What is a menu in computer applications primarily used for?

A menu in computer applications is primarily used to provide options for finding information or executing functions. In most software applications, menus serve as navigational tools that allow users to easily access various features and commands. These can include functions such as saving documents, opening files, or changing application settings.

Menus enhance user experience by organizing commands in a structured way, which helps users to locate and select tasks without needing to remember keyboard shortcuts or command input. This organization can come in the form of dropdown lists, context menus, or sidebar options, all aimed at streamlining user interactions with the software.

In contrast, other options do not reflect the primary function of a menu. For instance, executing hardware functions typically requires specific commands or settings outside the scope of standard application menus. Displaying memory usage pertains to system-monitoring tools rather than user-interface design. Similarly, controlling system settings is more related to system configuration menus or preference panels, rather than the general purpose of application menus which focus on user tasks and functions.
