What do you understand by mainframe computer? Distinguish between mainframe computer and super computer.

Mainframe computers are large-sized, powerful multi-user computers that can execute multiple programs concurrently. That means, they can perform different actions or 'processes' at the same time. Mainframe computers can be used by as many as hundreds or thousands of users at the same time. Large organizations may use a mainframe computer to execute large-scale processes such as processing the organization's payroll, critical backend data processing, data warehousing etc. Main difference between a super computer and a mainframe is that a super computer channels all its power into executing a few programs as fast as possible, whereas a mainframe uses its power to execute many programs concurrently. In some ways, mainframes are more powerful than super computers because they support more simultaneous programs. But super computers can execute a single program faster than a mainframe.
