

Detailed explanation-3: -The operation of a digital computer is based on counting principle. It is based on digital signals i.e discrete signals. The basic principle of these computers is either present or absence of an electric pulse in the signals.

Detailed explanation-4: -All of the numbers we can possibly think of use some combination of these 10 digits. Computers, however, operate differently. Instead, they use a number system that has just two digits: one and zero. This system is called binary, and your computer uses it all the time.

Detailed explanation-5: -Examples of digital electronic computers include the IBM PC, the Apple Macintosh, and modern smartphones.
