Desktop software refers to applications designed to run on a personal computer or workstation. These programs are installed directly on the computer's operating system, allowing users to perform various tasks such as word processing, graphic design, or data analysis. Common examples include Microsoft Word, Adobe Photoshop, and Excel. Unlike web-based applications, desktop software does not require an internet connection to function, making it accessible anytime after installation. Users typically interact with these programs through a graphical user interface (GUI), which includes menus, buttons, and icons for easy navigation and operation.
