Which function of NOS involves switching the CPU time between different programs?

1. directory services

2. multitasking

3. file sharing

4. security services

The answer is (B)

Multitasking in a network operating system is the ability to execute more than one process or process at a time. Multitasking creates the appearance that multiple programs are being executed at the same time, but in reality, only one program at a time is being executed. The NOS switches the CPU time from one task or program to another in order to create the appearance that several tasks are being executed simultaneously, but in reality, only a single program is being executed
