Smaller and less expensive
PC-based servers are replacing mainframes in many business.
Mainframe computers
(colloquially referred to as "big iron") are computers used primarily
by large organizations for critical applications; bulk data processing, such as
census, industry and consumer statistics, enterprise resource planning; and
transaction processing.
Currently IBM system z is
the primary mainframe. Depending upon the definition, IBM isystem computers are
sometimes considered mainframes. Burroughs, Fujitsu, Hitachi, and Compaq (DEC)
make or made computers considered mainframes. The most prevalent current
example is the IBM Z mainframe.
z/OS, a widely used
mainframe operating system, is designed to offer a stable, secure, and
continuously available environment for applications running on the mainframe.
As a control program, z/Virtual Machine (z/VM) is a hypervisor because it runs
other operating systems in the virtual machines it creates.
