No. All commands are executed in userspace. If the command is not built-in to the shell, it will look in a binary directory (/sbin, /bin, /usr/bin, or /usr/local/bin) for a program matching that name.

What is the difference between internal and external commands in MS-DOS?
INTERNAL COMMANDSThese are those commands which are contained in command.com files of MS-DOS.These are those functions that are built into the command interpreter.There is no need of any external file in computer to read internal MS-DOS command.These commands can be used as long as DOS is running on the system.Internal commands do not vary from system to system.These are ver, time, del, md, cd, copy con, cls, date, vol, ren, copy etc.EXTERNAL COMMANDSThese are those commands which are not in-built in MS-DOS.External commands are those which are not included in the interpreter.There is a need of an internal file in the computer to read external MS-DOS command.External command may vary from system to system. This means any two computers with same version of MS-DOS may have same internal commands, but may have different external commands.These are tree, xcopy, diskcopy, more, print etc.
Is the kernel in a unix os a program?
The kernel is the central control program of Unix and the majority of other operating systems.
Explain delcaring a method in java?
A method is a group of commands that are executed when you invoke, or call, the method. It is often called a "function", a "procedure", a "subroutine" in other languages; but in OOP environments, the name "method" is used instead.
Explain different layers of UNIX operating system Also explain interaction between shell and kernel using any suitable command?
Layers of UNIX Operation System along with an example to illustrate the interaction between shell and Kernel.The UNIX operating system is made up of three parts: the kernel, the shell and the programs.The kernelThe kernel of UNIX is the hub of the operating system: it allocates time and memory to programs and handles the filestore and communications in response to system calls.The shellThe shell acts as an interface between the user and the kernel. The shell is a command line interpreter (CLI). It interprets the commands the user types in and arranges for them to be carried out. The commands are themselves programs: when they terminate, the shell gives the user another prompt ($ on our systems).The programsA program is refereed to as a process while the kernel is running it. The Kernel can run the same shell program(or any other program) simultaneously for many users on a Unix System, and each running copy of the program is a separate process. The Shell is also a program that the UNIX Kernel runs for the user.As an illustration of the way that the shell and the kernel work together, suppose a user types rm myfile(which has the effect of removing the file myfile). The shell searches the filestore for the file containing the program rm, and then requests the kernel, through system calls, to execute the program rm on myfile. When the process rm myfile has finished running, the shell then returns the UNIX prompt $ to the user, indicating that it is waiting for further commands.- Submitted by SRKStudent of NIITContact No. : +91-9534330837Email: shoaibrazakhan@gmail.com
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 commands found with the Align commands evenly space objects horizontally or vertically relative to each other or the slide?

What term is used for a bundling of the Linux kernel along with other software?
a distribution.
Where the kernel reside in computer and what is it?
The kernel resides in your OS of the computer. the kernel has one main function that is to act as translator from applications to your CPU, Memory, and various other devices. In the world of Microsoft it's a go between for applications and the device drivers. In Linux, Mac OS, and, any other Unix based OS the kernel directly talks to the hardware with out the need for device drivers. For more info see the related link
What is the kernel of an operating system?
The kernel is the essential center of a computer operating system the core that provides basic services for all other parts of the operating system. A kernel is designed to be a central core to the operating system - the logic that manages the resources that the hardware has to offer.
What are the other examples of a kernel sentence?
A kernel sentence is a simple declarative construction with only one verb. Examples:We're having soup.Tony came home.Tulips are in season.He parked the car.
What does it mean to tune your Linux kernel?
If u r not satisfied with the available applications or other resources that come with the kernel, then u can modify them according to ur convenience. Add , modify or delete as you wish. This is done to ensure complete satisfaction to the user. This is called tuning of the kernel.
What is a kernel?
The central module of an operating system. It is the part of the operating system that loads first, and it remains in main memory. Because it stays in memory, it is important for the kernel to be as small as possible while still providing all the essential services required by other parts of the operating system and applications. Typically, the kernel is responsible for memory management, process and task management, and disk management. The definition of kernel is "the portion of an OS (Operating System) that is responsible for interacting with the hardware. It is the operating system software that runs in kernel mode on the computer's processor and which provides low-level intelligence for the operating system. In other words, the kernel is the "heart" of an operating system.
