Multics
Multics ("Multiplexed Information and Computing Service") eskiden kullanılmış aynı anda birkaç işlem yapabilen (time-sharing) işletim sistemi idi. Proje 1964 yılında Cambridge, Massachusetts'de başlamıştır. Son çalışan işletim sistemi ise 30 Ekim 2000'de Kanada Ulusal Savunma Departmanı'nda kullanılmış ve daha sonra kapatılmıştır.[1]
Ek okumalar
The literature contains a large number of papers about Multics, and various components of it; a fairly complete list is available here.[2] The most important and/or informative ones are listed below.

Teknik detaylar
- Jerome H. Saltzer, Introduction to Multics (MIT Project MAC, 1974) is a considerably longer introduction to the system, geared towards actual users.
- Elliott I. Organick, The Multics System: An Examination of Its Structure (MIT Press, 1972) is the standard work on the system, although it documents an early version, and some features described therein never appeared in the actual system.
- V. A. Vyssotsky, F. J. Corbató, R. M. Graham, Structure of the Multics Supervisor16 Ocak 2014 tarihinde Wayback Machine sitesinde arşivlendi. (AFIPS 1965) describes the basic internal structure of the Multics kernel.
- Jerome H. Saltzer, Traffic Control in a Multiplexed Computer System (MIT Project MAC, June 1966) is the original description of the idea of switching kernel stacks; one of the classic papers of computer science.

- R. J. Feiertag, E. I. Organick, The Multics Input/Output System4 Haziran 2013 tarihinde Wayback Machine sitesinde arşivlendi.. Describes the lower levels of the I/O implementation.
- A. Bensoussan, C. T. Clingen, R. C. Daley, The Multics Virtual Memory: Concepts and Design18 Ocak 2010 tarihinde Wayback Machine sitesinde arşivlendi. {{|url=https://web.archive.org/web/20100118014733/http://www.multicians.org/multics-vm.html |tarih=18 Ocak 2010 }}, (ACM SOSP, 1969) describes the Multics memory system in some detail.
- Paul Green, Multics Virtual Memory - Tutorial and Reflections5 Mart 2001 tarihinde Wayback Machine sitesinde arşivlendi. {{|url=https://web.archive.org/web/20010305133541/http://ftp.stratus.com/pub/vos/multics/pg/mvm.html |tarih=5 Mart 2001 }} is a good in-depth look at the Multics storage system.

Güvenlik
- Paul A. Karger, Roger R. Schell, Multics Security Evaluation: Vulnerability Analysis9 Temmuz 2011 tarihinde Wayback Machine sitesinde arşivlendi. {{|url=https://web.archive.org/web/20110709024412/http://csrc.nist.gov/publications/history/karg74.pdf |tarih=9 Temmuz 2011 }} (Air Force Electronic Systems Division, 1974) describes the classic attacks on Multics security by a "tiger team".

Schroeder, The Protection of Information in Computer Systems9 Temmuz 2011 tarihinde Wayback Machine sitesinde arşivlendi. {{|url=https://web.archive.org/web/20110709033025/http://cap-lore.com/CapTheory/ProtInf/ |tarih=9 Temmuz 2011 }} (Proceedings of the IEEE, September 1975) describes the fundamentals behind the first round of security upgrades; another classic paper.
- M. D. Schroeder, D. D. Clark, J. H. Saltzer, D. H. Wells. Final Report of the Multics Kernel Design Project (MIT LCS, 1978) describes the security upgrades added to produce an even more improved version.
- Paul A. Karger, Roger R. Schell, Thirty Years Later: Lessons from the Multics Security Evaluation24 Temmuz 2014 tarihinde Wayback Machine sitesinde arşivlendi. (IBM, 2002) is an interesting retrospective which compares actual deployed security in today's hostile environment with what was demonstrated to be possible decades ago. It concludes that Multics offered considerably stronger security than most systems commercially available in 2002.
