COMPUTERS - Mainframe Systems

What are Mainframe Systems?

They are the really big computer systems used in the corporate world; banks, big and medium businesses, NASDAQ, Governments, etc.

They also tend to be physically big. Components mounted in a 6ft high rack for example, not a desktop.

They also may have components combined in separate Functional Blocks (Generic Computer). Example, one system at Unisys has a "Cell" = MPUs (4 to 16) + Memory (2 to 32gb) + Bus Extender Cards. These Bus Extender Cards essentially make all PCI bus systems look/act as if they were just one bus. Therefore the system could interface with the MPUs and Memory.
