Where does Mainframes are used
Today, mainframe computers play a central role in the daily operations of most of the world’s largest corporations.

Many schools and other educational institutions use centralized mainframe computers to store information pertaining to students, school courses and teachers. Localized terminals linked with a centralized mainframe “repository” allow authorized users to access the stored information. Students access software programs and files stored on the mainframe computer simultaneously using individual terminals.
