Which term describes the ability of a service to perform its intended function over time?

Availability
Reliability
Performance
Scalability

The correct answer is: Reliability

The term that best describes the ability of a service to perform its intended function over time is reliability. Reliability refers to the consistency of a service’s performance, ensuring that it can deliver its functionalities as expected without failure. It emphasizes the service's capacity to operate correctly and effectively across a specified duration, which is crucial for maintaining user trust and satisfaction. Availability, while related, is more focused on the service's readiness for use at any given moment, rather than its consistent performance over time. Performance addresses how well a service operates, such as speed or capacity, but does not inherently cover the aspect of ongoing functionality without failure. Scalability pertains to a service's ability to grow and handle increased workload, which also does not directly relate to consistent performance over time.
