Which among the following is NOT an example of an Operating System?

This question was previously asked in

RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)

MS Office

LINUX

UNIX

WINDOWS

The correct answer is

MS Office

Understanding Operating Systems

An Operating System (OS) is essential system software that manages a computer's hardware and software resources. It acts as the foundation upon which other applications run.

Analyzing the Options

We need to identify the option that is NOT an Operating System:

LINUX: This is a well-known open-source Operating System kernel and a family of related operating systems.
UNIX: This is another influential family of multitasking, multiuser operating systems.
WINDOWS: This is a widely used graphical Operating System developed by Microsoft for personal computers.
MS Office: This is a suite of productivity application software, including programs like Word, Excel, and PowerPoint. It runs *on* an operating system, but is not an OS itself.

Conclusion: Non-Operating System Software

Comparing the options, LINUX, UNIX, and WINDOWS are all core Operating Systems. MS Office serves a different purpose as application software.

Therefore, MS Office is the correct answer as it is not an Operating System.
