Guide on Leased Lines for Comptia Network+ Exam

What are Leased Lines?
Leased Lines are dedicated telecommunication lines that provide constant, high-quality internet service. These lines are essentially rented out to businesses who wish for a constant, dependable network connection that doesn't fluctuate with the amount of users.

How do they work?
Leased Lines work by connecting two locations directly, irrespective of how far they are from each other. This ensures that the connection remains strong and uninterrupted. They are a form of symmetric telecommunications line, which means data can be sent and received at the same bandwidth.

Importance of Leased Lines
Leased Lines are important because they provide a reliable, high-speed internet connection. This can be critical for businesses that require a constant connection for their operations. Moreover, because the line is exclusive, businesses do not have to contend with network congestion that can happen on shared lines.
