Final answer:
The operating system allows communication between the computer and the user through system messages, such as low disk space, invalid command, program not responding, and system error.
Step-by-step explanation:
An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all of the other application programs in a computer.
The operating system allows communication between the computer and the user through system messages.
Here are four examples of system messages from the computer to the operator:
- Low disk space: This message notifies the user that there is not enough storage space available on the computer.
- Invalid command: This message indicates that the user entered a command that is not recognized by the operating system.
- Program not responding: This message appears when a program stops functioning or becomes unresponsive.
- System error: This message signifies that an error has occurred in the operating system or a hardware component.
