The primary function of the command interpreter is to locate and execute the following command specified by the user. Command Interpreter checks a valid command and executes that command otherwise it will throw an error.

For Operating Systems, CPU configuration algorithms are:
i) Preliminary arrival schedule
ii) Short Activity to Start Planning
iii) Essential planning
iv) Planning Round Robin
v) Editing a multi-level line
vi) Response Line Arrangement
All of these programming algorithms have their advantages and disadvantages.

Kernel is the first memory-loaded program where the OS loads and stays in memory until the OS is running. Kernel is a key component of the OS that is responsible for managing resources, allowing multiple processes to use resources and providing services across a variety of processes.

In Operating Systems, each process has its own address space that contains code, data, stack, and bulk segments or categories. Each process also has a list of files that are opened by the process as well as all alarms, signals, and various signal holders.

In a timely sharing system, when the time allotted for the process is completed, the process goes from active mode to Ready State. In a time-sharing operating system, unit time is defined by CPU sharing, called quantum time or a fraction of time. If the process takes less than 1 quantum time, the process itself will drain the CPU.

Cascading termination refers to termination of all child proceedings if the parental process ends Normally or Unusually. Some systems do not allow child processes to take place if the parental process is terminated. Cascading termination is usually initiated by the operating system.
