Which type of network is typically confined to a specific area, such as a building?

A Local Area Network (LAN) is designed to connect computers and devices within a limited geographical area, such as a building or a campus. This type of network allows for high-speed data transfer and is commonly used in homes, schools, and businesses to facilitate communication and resource sharing among devices.

The LAN is characterized by its ability to enable quick and efficient access to shared resources, such as printers and files, and it typically utilizes Ethernet or Wi-Fi technologies. This confined setup contrasts with Wide Area Networks (WANs), which cover larger geographical areas and may connect multiple LANs. While mesh networks refer to a specific type of network topology with interconnected nodes, and personal area networks (PANs) are even smaller networks designed for close proximity connection of personal devices (like Bluetooth-connected devices), LANs are the most common type for specific areas like buildings, making this the correct answer.
