What are the benefits of using fiber-optic cables in networking?
Fiber-optic cables offer high-speed data transmission and are less susceptible to electromagnetic interference compared to copper wires.
What is an SSID in Wi-Fi networks?
SSID, or Service Set Identifier, is the name of a Wi-Fi network that devices use to identify and join the network.
Explain 'network latency'.
