The document describes different types of computers: Mainframes are large, expensive systems that can be used by many people simultaneously and are used by governments, universities, and major industries. Minicomputers are smaller and less expensive than mainframes but can still be used by many users and are used by larger businesses. Microcomputers are smaller and cheaper than mainframes and minicomputers and are found in schools, homes, libraries, and small businesses.
