Mainframe computing refers to the design, operation, and programming of large-scale mainframe systems that process massive volumes of transactions with high reliability and security. It typically involves technologies like IBM z/OS, COBOL, JCL, and CICS, and is maintained by systems programmers and operators in industries such as banking, insurance, and government. Despite predictions of decline, mainframe computing remains essential infrastructure for many large enterprises' core systems.
