MAINFRAME is a some what antiquated term for a main server or a large machine capable of a workload much beyond the capability of a standard desktop unit. Also called "servers" or "Big iron" or even "gibsons" after the author of sci-fi novels the term has fallen into disuse these days.
Rare is it to see people putting all their money into a mainframe any longer. Parallel computing and cluster computing has enabled server farms to do the work of a mainframe for less money and less power! If you wish to see an example of what might be called a "Mainframe" check out the manufacturer "Cray" for some of their super computers.

The term 'mainframe' was coined in reference to the large cabinets used to house high-end server systems. Mainframes are highly-reliable, high-throughput servers; they focus on the reliable handling of vast amounts of data in/out (throughput) as opposed to pure processing speed, whereas supercomputers process specific sets of tasks/calculations rapidly. Mainframes and server farms perform similar functions with differing outlay, cost, reliability, power consumption and performance profiles.
Mainframes typically employ multiple redundant systems, multiple central processors, peripheral processors (to which hardware I/O operations are off-loaded), can operate multiple virtual machines concurrently, and access vast storage volumes at great speed. They operate for substantial periods of time without interruption for purposes where down time would be unacceptable, and they typically process databases of gigabytes (or even terabytes) in size extremely rapidly.
Financial institutions, corporations, government departments, and anyone needing to ensure the uninterrupted processing and reliability of large volumes of data typically make use of mainframes.
Commercial and personal computer use is increasingly offloading data storage and processing to 'the cloud'; cloud computing, email servers, web hosts and social networking sites, and many other online systems are facilitated by server farms or mainframes. Even gaming servers can exist as one among many virtual machines running in a single mainframe or somewhere in a server farm.
Mainframe Systems are real time transactions processing systems generally used by Organisations those have business operations generating huge volume of transactions such as Banking, Railways, Telecoms etc.
almost no one still uses a mainframe setup in a network anymore. the server-client system replaced it in the mid eighties.
