History of Unix before Linux

In the era of card readers only, MIT has developed its own set of time- sharing operating systems (computer time-sharing system CTSS) to improve efficiency, which enables multiple client connection hosts, Implement sharing of host resources. Due to its limited number of hosts, in order to enhance the host function by GE, MIT, Bell co-sponsored, build a powerful host- Multics. By 1969, the project lagged behind due to a shortage of funds, Bell quit.

　　Ken Thompson --a member of the Multics project. Because of their own needs, want to develop a small operating system, a DEC (Digital Equipment Corporation) launched by PDP-7 no one to use.
