Operatsiooni süsteemid

Operatsiooni süsteem (OS) on TARKVARA, mis haldab arvuti riistvara ja tarkvara resursse ja pakub arvuti progammidele ja kasutajale teenuseid.

Moodsad operatsiooni süsteemid- Android, BSD, iOS, Linux, OS X, QNX, Microsoft Windows,^[3] Windows Phone, and IBM z/OS.

1. Android- telefonide operatsiooni süsteem, põhineb Linuxi tuumal, preagu arendavad seda Google. Tavaliselt puutetundlik telefon
2. BDS- Berkeley Software Distribution (BSD) was a Unix operating system derivative developed and distributed by the Computer Systems Research Group (CSRG) of the University of California, Berkeley, from 1977 to 1995. Today the term "BSD" is often used non-specifically to refer to any of the BSD descendants which together form a branch of the family of Unix-like operating systems. Operating systems derived from the original BSD code remain actively developed and widely used.
3. iOS- (previously iPhone OS) is a mobile operating system developed by Apple Inc. and distributed exclusively for Apple hardware. It is the operating system that powers many of the company's iDevices.
4. Linux- is a Unix-like and mostly POSIX-compliant^[8] computer operating system assembled under the model of free and open-source software development and distribution
5. OS X- /ˌoʊ ɛs ˈtɛn/,^[10] formerly known as Mac OS X,^[11] is a series of Unix-based graphical interface operating systems developed and marketed by Apple Inc.
6. QNX- is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market.
7. Microsoft Windows- is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft.
8. Windows Phone-  is a smartphone operating system developed by Microsoft
9. IMB z/OS- is a 64-bit operating system for mainframe computers, produced by IBM.

System Call IT = AP
Kaks alamsüsteemi on AP'il- Process Control alasüsteem

5) Kõige uuem versioon on Yosemite. Versioon 10.10- 11th release \o/
7)Kõige uuem versioon on Windows 8. Praegu proovitakse windows 8.1, mis kui välja tuleb on Windows 10. 5th release :3 ( http://en.wikipedia.org/wiki/List_of_Microsoft_Windows_versions )
Telefonidel on manus operatsioonide süsteemid.

Millised operatsiooni süsteeme kasutakse?

-Statistic II
Windows Juhib! 

PS- read the wikipedia!
Mida arvuti teeb katlamajas vms!

Kõige tähtsam selles

• Protsessi juhtimine
• Katkestused
• Memory management
• Faili süsteemid
• Seadme ajur
• Networking
• Security
• I / O  

 Katkestused- Kell ehk Taktigenenaator
   Tööd tehakse jupi kaupa.

Memory management- koguaeg oleks mälu (YKWIM)
File System- NTFS (New Technology file System)
Seadme Ajur(Device Driver)- kuidas riistvara ära tunda ja tööle saada
Networking- Võimaldab võrgus töötamist
Security- pidevalt tegeleme sellega
I/O- intput/output. Suhtlust seadmete vahele.
