Which among the following is NOT a function of the Operating System?

The choice of conducting user training is not typically considered a function of the operating system. Operating systems are designed to manage hardware and software resources on a computer system, ensuring that the system operates efficiently and effectively. Their main functions include managing files and file systems, scheduling CPU time to various processes, and allocating access to input/output devices.

While user training can be important for effectively utilizing an operating system, it falls outside the core responsibilities of the system itself. Instead, user training is usually provided by institutions, instructional materials, or individual trainers who focus on helping users understand how to interact with and utilize the features of the operating system. This distinction highlights how the core functionalities of an operating system revolve around resource management rather than education or training.
