Which of the following is not an operating system?


B. Oracle

C. Linux

D. Windows

E. Android


Answer: B. Oracle

An operating system (OS) is system software used in managing computer software, hardware resources, and also in the provision of common services for computer programs. An operating system is the intermediary existing between computer hardware and programs.

The operating system performs all the tasks in a computer system; from process management to file management, handling input and output to controlling peripheral devices. Oracle is not an operating system. Instead, it is a database management system (DBMS) and it helps users store, define, retrieve, and update the information contained in a database on demand.
