System compatibility refers to the ability of different software and hardware components to work together effectively. This means that a program designed for a specific operating system, like Windows or macOS, should function properly without errors when installed on that system. Compatibility ensures that users can run applications, connect devices, and share data seamlessly. In addition to operating systems, system compatibility also involves hardware components, such as printers, graphics cards, and motherboards. For example, a printer must have drivers that are compatible with the user's operating system to print documents correctly. Ensuring compatibility helps prevent issues and enhances overall performance.
