LANs are cheaper than WANs, which require more cabling and often use expensive equipment like T1 lines. LANs are faster than WANs because they don't use long-distance data transfers to share information; instead, they communicate directly with each other over short distances. Lastly, LANs can be more secure because they're not exposed to remote access by Internet users like WANs are.#BBD0E0 »
