A dedicated line is a network connection that isn't shared. These may be implemented using resources such as fiber optic cables that are physically shared but are logically separated with guaranteed levels of performance. Dedicated lines tend to be more secure as they can be isolated from the public internet. The following are illustrative examples of a dedicated line.
