A main frame is basically a Huge computer that can be used as a server as well. They are not like most computers Mainframes need to be kept cool due to the heat they produce and a main frame is a very expensive super computer that only internet service providers and computing experts can use and control
distributed
IBM system 3 and AS-400 are some examples of minicomputers.
Computer terminals that have no computing power contend for access to the mainframe computer for computing that is then sent back to the respective computer terminal.
There are many places where one can find out more about how a mainframe works. This includes reading computing infrastructure books from your local library and blogs dedicated to the subject.
Terminal Services
Information systems using a mainframe are referred to as distributed because computing results must be distributed to users at various locations.
The mainframe computers used to guide the astronauts to the moon had less computing power than a computer watch.
Information systems using a mainframe are referred to as distributed because computing results must be distributed to users at various locations.
The five eras of Data processing starts with Mainframe computers, personal computers, client server, enterprise and cloud computing. Now the era goes in cloud computing.
Mainframe systems use dumb terminals, a client/server environment uses intelligent terminals. Cross-platform computing and distributed processing is supported in client/server architecture, but not possible in a mainframe. There can be any numbers of servers and clients in a CSA, while mainframes work on the principle of the central server.
The advantages of a mainframe computer include more computing power and a maximum amount of storage space. The disadvantages include the large amount of space that a mainframe takes to store and the amount of energy required to power and cool this type of computer.
a mainframe is a high performance computer used for large-scale computing purposes that require greater availability and security than a smaller-scale machine can offer.
