The network technology that connects devices to form a local area network (LAN) is typically based on Ethernet standards. Ethernet uses physical cables (like CAT5 or fiber optics) and wireless connections (e.g., Wi-Fi) to facilitate communication between devices within a limited geographic area, such as a home, office, or school. It enables data sharing, resource access, and file transfers among connected devices, providing fast and reliable communication. LAN technologies are crucial for creating secure and efficient networks in various settings.
