Correct Answer - Option 2 : UNIX

The correct answer is UNIX.

  • A multi-user operating system facilitates multiple users to work on a single computer system.
  • A multi-user operating system is an operating system that allows multiple users to connect and operate a single operating system.
  • The users interact with it through terminals/computers which gives access to the system through a network or machines.
  • Example:
    • Unix.
    • Virtual Memory System.
    • Mainframe OS.
    • Windows NT.
    • Windows 2000.
    • Windows XP.
    • Windows Vista.
    • Mac OS X.

 

  • Batch user operating system:
    • In this type of operating system, the user does not interact with the computer directly.
    • There is an operator which takes similar jobs having the same requirement and divides them into batches.
  • Real-time operating system:
    • In these operating systems, the time interval required to process and respond to inputs is very small.
      • This time interval is called response time. 
  • Multi-boot operating system:
    • In a Multi-boot operating system, multiple OS is flashed into a single computer.
  • Multitasking operating system
    • The multitasking operating system provides the interface for executing multiple program tasks by a single user at the same time on one computer system.
    • For example, any editing task can be performed while other programs are executing concurrently.
    • Other example, users can open Gmail and PowerPoint same time.
