Mainframe computer
A mainframe computer is a powerful, large-scale machine designed to handle extensive processing tasks and manage vast amounts of data simultaneously. Used primarily by large organizations like banks, government agencies, and corporations, mainframes ensure high reliability, security, and uptime for critical operations. They can support thousands of users and run multiple applications at once, making them essential for tasks such as transaction processing, data storage, and complex computations. Despite the rise of smaller servers and cloud computing, mainframes remain vital where processing power, data integrity, and operational continuity are paramount.
