Mainframes is a legacy system....

Mainframes might fail in organizations because the organization has not planned for failure. By depending too much on a single mainframe computer, the organization and its systems can fail.
Typically mainframes run hundreds of terminals. PCs tend to be stand alone devices. In the old days mainframe computers were the size of refrigerators or larger. Today, however, you can achieve the equivalent in mainframe processing power by linking a series of PCs together with gigabit network interface cards, so the distinction gets a little blurry. In addition, mainframes do not have to act as big terminal servers to qualify as mainframes. Although mainframes are usually found in banks, large corporations, and universities, where they run hundreds of terminals, they are also used by scientists for massive modeling computations and in the scientific analysis of very large volumes of data.
