Kenneth Thompson and Dennis Ritchie, programmers at AT&T labs develop the UNIX operating system on a spare DEC computer. UNIX was based on the same features of Multics, namely file sharing capabilities and file management features. Multics was a project established in the early 1960’s in an effort to create a multi-user, multi-tasking operating system. UNIX gathered a large amount of attention, mainly from engineers and scientists. UNIX is the basis of our worlds computing infrastructure.
