Mainframe- are computers used mainly by large organizations for critical applications, typically bulk data processing such as census, industry and consumer statistics, ERP and financial transaction processing. The term probably originated from the early mainframes, as they were housed in enormous, room-sized metal boxes or frames. Later the term was used to distinguish high-end commercial machines from less powerful units. Some non-System/360 comptible systems derived from or compatible with older (pre-web) server techonlogy may also be considered mainframes. These include the Burroughs large systems, the UNIVAC 1100/2200 series systems, and the pre-system 360 IBM 700/700 series. Most large- scale computer system architectures were firmly established in the 1960s and most large computers were based on architecture established during that era up until the advent of Web servers in the 1990.
PC(Personal Computer)-is any computer whose original sales price, size, and capabilities make it useful for individuals, and which is intended to be operated directly by an end user with no intervening computer operator. Today a PC may be a desktop computer, a laptop computer or a tablet computer. The most common operating system are Microsoft Windows, Mac OS and Linux, while the most common microprocessors are x86-compatible CPUs. Software applications for personal computers include word processing, spreadsheets, database, games, and myraid of personal productivity and special-purpose software. Modern personal computers often have high-speed or dial-up connections to the internet, allowing access to the World Wide Web and a wide range of other resources. A PC may be a home computer or may be found in an office often connected to a local area network.
