What is the purpose of a shell in computing?

• A. To manage hardware components
• B. To interpret text commands for execution
• C. To provide a graphical interface
• D. To oversee memory management

Answer: (B)

The purpose of a shell in computing is to interpret text commands for execution. A shell serves as an interface between the user and the operating system, allowing users to type commands that the shell then processes. This can include tasks such as running programs, managing files, and performing system operations through command-line input. Unlike graphical user interfaces that provide a visual interaction method through icons and menus, a shell operates through text inputs, making it a powerful tool for users who are comfortable with command-line environments. This command interpretation capability is crucial for executing scripts, automating tasks, and accessing other system functionalities efficiently. The other options focus on different functionalities that are not the primary role of the shell, such as managing hardware, providing a graphical interface, or overseeing memory management, which are typically handled by other components of the operating system.
