Application of PC's
Mainframe systems are computer system, Which are mainly used for handling the large data. These computers process large data so they are used in big organizations such as banks, insurance companies, hospitals, railways etc. They are also used in such enviorments in which a large number of users need to share a common computing facility, such as in research groups, educational institutions, etc. A typical configuaration of a mainframe system consists of a host computer a front-end computer a back-end computer. One or more server terminals, several magnetic disk drives, a few tape drives, a magnetic tape library, several user terminals, several printers and one or more plotters. A typical mainframe system looks like a row of large file cabinets. These computers need a room for installation.
Minicomputers were first developed by IBM Corporation and emerged in the mid-1960s. Mini Computer were primarily designed for business applications and services that require the performance and efficiency of mainframe computers. This computer are generally used as mid-range servers, where they can operate mid-sized software applications and support numerous users simultaneously. Minicomputers are inferior to mainframe computers both in speed and storage they can also support vaious terminals. In fact they can support up to 100 terminals Minicomputers have operating systems with multitasking and network capabilities enabling then to serve more then one user.
Super computer are most powerful and expansive computers. They are primarily used for processing complex scientific applications, which require enormous processing power. Some applications of super computers are as.
Super computers use multiprocessing and parallel processing technologies to solve complex problems faster, and hence they are known as parallel processing system.
