mainframe computer

Also known as mainframe, big iron, mainframes

computers used primarily by large organizations for critical applications

AI overview

A mainframe computer is a large, powerful computer used primarily by big organizations like banks, governments, and insurance companies to run their most critical operations. These machines matter because they're built to handle enormous amounts of data and transactions reliably, keeping essential services running smoothly around the clock.

A mainframe computer, informally called a mainframe, maxicomputer, or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers.
