Minicomputers
Minicomputers are most powerful than microcomputers in terms of multiples user environments.In other words, a minicomputer can be used by many operators simultaneously. They have high processing speed and high storage capacity than the microcomputers.
A minicomputers can typically support 10 to 12 terminals, Minicomputer work well in what are known as distributed data processing i.e. a company’s processing power is decentralized, or distributed across different computers.
Many businesses and other organizations use minicomputers for their information processing requirements. They are very useful for scientists, engineers, smaller businesses, colleges and universities.
The most powerful minicomputers are called super minicomputers.
Mainframe Computers
Mainframe computers is a large computer system that has the capability to support more powerful peripheral devices and terminal.Mainframe computers are implemented using two or more central processing units CPU. The data storage capacity of these computers is very high.
It is multiuser, multiprogramming and high performance computers. They operate at a very high speed.
These types of computers are used for complex scientific calculations, large data processing application and for complex graphics applications.
Mainframe computers use a very sophisticated computer operating systems to manage and control the whole system. Most companies prefer to lease the computer rather than purchase it because of the high initial and maintenance cost.
Mainframes usually require a specialized environment including air conditioning and raised flooring at allows computer cables to be installed underneath.
The price ranges for mainframes from several hundred thousand to several million dollars. Government agencies, state and local agencies, banks, industries, manufacturers and hospitals are the major mainframe computer users.
