Answer:
Scalability
Step-by-step explanation:
Scalability is a generic term for the ability of a system to accommodate expansion. A system is scalable if it is able to adapt to changes in growth - either as an increase or a decrease.
Extensibility of a system is its ability to be easily modified. In other words, the ease of scalability of a system is a measure of its extensibility.
Usability of a system is the measure of how easy it is to use the system. It is the quality of the experiences of the users interacting with the system.
Portability of a system is its ability to be used or run in diverse environments.
Reliability of a system is the ability of the system to be used without failing over a specified period of time.
Therefore, the term that best describes the scenario is Scalability.
