WGU Courses and Certificates Introduction-to-IT Question # 3 Topic 1 Discussion

1.Keyboard Input:

oWhen executing a program from the command line, the keyboard plays a crucial role in providing input to the system.

oThe user types the command or program name using the keyboard, and the operating system interprets these inputs.

oThe keyboard allows the user to interact with the command-line interface (CLI) by entering commands, parameters, and options.

2.Command-Line Execution:

oTo execute a program, the user types the program’s name (or its full path) followed by any necessary arguments or options.

oThe operating system processes this input and runs the specified program.

oFor example, to run a Python script named “my_script.py,” the user would type:

opython my_script.py

3.Other Peripheral Devices:

oLet’s briefly discuss the other options:

Hard Drive (B): The hard drive is a storage device and is not directly involved in executing programs from the command line. It stores files and data but does not execute them.

Speaker ©: The speaker is an output device used for audio playback. It does not play a role in executing programs.

Printer (D): The printer is an output device used for printing documents. It is not used to execute programs.
