Information System Hardware-revolution from mainframe computer systems to microcomputer systems

Today, we would like to explain about the revolution of computer systems from mainframe computer systems  to microcomputer systems.


Mainframe Computer Systems

A mainframe is large in size. It is also fast and powerful computer systems. Mainframe computer systems have large primary storage capacity and high transaction processing. It can carry out millions of instructions per second.


Mainframe computer systems is widely used as superservers for large client, server networks, high-volume internet websites.
Mainframe computer systems is becoming a popular computing platform for data mining, warehousing and electronic commerce applications.
You can refer to this website (http://www.vikingwaters.com/htmlpages/MFHistory.htm) to know about the history for mainframe computer systems.




Midrange Computer Systems

Midrange computer systems is high-end network servers that handle large-scale processing of business applications. However, midrange computer systems are not as powerful as mainframe. Besides that, midrange computer systems are less expensive to buy, operate and maintain.

Mainframe computer systems are often used to manage large internet websites, corporate intranets and extranets, integrated, enterprise-wide applications. In addition, it is also used as front-end servers to assist mainframes with telecommunications and networks.


Microcomputer Systems

Microcomputer systems are usually called as personal computer or PC. The computing power now exceeds that of the mainframes of previous generations. PC is also relatively inexpensive. Microcomputer systems are the networked professional workstations used by business processions. Usually there is only 1 user for microcomputer systems.
