Feedback: AN OS provides all the most fundamental features of a computer, at least from a software point of view. An OS enables you to use the computer's hardware devices, it defines the user interface standards, and it provides basic tools that begin to make the computer useful.

Q: What do we mean by the term "shell"?
Feedback: A Unix shell is a command-line interpreter or shell that provides a traditional user interface for the Unix operating system and for Unix-likesystems. Users direct the operation of the computer by entering commands as text for a command line interpreter to execute or by creating text scripts of one or more such commands.

Q: Why do we use the command line?
Feedback: A command-line interface is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines). The interface is usually implemented with a command line shell, which is a program that accepts commands as text input and converts commands to appropriate operating system functions. Command-line interfaces are often preferred by more advanced computer users, as they often provide a more concise and powerful means to control a program or operating system.
