# Mainframe computers
|
||
|
|
|
||
|
|
A mainframe computer, also known as a "big iron" is a high performance computer
|
||
|
|
used for resource-intensive tasks that require greater security and availability
|
||
|
|
than smaller scale machines. They are typically used for centralised rather than
|
||
|
|
distributed computing.
|
||
|
|
|
||
|
|
The heyday of mainframes was before the mini- and micro-computer revolution but
|
||
|
|
they are still used.
|
||
|
|
|
||
|
|
IBM remains the main manufacturer and service provider for mainframes. Example
|
||
|
|
use cases include banks who need to process large volumes of transatction and
|
||
|
|
high frequency tranding; government departments, the military and internal
|
||
|
|
revenue who require huge databases.
