Easy Access to Data

Local Area Networks (LANs) are used for data, video, and voice transmission within a single closed location. They can connect anywhere from a few to hundreds of computers, servers, printers, and other devices. This internal network is bounded by a router, through which users access external networks, such as the internet. A local area network can consist of wired infrastructure (cable connection), wireless infrastructure (Wi-Fi), or a combination of both.

When designing LANs, it is important to consider not only throughput and reliability but also security against both unauthorized external access and risky behavior by internal users.
