Correct Response: A. Since a wired LAN operates over dedicated copper cables, the transmission is extremely reliable. In contrast, a wireless LAN operates through the air where there are many opportunities for interference from other wireless transmissions, electrical devices, and physical obstacles. Hence lost data packets are more common in a wireless LAN. B is incorrect because a wired LAN is less difficult to secure and monitor. C is incorrect because the two types of LANs are equally vulnerable to power outages. D is incorrect because, while both are susceptible to infections, wireless LANs are more vulnerable.
