Mainframe

A mainframe is a powerful, large-scale computer designed to handle vast amounts of data and numerous simultaneous tasks reliably and securely. Think of it as the central nervous system of large organizations like banks, insurance companies, or government agencies, managing critical operations such as transaction processing, data storage, and complex business applications. Mainframes are known for their high performance, fault tolerance, and ability to operate continuously without interruption, making them essential for environments where stability, security, and massive throughput are paramount.
