UNIVAC is the Universal Automatic Computer. The basic operations performed by computers are arithmetic, logical, and storage operations. The two major types of computer chips are primary memory chips and microprocessor chips. Supercomputers are focused on executing few programs as fast as possible, while mainframes can execute many programs concurrently. A compiler translates instructions of a high-level language into machine language.
