A Mainframe Computer (also known as "big iron") is a large, powerful, high-performance computer, often serving many connected terminals. It is used for large-scale computing purpose that require greater availability and security than a smaller-scale machine can offer.
Typically used in bulk data processing such as census, industry statistics, enterprise resource and financial transaction processing etc.
The original mainframes were housed in room-sized metal frames. In the past, a typical mainframe might have occupied 2,000-10,000 square feet. Newer mainframes are about the same size as a large refrigerator.
Mainframes are designed to handle very high volume input and output (I/O) and emphasize throughout computing.
IBM mainframes dominate the mainframe market at well over 90% market share.

This is very straight forward and clear way of explaining Mainframe ...
