Computer Network | PDF A computer is a programmable device for processing, storing, and displaying information. learn more in this article about modern digital electronic computers and their design, constituent parts, and applications as well as about the history of computing. A computer is a machine that can store and process information. most computers rely on a binary system, which uses two variables, 0 and 1, to complete tasks such as storing data, calculating algorithms, and displaying information.

Computer Network | PDF By the second decade of the 19th century, a number of ideas necessary for the invention of the computer were in the air. first, the potential benefits to science and industry of being able to automate routine calculations were appreciated, as they had not been a century earlier. Computer science is the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information. The history of the solving of these problems is the history of the computer. that history is covered in this section, and links are provided to entries on many of the individuals and companies mentioned. Personal computer (pc), a digital computer designed for use by only one person at a time.

Personal computer (pc), a digital computer designed for use by only one person at a time. Computer software is divided into two basic types—the operating system and application software. the operating system controls how the different parts of hardware work together. application software gives the computer instructions for doing specific tasks, such as word processing or playing games. Computer home use, microprocessors, software: before 1970, computers were big machines requiring thousands of separate transistors. they were operated by specialized technicians, who often dressed in white lab coats and were commonly referred to as a computer priesthood. John mauchly (born august 30, 1907, cincinnati, ohio, u.s.—died january 8, 1980, ambler, pennsylvania) was an american physicist and engineer, co inventor in 1946, with john p. eckert, of the electronic numerical integrator and computer (eniac), the first general purpose electronic computer. The first digital computer designed with internal programming capacity was the “baby,” constructed at manchester in 1948. a program is prepared by first formulating a task and then expressing it in an appropriate computer language, presumably one suited to the application.
