Desktop software refers to applications designed to run on a personal computer or laptop. These programs are installed directly on the device'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, although some features may benefit from online access. Users typically interact with these programs through a graphical user interface (GUI), which includes menus, buttons, and icons for easy navigation and operation.
