Operating System II

Examples of operating system

 Common examples of operating system

• Ms-Windows (Microsoft window):   

It is a single user GUI operating system. That is, only one person can use the system at a time.

 Versions of windows operating system:

1. Windows 95
2. Windows 98
3. Windows 2000
4. Windows ME ( millennium edition)
5. Windows XP ( Experience)
6. Windows NT ( New Technology)
7. Windows Vista
8. Windows 7
9. Windows 8
10. Windows 10

• UNIX ( A multiuser command line operating system)
• Novell Netware  (is a command-line Network Operating System)
• Linux:  A GUI/ Command line multiuser and network operating system.
• XENIX:  A Unix based multiuser operating system.
• MS-DOS (Microsoft Disk operating system):  This is a single-user operating system.

There are many different operating systems. Each does the same thing: they control all input, processing and output.

DOS (Disk Operating System) – one of the first operating systems for the personal computer. When you turned the computer on all you saw was the command prompt which looked like c:\ >. You had to type all commands at the command prompt which might look like c:\>wp\wp.exe. This is called a command-line interface.
It was not very “user friendly”

• Windows – The Windows operating system, a product of Microsoft, is a GUI (graphical user interface) operating system. This type of “user-friendly” operating system is said to have WIMP features:
  1. Windows
  2. Icons
  3. Menus
  4. Pointing device (mouse)
• macOS – Macintosh, a product of Apple, has its own operating system with a GUI and WIMP features.
• UNIX – Linux (the PC version of Unix) – Unix and Linux were originally created with a command-line interface, but recently have added GUI enhancements.

*user-friendly is a relative term. The current GUI interfaces provided by Windows and Mac operating systems are more friendly than the previous DOS systems, but still, require us to conform to their specifications (use of a keyboard or mouse instead of voice and/or handwriting recognition).
