IT Infrastructure and Networking
A mainframe is a large, highly reliable computer system designed for high-volume, mission-critical processing, such as banking transactions, airline reservations, and government records. Mainframes, most notably IBM's Z series, are prized for their processing power, uptime, and ability to handle massive transaction throughput securely. They remain in wide use in finance, insurance, and government sectors despite the growth of cloud computing.
