Linux is an operating system for different types of computer and is free software. Linux was created by Linus Torvalds, at that time a young student, at Helsinki University in Finland. Linus needed functions other than the ones available in Unix, so he wrote his own operating system at machine level. As he added functions, eventually it all grew into a new operating system. Linux was called Freax initially, but he thought this was so ugly and so when he got his FTP directory on Funet, he quite simply renamed it Linux.

Unix is an operating system for different types of computer. Unix is derived from a system which was developed by Ken Thompson and Dennis Ritchie at AT&T Bell Labs in the USA in the 1960s and 1970s. The first Unix system was written in assembler by Ken Thompson on a Digital PDP-7 in 1969 after the development of [TEXT MISSING]. The name Unix was coined to go with Multics, which was designed for multiple users. This operating system had attracted a lot of attention by 1972. The program code for the original Unix remains in the Unix variant System V, which includes Solaris, Irix and AIX
