Sistem operasi adalah perangkat lunak yang mengontrol dan mengelola perangkat keras komputer serta menjalankan aplikasi. Sistem operasi memiliki fungsi utama seperti menjalankan komputer, menyediakan antarmuka pengguna, mengelola program, mengelola memori, dan mengontrol jaringan. Ada berbagai jenis sistem operasi seperti mainframe, embedded, Unix-like, Mac OS, Windows, jaringan, dan webOS. Program utilitas seperti antivirus dan firewall juga membantu sistem

6. Booting
 Cold booting, menghidupkan
komputer dalam keadaan mati (off)
 Warm booting, restart.

7. Klasifikasi Sistem Operasi

8. Pembagian Sistem Operasi
 Mainframes
 Embedded System
 Unix-like Operating System
 Mac OS
 Microsoft Windows
 Network OS
 WebOS

9. Mainframes
 Mainframes run multiple operating
systems and operate not as a single
computer but as a number of virtual
machines.
 They are typically manufactured by
large companies for large-scale
computing purposes

10. Mainframes
 z/OS from IBM
While IBM System z™ servers are
supported by a number of different
operating systems, their most
advanced features are powered by
z/OS

11. Embedded Systems
 Embedded systems are special-purpose
systems in which the computer is
completely encapsulated by the device it
controls.
 Embedded systems perform pre-defined
tasks that have very specific requirements.
 Real-time operating systems are embedded
systems with certain time requirements

12. Embedded Systems
 Symbian OS for smartphone
 Cisco IOS for router and switch
 iPodLinux for ipods
 Windows CE.Net
 Windows Mobile 2003

13. Unix-like OS
 The operating system Unix was
developed in 1960 by a group of AT&T
employees.
 Free Unix-like operating systems can be
used, studied, modified and
redistributed by anyone with no
restrictions.

14. Unix-like OS
 It's a diverse group of operating systems
with several major sub-categories
including BSD, and Linux.
 Unix like operating systems run on a
variety of computers but more
frequently on server systems and in
academic and engineering environments
due to high stability for any kind of
processing

15. Unix-like OS
 Ubuntu
 FreeBSD
 openSUSE
 Debian
 Fedora

16. Mac OS
 Apple's Macintosh OS is an operating
system with a very innovative and unique
design.
 The history of the company behind it,
Apple, that's been around since 1976 is
fascinating and so is its cool operating
system Mac OS.
 Leopard merupakan versi Mac OS terbaru
(http://www.apple.com/macosx/)

17. Microsoft OS

18. Network OS
 Sistem Operasi yang berbasis
jaringan
 Contoh:
 Novell Netware
 Windows Server 2003
 Linux
 Solaris (Sun)

19. WebOS
 The WebOS (Web Operating System) represent
a new form of virtual operating system that
runs directly in your browser.
 The main advantages of a web operating
system is that you can access it from anywhere
but it's very arguable if it's really an operating
system or not because it runs over a browser
window and have no relation whatsoever with
the hardware and its drivers.
 You will still need an operating system to run a
WebOS.

20. WebOS
 DesktopTwo (http://desktoptwo.com)
 G.ho.st (http://g.ho.st)
 YouOS (http://youos.com)
 BrowserOS (http://oos.cc)
 eyeOS (http://eyeos.org)
