Why are Leased Lines considered leased lines?

Leased lines are defined by their exclusive nature of use, which makes option C misleading in this context. The term "leased line" refers to a dedicated telecommunications line that is rented or leased from a service provider by a single customer for their exclusive use. This means that the customer has a consistent and dedicated connection without the fluctuations or contention that might come with shared lines.

In reality, leased lines are typically rented by customers from telecommunications companies, allowing them to have a stable and continuous connection for their communications needs. The "leasing" aspect comes from customers paying for this dedicated service, which provides reliability and consistency in performance.

The correct understanding is that leased lines are reserved exclusively for the customer, ensuring no other users share or affect the quality of the communication on that line. This dedicated nature is what differentiates leased lines from other forms of connectivity, such as broadband connections, which can be shared among multiple users.
