6062
In which scenario would a wired network be the only option?
Answer:
In an area with a lot of radio interference
In environments with high levels of electromagnetic interference, a wireless network would be unreliable, making a shielded wired network the better choice.

Why are wireless networks often "half-duplex"?
Answer:
Because devices on a Wi-Fi network must take turns to transmit to avoid collisions.
In a wireless network, all devices share the same frequency, so they use a system (CSMA/CA) to listen and wait for the channel to be clear before transmitting, which is a half-duplex operation.
6070
What is the future trend in networking?
Answer:
A continued use of hybrid networks, with wireless speeds approaching wired speeds
The future will likely see a mix of both, with wireless technologies becoming faster and more reliable, but wired connections still being important for performance and security.
