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.周五, 27 3月 2026 21:09:00 GMThttps://www.britannica.com/technology/computer/History-of-computingComputer - History, Technology, Innovation: How did the abacus lead to modern computers? The earliest known calculating device is the abacus, dating back to at least 1100 BCE and still in use today, particularly in Asia. The abacus showed that calculations could be represented physically and manipulated systematically. Its use of discrete bead positions—on or off—anticipated the digital ...周日, 19 4月 2026 05:25:00 GMThttps://www.britannica.com/technology/computer/The-first-computerComputer - 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. Specific methods to make automated calculation more practical, such as ...周五, 10 4月 2026 06:12:00 GMThttps://www.britannica.com/science/computer-scienceComputer science is 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.周一, 20 4月 2026 10:25:00 GMThttps://www.britannica.com/summary/computercomputer, Programmable machine that can store, retrieve, and process data. A computer consists of the central processing unit (CPU), main memory (or random-access memory, RAM), and peripherals (e.g., a keyboard, a printer, disc drives). Traditional histories of computers assign generations on the basis of technology.周三, 08 4月 2026 07:55:00 GMThttps://www.britannica.com/technology/personal-computerPersonal 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.周日, 19 4月 2026 03:09:00 GMThttps://www.britannica.com/biography/Alan-TuringAlan Turing was a British mathematician and logician, a major contributor to mathematics, cryptanalysis, computer science, and artificial intelligence. He invented the universal Turing machine, an abstract computing machine that encapsulates the fundamental logical principles of the digital computer.周一, 20 4月 2026 07:33:00 GMThttps://www.britannica.com/question/What-is-a-computerA 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. Computers come in many different shapes and sizes, from smartphones to supercomputers weighing more than 300 tons.周五, 20 3月 2026 08:46:00 GMThttps://www.britannica.com/technology/computer/SupercomputerComputer - Supercomputing, Processing, Speed: The most powerful computers of the day have typically been called supercomputers.
