2024年12月20日 · 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.

2024年12月20日 · Computer - History, Technology, Innovation: A computer might be described with deceptive simplicity as “an apparatus that performs routine calculations automatically.” Such a definition would owe its deceptiveness to a naive and narrow view of calculation as a strictly mathematical process.

2025年1月29日 · Computer science, the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information. The discipline of computer science includes the study of algorithms and data structures and artificial intelligence.

2024年12月20日 · Computer - Technology, Invention, History: 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.

6 天之前 · Personal computer, a digital computer designed for use by only one person at a time. A typical personal computer assemblage consists of a central processing unit, which contains the computer’s arithmetic, logic, and control circuitry on an integrated circuit; computer memory; and various peripheral devices.

A computer is a device for working with information. The information can be numbers, words, pictures, movies, or sounds. Computer information is also called data.

2025年1月13日 · Ada Lovelace, English mathematician, an associate of Charles Babbage, for whose digital computer prototype, the Analytical Engine, she created a program in 1843. She has been called the first computer programmer.

2025年1月25日 · ENIAC, the first programmable general-purpose electronic digital computer, built during World War II by the United States and completed in 1946. The project was led by John Mauchly, J. Presper Eckert, Jr., and their colleagues. ENIAC was the most powerful calculating device built to that time.

Computer simulation, the use of a computer to represent the dynamic responses of one system by the behavior of another system modeled after it. A simulation uses a mathematical description, or model, of a real system in the form of a computer program.
