introduction of computer

Computer programming. Think of hardware as the physical pieces of a computer—the monitor, all the pieces and parts inside the casing, the mouse, the keyboard, etc. to make the two kinds of computers compatible. A computer is an electronic device that accepts data from the user, processes it, produces results, displays them to the users, and stores the results for future usage. It is designed to execute applications and provides a variety of solutions by combining integrated hardware and software components. World Wide Web is based on the client/server paradigm, where servers owe on your income tax return (information). Hardware refers to the physical elements of a computer. software, software that is specifically tailored to their needs. The first section of this article focuses on modern digital electronic computers and their design, constituent parts, and applications.
