RRB NTPC 2019 CBT 1 Question Paper PDF (31-Jan-2021) (Shift 1)

Java

Mint

MS DOS

Ubuntu

The correct answer is

Java

Operating System Identification

The question asks to identify which option is not an operating system (OS). An operating system is system software that manages computer hardware and software resources.

Confirming Operating Systems

Let's examine the options provided:

Mint: This is a popular Linux distribution, which functions as an operating system.
MS DOS: Stands for Microsoft Disk Operating System, a widely used OS from Microsoft's past.
Ubuntu: Another well-known Linux distribution, serving as a complete operating system.

Identifying Non-Operating Systems

Java is fundamentally different from the others. It is a programming language and a platform used to develop and run applications, not an operating system itself.

Conclusion

Therefore, Java is the item listed that is not an operating system.
