Applications can range from simple utilities, such as calculators and weather forecasters, to complex software suites for productivity, entertainment, communication, or specialized purposes. They are typically installed and executed on computers, mobile devices, or other electronic devices, enabling users to interact with them to accomplish various goals or objectives. Applications can be developed for different operating systems, such as Windows, macOS, iOS, Android, and web browsers, and they can be distributed through various channels, including app stores, websites, and enterprise distribution platforms.
