disk quota

A disk quota is a limit set by an administrator on how much storage space a user or group can use on a computer or network. It helps manage resources by preventing any one user from consuming excessive space, ensuring fair access for everyone. When a user approaches or exceeds their quota, they may be unable to save more files until they delete some, request an increase, or permissions are adjusted. Quotas help maintain system performance and organization, especially in shared environments like workplaces or educational institutions.
