Computer resources are the components and capacities that a computer system can allocate to programs, tasks, and users. They include hardware resources such as central processing units (CPUs), memory, storage, and input/output devices, as well as network bandwidth. Software resources such as file handles, process tables, and database connections are managed by the operating system or runtime environment. In virtualized and cloud environments, resource definitions extend to virtual CPUs, virtual memory, quotas, and isolated resource pools.

Resource management aims to allocate these resources efficiently, fairly, and predictably. Operating systems schedule CPU time, manage memory with paging and caching, and arbitrate access to I/O devices. Virtualization and containerization introduce abstraction layers that allow multiple workloads to share hardware while enforcing limits and quality of service. In cloud settings, resource pools and autoscaling further adapt capacity in response to demand.

Monitoring and accounting track usage with metrics such as CPU utilization, memory consumption, disk I/O throughput, network bandwidth, and latency. These measurements support performance tuning, capacity planning, and billing in managed services.

Common challenges include contention for scarce resources, starvation, performance interference between workloads, and complexity of scheduling in multi-tenant environments. Techniques such as quotas, prioritization, resource contracts, and quality-of-service guarantees help mitigate these issues.
