Unix was one of the first operating systems written in C, a high-level programming language, and its natural portability and low price made it a popular choice among universities. Initially, two main dialects of Unix existed: one produced by AT&T known as System V, and one developed at UC...

UNIX can be seen in the architecture of operating systems such as BSD, Linux, and Mac OS, completely by design. One could say that without UNIX, there’d be no Mac OS, and quite possibly the same could be said about its competitors, Windows included. ...
Thompson earned abachelor’s degree(1965) and amaster’s degree(1966) inelectrical engineeringfrom theUniversity of California, Berkeley. After graduation, he went to work at Bell Labs, where he first worked on theMulticsoperating system (OS). Multics was atime-sharingsystem funded by theAdvanced...
UNIX served as the inspiration for many subsequent free open-source operating systems such as FreeBSD and Linux (which largely replaced UNIX), and it was the basis for Apple Inc.’s Mac OS X.The Editors of Encyclopaedia BritannicaThis article was most recently revised and updated by Erik ...
BeOS® - BeOS is an operating system for personal computers first developed by Be Inc. in 1991 built for digital media work with partial POSIX® compatibility. An open source replacement, Haiku, is under active development. NEWS-OS - NEWS-OS was an operating system from Sony based on BSD...
To load the OS a disk emulator was connected to the machine, and for possibly the first time in many decades a new UNIX version 0 device driver was written to enable it to be used. The first login was the user “dmr”, a homage to UNIX co-creator Dennis M. Ritchie. ...
