- Rationale: An IP address identifies devices on a network
and allows them to communicate.
9. A ________ is a software application that provides a user
interface to interact with the operating system and other software.
- ANS: Graphical User Interface (GUI)
- Rationale: A GUI allows users to interact with software
through visual elements like icons and buttons.
10. ________ storage refers to data storage that is not directly
accessible by the CPU and requires specific commands to access.
