System calls are used whenever a program needs to access a restricted resource, eg a file on the hard disk, any hardware device, or when it needs to print or draw to the screen
The software needed to run a computer is known as the Operating System. Many hardware platforms allow you to choose between multiple operating systems to suit your needs.

A system call is needed for inter-process communication (IPC) between cooperating processes because it provides a controlled interface for processes to request services from the operating system. This ensures that communication is managed safely and efficiently, allowing processes to share data, synchronize their actions, and exchange messages without directly accessing each other’s memory. By using system calls, the operating system can enforce security, manage resources, and maintain stability in a multi-process environment.
Both are software, operating system is software that will make your computer boot up and run. while Application software is a program that will run on a functional operating system.
when a process or anything makes a system call ,it goes in kernel(operating system).
A "System call" you be a function accessible from a programming language to the base hardware of the computer (eg to get the time).
System calls provide an interface between the process an the operating system. System calls allow user-level processes to request some services from the operating system which process itself is not allowed to d

Service packs.
Shell Programs
System Software is the information needed to run the system. like config files and your O.S. (operating system).
No there isn't. You can still access the Command Line through the various Windows operating systems, if there is anything needed to be done that way.
