Mainframe Computer:-

• A very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously.

• In the hierarchy that starts with a simple microprocessor (in watches, for example) at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers.

• In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But supercomputers can execute a single program faster than a mainframe.
