Evolution & Development History
In the late 1960s a feature project between researchers at MIT, Bell Labs and General electric car led to the design of a third generation of computing device operating system cognize as MULTICS (MULTiplexed Information and reckoning Service). It was envisaged as a computer utility, a machine that would take over hundreds of simultaneous timesharing users. They envisaged one huge machine providing computing military unit for everyone in Boston. The idea that machines as powerful as their GE-645 would be sold as personal computers costing only a few thousand dollars only 20 years posterior would have seemed like science fiction to them. However MULTICS turn out more difficult than imagined to implement and Bell Labs withdrew from the project in 1969 as did General Electric, dropping out of the computer production line altogether.
One of the Bell Labs researchers (Ken Thompson) then decided to rewrite a barren down var. of MULTICS, initially as a hobby. He used a PDP-7 minicomputer that no was using and wrote the code in assembly. It was initially a stripped down, single user version of MULTICS but Thompson actually got the system to work and one of his colleagues banteringly called it UNICS (UNiplexed Information and Computing Service). The name stuck but the spelling was ulterior changed to UNIX. Soon Thompson was joined on the project by Dennis Richie and later(prenominal) by his entire department.
UNIX was moved from the now obsolete PDP-7 to the more more modern PDP-11/20 and then later to the PDP-11/45 and PDP-11/70. These two latter computers had large memories as well as memory protection hardware, making it possible to support three-fold users at the same time. Thompson then decided to rewrite UNIX in a high-level language called B. Unfortunately this attempt was non successful and Richie designed a successor to B called...

-->I thought that this essay as presented excellently. It was correctly structured, clear, concise and was a diversion to read.
I read through most of it (it is quite long). The essay is extremely informative and the writing is excellent. It thoroughly describes the UNIX and Windows operating systems and effectively compares them.
