systems (super micro) are more powerful than some
midrange computer, while high-end models of mid range

systems (supermini) are more powerful than some smaller
models of mainframe computers.

It is also multi-user computer and supports more than dozen
of people at a time.

Use of minicomputers was over the year limits to dedicated
control system. Minicomputer
