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. Computers come in many different shapes and sizes, from smartphones to supercomputers weighing more than 300 tons.
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. Specific methods to make automated calculation more practical, such as ...
Computer - 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 ...
