A computer system resource is any hardware or software aspect of limited availability that is accessible to a computer system. Like any resource, computer system resources can be exhausted, and issues arise due to scarcity.

Resource management, a key aspect of designing hardware and software, includes preventing resource leaks (not releasing a resource done with it) and handling resource contention (when multiple processes want to access the same resource). Computing resources are used in cloud computing to provide services through networks.
