Would it be possible for the user to develop a new command?

Would it be possible for the user to develop a new command?

Ans: Yes. 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).

Would it be possible for the user to develop a new command interpreter using the system-call interface?

Yes, it is possible to develop a new command interpreter using the system-call interface on those OS’s where the interpreter is not tightly integrated into the system (i.e., most operating systems other than Windows.) The Unix family of operating systems provides multiple command-line interpreters (sh, bash, csh, etc.)

What is the purpose of the command interpreter why is it usually separate from the kernel?

Why is it usually separate from the kernel? Answer: 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.

How do user programs and system services interact in a microkernel architecture?

User programs and system services interact in a microkernel architecture by using interprocess communication mechanisms such as messaging. These messages are conveyed by the operating system. In Unix systems, a fork system call followed by an exec system call need to be performed to start a new process.

Is command interpreter separate from the kernel?

Answer: 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 the purpose of the command interpreter?

A command interpreter allows the user to interact with a program using commands in the form of text lines. It was frequently used until the 1970’s. However, in modern times many command interpreters are replaced by graphical user interfaces and menu-driven interfaces.

What is the purpose of command interpreter?

What is the purpose of command interpreter system in operating system?

Answer: A command interpreter is the part of a computer operating system that understands and executes commands that are entered interactively by a human being or from a program.

What is the main advantage of the microkernel approach to operating system design How do user programs and system services interact in a microkernel architecture?

One benefit of the microkernel approach is ease of extending the operating system. All new services are added to user space and consequently do not require modification of the kernel. The microkernel also provides more security and reliability, since most services are running as user — rather than kernel — processes.

How microkernel differs from user programs and system services?

But in a microkernel, the user services and kernel services are implemented in different address spaces. The user services are kept in user address space, and kernel services are kept under kernel address space, thus also reduces the size of kernel and size of an operating system as well.

What is a scheduler What is a dispatcher?

SCHEDULER. Definition: Dispatcher is a module that gives control of CPU to the process selected by short term scheduler. Scheduler is something which selects a process among various processes.
