QUESTION 8

Which of the following is false about Ethernet networks?

Ethernet is most popular LAN standard

In a bus topology Ethernet, data sent from one station can not be detected by other stations.

In an Ethernet network, all nodes sharing the same channel is said to be in the same collision domain.

Ethernet makes us of the CSMA/CD protocol for channel access

In an Ethernet network, all nodes sharing the same channel is said to be in the same collision domain.

Ethernet makes us of the CSMA/CD protocol for channel access

Explanation / Answer

a) The most widely used LAN technology is the Ethernet and it is specified in a standard called IEEE 802.3.

this is true because it is simplest and less cost.

b) In bus topology of ethernet:

this is a false statement.

All transmissions go to all the connected workstations.
Each workstation then selects the transmissions it should receive based on the address information contained in the transmission.

C)

ll nodes/devices that share an Ethernet or fast Ethernet LAN using the CSMA/CD rules are part of the same collision domain or, in other words, all the nodes/devices that are connected to a hub are part of the same collision domain. So, when a collision occurs in a collision domain, everyone in that domain gets affected.

d)true

Standard Ethernet networks use CSMA/CD to physically monitor the traffic on the line at participating stations
