System requirements are the specifications that a computer or device must meet to run a particular software application or operating system. These requirements typically include details about the necessary hardware, such as the processor speed, amount of RAM, and available storage space, as well as software prerequisites like the operating system version. Understanding system requirements is crucial for users to ensure compatibility and optimal performance. For example, a game may require a specific version of Windows and a certain type of graphics card to function properly. Meeting these requirements helps prevent issues like crashes or slow performance.
