Single-platform software is specifically designed to run on only one type of operating system or platform. iMovie is an example of single-platform software because it is developed by Apple Inc. and is designed to function only on macOS and iOS devices. On the other hand, VLC Player is designed to work across multiple platforms, thus it is not exclusive to a single operating system. Similarly, Google Chrome and Microsoft Office are also available for various platforms, making them cross-platform software, not single-platform.
