Application functions refer to the specific tasks or operations that a software application can perform. These functions are designed to meet user needs and can include activities like data entry, calculations, or generating reports. Each function contributes to the overall purpose of the application, making it more useful and efficient for users. In many applications, functions are organized into categories or modules, allowing users to navigate easily. For example, in a word processing application, functions may include spell check, formatting text, and inserting images. Understanding these functions helps users maximize the application's capabilities and improve their productivity.
