What is a Mainframe?

A Mainframe is a high power, high performance computer used for large scale information processing. It can run multiple operating systems and handle high volumes of data input and output making it ideal for computing large amounts of information such as statistics or financial transactions. As such is most often used by large corporations that require a greater level of processing power, security and storage, replacing the need for several smaller servers.

Although Mainframes are now around the size of a refrigerator, the name refers back to when these machines were stored in large metal frames the size of rooms.
