As we interact with computers, we observe that computers
vary in sizes, logic and purposes and this has led to another classification of
computers. Based on size and capacity,
Supercomputers
are the largest and expensive computers in the world. They are housed in large
rooms as refrigerator-sized machines and require high skill personnel to operate
them. Many supercomputers have several processors that aid in the performing
complex tasks. The
mainframe computers are the second largest computers and cost lesser than the supercomputers. Mainframe computers can meet the needs of many users at the same time. Users are able to access its resources by means of a device called
terminal. Minicomputers have their size and capability between a mainframe and personal computer hence referred to as
mid-range computers. They can handle a sustainable amount of data and its performance is better compared to personal PCs.
