A
Q846: What is the main difference between CSMA/CD and CSMA/CA?
- A: CSMA/CA tries to avoid collisions rather than detecting them
- B: CSMA/CA detects collisions and retries immediately
- C: CSMA/CA allows unlimited transmissions without restrictions
- D: CSMA/CA uses encryption to protect messages

Q847: What is the hidden terminal problem in wireless networks?
- A: A situation where machines cannot detect collisions due to signal interference
- B: A problem where machines are too close to each other
- C: A situation where the central AP fails to function properly
- D: A problem with physical hardware malfunctions

A
Q848: How do some WiFi networks solve the hidden terminal problem?
- A: By requiring machines to send a request message to the AP before transmitting
- B: By limiting the number of machines on the network
- C: By using higher frequency bands
- D: By encrypting all transmitted messages
View Answer
A
Q849: What does a machine do if it finds the communication channel busy during CSMA/CA?
- A: It waits for a randomly determined period before trying again
- B: It immediately retries the transmission
- C: It abandons the message and does not retry
- D: It notifies the central AP of the busy channel
View Answer
A
Q850: When a machine sends a request message to the AP, what is the next step if the AP acknowledges the request?
- A: The machine can safely transmit its message
- B: Wait for another request from the AP
- C: Abandon the message and try later
- D: Retry sending the request until it is acknowledged
