erforráskorlátozást

Erőforráskorlátozás refers to the limitation or capping of resources available to a process, user, or system. This can manifest in various forms, such as restricting the amount of CPU time a program can use, limiting the memory it can allocate, or setting a cap on network bandwidth. The primary purpose of implementing resource constraints is to ensure fair usage, prevent monopolization of shared resources, and maintain system stability and performance.

In operating systems, resource limits are often managed through mechanisms like quotas, cgroups (control groups), or resource limits (`ulimit` in Unix-like systems). These tools allow administrators to define specific thresholds for different resource types. For instance, a web server might have its CPU usage limited to prevent it from impacting other services running on the same machine. Similarly, individual user accounts might have disk space quotas to prevent excessive storage consumption.

Resource constraints are crucial in environments where multiple users or applications share a common infrastructure. By setting these limits, it becomes possible to predict resource availability, avoid performance degradation, and enhance the overall reliability of the system. Without such measures, a single resource-intensive process could potentially starve other processes of necessary resources, leading to system instability or outright failure. The careful management of resource limitations is therefore a fundamental aspect of system administration and performance tuning.
