3 History of Unix AT&T, Bell Lab. - by Ken Thompson and Dennis Ritchie - Resource sharing, open system - Two versions of Unix : BSD (Berkeley), SVR4 (System V Release 4, AT&T) - TCP/IP protocol - Commercial Unix : IBM AIX, HP HP-UX, Silicon Graphics IRIX, Sun Microsystem Solaris, DEC Ultrix (acquired by Compaq acquired by HP) - Free Unix Linux (L. Torvalds, born December 28th 1969 in Helsinki, Finland), FreeBSD - Free Softwares (Richard Stallman), GNU= GNU s Not Unix,, GPL =General Public License Some peoples home pages Brian Kernighan, Dennis M. Ritchie, Ken Thompson developed Unix, C language Steve Jobs - CEO of Apple, reinvented the personal computer in the 1980s with the Macintosh OS Bill Joy - responsible for the authorship of Berkeley Unix (BSD), cofounder and Chief Scientist of Sun Microsystems Linus Torvalds Invent Linux Richard Stallman - founder of the free software movement, the GNU project, the Free Software Foundation The uniqueness of UNIX The features that made UNIX a hit from the start are: Multitasking capability time sharing operating system Multi-users capability

4 Portability UNIX programs Library of application software Multitasking capability Lets a computer do several things at once. Multi-users The same design that permits multitasking permits multiple users to use the computer. The computer can take the commands of a number of users. System portability UNIX tools - UNIX comes with hundreds of programs - UNIX - UNIX systems around the world were linked into a world wide web decades before the development of today's World Wide Web. Applications libraries Today there are hundreds of UNIX applications that can be purchased from third-party vendors, in addition to the applications that come with UNIX. How UNIX is organized The UNIX system is functionally organized at three levels: The kernel, which schedules tasks and manages storage; The shell, which connects and interprets users' commands, calls programs from memory, and executes them; and The tools and applications that offer additional functionality to the operating system References
