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.Tue, 24 Mar 2026 15:50:00 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.Fri, 20 Mar 2026 08:46:00 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 ...Mon, 30 Mar 2026 07:15:00 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 ...Sun, 05 Apr 2026 04:52:00 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.Tue, 24 Mar 2026 10:07:00 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.Thu, 02 Apr 2026 05:10:00 GMThttps://www.britannica.com/technology/computer/The-personal-computer-revolutionComputer - 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. The machines were expensive and difficult to use. Few people came in direct contact with them, not even their programmers ...Fri, 03 Apr 2026 05:23:00 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.Mon, 06 Apr 2026 08:47:00 GMThttps://www.britannica.com/technology/computer/Transistor-sizeComputer - Miniaturization, Transistors, Chips: The size of transistor elements continually decreases in order to pack more on a chip. In 2001 a transistor commonly had dimensions of 0.25 μm (or micrometer; 1 μm = 10−6 meter), and 0.1 μm was common in 2006. This latter size allowed 200 million transistors to be placed on a chip (rather than about 40 million in 2001). Because the ...Fri, 03 Apr 2026 06:13:00 GMThttps://www.britannica.com/technology/computer/Main-memoryComputer - Memory, Storage, Processing: The earliest forms of computer main memory were mercury delay lines, which were tubes of mercury that stored data as ultrasonic waves, and cathode-ray tubes, which stored data as charges on the tubes’ screens. The magnetic drum, invented about 1948, used an iron oxide coating on a rotating drum to store data and programs as magnetic patterns. In a ...Fri, 27 Mar 2026 20:26:00 GMT
