Leased lines are known for providing secure, dedicated, and reliable connections, with guaranteed bandwidth for data, voice, and video transmission. Because they create a direct connection between different locations, you can expect minimal latency, jitter, and packet loss. However, such high-quality service comes with a cost, as leased lines are more expensive than other connection types, like broadband or MPLS. Because costs can scale based on distance, leased lines are more feasible for organizations requiring a high level of security and performance, like financial institutions or large enterprises.
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.
