A mainframe is a large powerful computer that serves many users (hundreds) simultaneously and is sued by large companies for bulk data processing, running several programs simultaneously and sharing of resources amongst the organisations various computer users.
The term ‘mainframe’ was coined in the 1970s when the smaller minicomputers began available. In those days mainframes were huge and could occupy a whole room or take out an entire floor. Today mainframes have decreased in size nut with in an increase in computing power and are sometimes referred to as large servers.
In the 1960s and the 1970s, mainframes were popular, with quite a number of manufacturers, but the arrival of the cheaper microcomputers and the concept of distributed computing reduced the demand for mainframes and a lot of the companies went under.
