Classification of Computer Systems

Supercomputer
Supercomputers have the greatest computing power in terms of both their high processing speed and their large storage capacity. They are used primarily for complex calculations and programming tasks, and in advanced scientific or engineering laboratories such as weather observatories, space research, simulation experiments, natural landscape research, nuclear and military research, etc.

Mainframe Computer
Mainframe computers are large in volume and are more powerful than microcomputers in terms of computing power. They can handle an abundance of data quickly and can support thousands of users simultaneously. Mainframe computers are usually used as central appliances to provide computing power for an entire corporation or organization. As they are suitable for executing a lot of input and output application programs at once, they are – for example – highly useful for bank’s account management systems.

Minicomputer
The computing power of minicomputers lies between that of mainframe computers and microcomputers. As the storage capacity of minicomputers is smaller than that of mainframe computers, they are more suited to process more complex tasks that may require higher computing power, such as Computer Aided Design (CAD) and 3Danimated movie production. Minicomputers are suitable for general office tasks and can simultaneously support multiple users. They are popular in commercial enterprises, schools and government departments.

Microcomputer
Microcomputers are the smallest in volume and are equipped with general processing systems. Users can install the systems they need and use the microcomputers to complete tasks. Microcomputers are commonly found in schools, offices and homes. Most microcomputers are designed to be used by single user, as they are relatively small in volume and inexpensive.
