Final answer:
A LAN is a network for connecting computers in a localized area, such as a school where it enables resource sharing and communication.
Step-by-step explanation:
A Local Area Network (LAN) is a network that connects computers and devices in a limited geographical area such as a home, school, computer laboratory, or office building. The defining characteristics of LANs, in contrast to Wide Area Networks (WANs), include their smaller geographic range and the absence of the need for leased telecommunication lines.
An example of a LAN would be the network used in a school to connect all the computers in the classrooms, computer labs, and administrative offices. This allows for the sharing of resources such as printers, file servers, and internet access, facilitating communication and collaboration among students and staff within the school premises.
LANs are characterized by higher data transfer rates and lower latency compared to WANs, making them ideal for this type of close-quarters communication and resource sharing.
