Which of the following interprets your actions when typing at the command line for the operating system?
A. Utility
B. Application
C. Shell
D. Command
Correct Answer: C
Explanation/Reference:
Explanation: The "shell" is another name for the command shell or command interpreter. This is the program that gives you a command prompt, accepts the commands you type there, and basically makes the computer do what you tell it to.
The shell’s job is to interpret your commands and run the programs you request. Linux was designed to be a multitasking operating system, which means you can run more than one program at one time. Linux was also designed as a multi-user OS, which means that you can have more than one shell running at the same time. (Each user gets his own shell at login.) As a user, you have access only to the programs you are running, not the ones other users are running (though you can run your own copy of the same program). The programs are kept separate because they are "enclosed" in a "shell".
