What is Unix?
Unix was developed by AT&T
Bell Laboratories by Ken Thompson in the late 1960's for use by engineers
and scientists. Its use has grown, and there are now several modifications
to the AT&T standard. It is also the operating system upon which nearly
all of the standard networking protocols, such as TELNET and FTP, are
based. There are several shell command interpreters available, the most
common being Berkeley, Bourne, Korn and C shells. Unix is a generic operating
system that takes advantage of available hardware power, written almost
entirely in a machine-independent language. It is easily adapted to run
on different hardware platforms. Because Unix was designed initially to
run on minicomputers, the file structure takes full advantage of large,
fast disks. Unix is a multi-user operating system; the ability to share
data and programs among many users is a central feature.
