UNIX was developed in 1970 by Kenneth Thompson and Dennis Ritchie at AT&T Bell Labs on the PDP-7
system. And three years later he was rewritten in the C programming language and UNIX became a widely used
freeware product. This is a versatile, multi-user, interactive operating system.
Major changes:
=> File system hierarchy including mountable volumes, compatible files, and interprocess I/O. In contrast to UNIX, the MULTICS (predecessor to UNIX) file system hierarchy was complex and resource-expensive.
LINUX DEVELOPMENT:
=> Linux is a freely available open-source operating system developed by Linus Torvalds in 1991 as a school project
. Initially, it only supported Intel 80x86 processors, but now it can run a wide range of processors including Intel
IA-32, Intel IA-64, AMD, DEC, PowerPC, Motorola, SPARC and IBM S/390.
