availability

Availability refers to the capacity of a system, service, or resource to be accessible and functional when needed. In everyday terms, it means that something—be it data, a product, or a service—is in a state where it can be used without delay. For instance, a website that is accessible for users at all times is considered highly available. Conversely, if a service frequently goes down or is difficult to reach, its availability is low. High availability is crucial for ensuring reliability and user satisfaction in both technology and general services.
