What is Mainframe?

Mainframe is a High performance Multi User computer system which is the most scalable, available, reliable and secured machine in the world capable of performing some Million Instructions per second (upto 569,632 MIPS).Historically, mainfra mes have been associated with centralized rather than distributed computing, although that distinction is blurring as smaller computers become more powerful and mainframes become more multi-purpose. Mainframes are very large computers that are built to be able to perform complex and critical applications. Mainframes are usually very large in both physical size and computational ability. They can be some of the largest machines on the planet. However, given the continued drive towards greater computational muscle in a smaller physical package, many mainframes are not too much larger than desktop computers these days.
