Why is command interpreter usually separate from the kernel?
The command interpreter is usually separate from the kernel in case it fails. Either the interpreter or kernel could fail independently without affecting each other.
What is the purpose command Interpreter and why it is usually separate from the kernel?
It reads commands from the user or from a file of commands and executes them, usually by turning them into one or more system calls. It is usually not part of the kernel since the command interpreter is subject to changes.

What is a command interpreter and why is it separate from the kernel?
A command interpreter is an interface of the operating system with the user. The user gives commands with are executed by operating system (usually by turning them into system calls). The main function of a command interpreter is to get and execute the next user specified command. Command-Interpreter is usually not part of the kernel, since multiple command interpreters (shell, in UNIX terminology) may be support by an operating system, and they do not really need to run in kernel mode. There are two main advantages to separating the command interpreter from the kernel. 1. If we want to change the way the command interpreter looks, i.e., I want to change the interface of command interpreter, I am able to do that if the command interpreter is separate from the kernel. I cannot change the code of the kernel so I cannot modify the interface. 2. If the command interpreter is a part of the kernel it is possible for a malicious process to gain access to certain part of the kernel that it showed not have to avoid this ugly scenario it is advantageous to have the command interpreter separate from kernel
Why is command interpreter not a part of operating system?
It is usually not part of the kernel since the command interpreter is subject to changes.
Would it be possible for the user to develop a new command interpreter using the system call interface provided by the operating system?
It reads commands from the user or from a file of commands and executes them, usually by turning them into one or more system calls. It is usually not part of the kernel since the command interpreter is subject to changes. An user should be able to develop a new command interpreter using the system-call interface provided by the operating system. The command interpreter allows an user to create and manage processes and also determine ways by which they communicate (such as through pipes and files). As all of this functionality could be accessed by an user-level program using the system calls, so it should be possible for the user to develop a new command-line interpreter.

Where does the program python run?
Python is a runtime interpreter. It usually runs on the web server.
State the purpose of layering in networks?
The purpose of ayering is to separate functional components that interact in some sequential and hierarchical way, with each layer usually having an interface only to the layer above it and the layer below it.
