👉 Cobol, also known as Computer-Based Operating System (CBOSS), is a programming language developed by IBM and later by other companies. It was designed to be used for development of computer languages and was intended primarily for use in the IBM mainframe system. Cobol is distinguished from other programming languages because it has been specifically designed for use on the IBM mainframes, which were large-scale machines with limited memory and were unable to run traditional languages such as C or FORTRAN.
