Solution :
[a] Unix (trademarked as UNIX) is a family of multitasking multiuser computer operating systems that derive from the original AT&T Unix, developed in the 1970s at the Bell Labs research centre by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties from the late 1970s, leading to a variety of both academic and commercial variants of Unix from vendors such as the University of California, Berkeley (BSD), Microsoft (Xenix), IBM (AIX) and Sun Microsystems (Solaris).You need to login to perform this action.
