In today's fast growing business environment we still have the main frame computers with more power and very much user friendly as compared to the old main frame computers, the main frame computers are used by the large firms for the processing of there critical data which can't be processed by the normally used computers in offices and at homes, e.g. The financial data processing, ERP, industrial and consumer statistics etc. The other very common example of the main frame computers are the servers used by ISPs etc, the servers and the main frames are normally interchangeably used, there is another very important point i.e. Now a days the computers which are compatible with IBM System/360 lines are known as main frame computers.
