What Is Application? (© All Computer Studies)

How Application Programs Work

Application programs are written in a text based computer language. Once written, they are compiled into a binary (0101) language the computer understands. The application programs use function calls (as described in the section about operating systems) to interface to the various computer peripherals such as your keyboard, mouse, scanner, printers, and other devices. Most of these function calls are provided by the operating system so the application programs are usually compiled for a specific operating system such as Microsoft Windows XP ®, Microsoft Windows 7®, or Microsoft Windows 8®.
