What is mainframe ?
A data processing system employed mainly in large
organizations for various applications, including bulk data processing, process
control, industry and consumer statistics, enterprise resource planning, and
financial transaction processing.
Mainframes use proprietary operating systems, most
of which are based on Unix, and a growing number on Linux. Over the years they
have evolved from being room-sized to networked configurations of workstations
and servers that are an extremely competitive and cost effective platforms for
e-commerce development and hosting. Mainframes are so called because the
earliest ones were housed in large metal frames.
