Digital Equipment Corporation (DEC) was an American company that was a major player in the computer industry from the 1960s to the 1990s. DEC was known for its minicomputers, which were highly successful and widely used in the scientific, educational, and business sectors. They also developed operating systems, programming languages, and other software tools. In 1998, DEC was acquired by Compaq Computer Corporation, which was later acquired by Hewlett-Packard (HP). Today, the heritage of DEC lives on within HP's technology solutions.
