Which layer 1 devices can be used to enlarge the area covered by a single LAN segment? Switch NIC Hub Repeater RJ45 transceiver

1 only
1 and 3
3 and 4
5 only

Correct Answer: 3 and 4

Explanation:

Not that you really want to enlarge a single collision domain, but a hub (multiport repeater) will provide this for you.

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

How does a host on an Ethernet LAN know when to transmit after a collision has occurred? In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting. You can improve the CSMA/CD network by adding more hubs. After a collision, the station that detected the collision has first priority to resend the lost data. 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.
