<human>:  What is the difference between a leased line and a dedicated line?
<bot>: The main difference between a leased line and a dedicated line is that a leased line is a contract between two parties, usually a service provider and a customer, that allows the customer to rent a line from the provider to use exclusively for their own use, while a dedicated line is a network connection that is dedicated to a single user or organization and not shared with anyone else. Another difference is that leased lines tend to offer higher bandwidth and have slightly higher costs than dedicated lines.
