What is the purpose of a station sensing the medium for the presence of another transmission (carrier) before starting its own transmission?
What is the purpose of a station sensing the medium for the presence of another transmission (carrier) before starting its own transmission?
- To optimize the overall network throughput
- To coordinate the transmission schedule with other stations
- To ensure that the station has exclusive access to the medium
- To reduce the possibility of a collision occurring (correct)
What is the reason given in the text for why all stations immediately know when a frame is sent by a station?
What is the reason given in the text for why all stations immediately know when a frame is sent by a station?
- The propagation time in a LAN is very small (correct)
- The stations are configured to continuously monitor the medium
- The stations are equipped with high-speed network interfaces
- The stations are using a centralized coordination mechanism
What is the primary reason for avoiding transmissions that are certain to cause collisions?
What is the primary reason for avoiding transmissions that are certain to cause collisions?
- To reduce the overall network traffic
- To prevent the network from becoming overloaded
- To minimize the number of retransmissions required
- To improve the performance of the LAN (correct)
