How does a host on an Ethernet LAN know when to transmit after a collision has occurred?

1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
3. You can improve the CSMA/CD network by adding more hubs.
4. After a collision, the station that detected the collision has first priority to resend the lost data.
5. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.

What type of RJ45 UTP cable do you use to connect a PC's COM port to a router or switch console port?

Which of the following are unique characteristics of half-duplex Ethernet when compared to full-duplex Ethernet?

1. Half-duplex Ethernet operates in a shared collision domain.
2. Half-duplex Ethernet operates in a private collision domain.
3. Half-duplex Ethernet has higher effective throughput.
4. Half-duplex Ethernet has lower effective throughput.

Why does the data communication industry use the layered OSI reference model?

1. It divides the network communication process into smaller and simpler components, thus aiding component development, design, and troubleshooting.
2. It enables equipment from different vendors to use the same electronic components, thus saving research and development funds.
3. It supports the evolution of multiple competing standards and thus provides business opportunities for equipment manufacturers.
4. It encourages industry standardization by defining what functions occur at each layer of the model.

What type of RJ45 UTP cable is used between switches?

A receiving host has failed to receive all of the segments that it should acknowledge. What can the host do to improve the reliability of this communication session?
