System requirements are the specifications that a computer or software program needs to function properly. They include both hardware and software components, such as the type of processor, amount of memory (RAM), and operating system version. Meeting these requirements ensures that the application runs smoothly and efficiently. When installing a program, users should check the system requirements to avoid performance issues or crashes. For example, a game might require a specific graphics card or a certain amount of free disk space. Understanding these requirements helps users make informed decisions about upgrades or purchases related to their computer systems.
