Large systems consist of mainframe computers, minicomputers and supercomputers.
They are typically multi-user computer system in which many users share the same computing resources at the same time (time sharing).
The computing power of minicomputers or mainframe is usually more than microcomputer, and so the cost is greater.
Mainframe computer and supercomputers can be very expensive to purchase and maintain, so only large corporations can afford them.
The computing power of mainframe computer is usually shared by many users.
That means that the operating system of a mainframe computer allows many computer users to participate simultaneously.
Mainframe computers are typically used for business applications where a large number of transactions are processed.
They are fast in processing speed and have large storage capacity.
Supercomputers have the most processing power of computers available.
They are primarily designed for high speed computation, especially for scientific research or the defense industry, but their use is growing rapidly in business as supercomputer prices decrease.
Supercomputers are also very valuable for large model simulation and complex mathematical calculations.
Weather forecasting agents use supercomputer to model the world’s weather system to improve prediction in a very short period of time.
The computer performance and speed required to achieve the above goal needs enormous speed and processing power.
To increase the speed of supercomputer, some companies are linking together individual or serial processors into multiple processors or parallel processing systems.
