Computer Networking 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. 1 and 3 2 and 5 2 and 4 1,3 and 4 1 and 3 2 and 5 2 and 4 1,3 and 4 ANSWER DOWNLOAD EXAMIANS APP
Computer Networking The difference between a multiplexer and a statistical multiplexer is Statistical multiplexers need buffers while multiplexers do not need buffers None of these Multiplexers often waste the output link capacity while statistical multiplexers optimize its use Multiplexers use Time Division Multiplexing (TDM) while statistical multiplexers use Frequency Division Multiplexing (FDM) Multiplexer use X.25 protocol, while statistical multiplexers use the Aloha protocol Statistical multiplexers need buffers while multiplexers do not need buffers None of these Multiplexers often waste the output link capacity while statistical multiplexers optimize its use Multiplexers use Time Division Multiplexing (TDM) while statistical multiplexers use Frequency Division Multiplexing (FDM) Multiplexer use X.25 protocol, while statistical multiplexers use the Aloha protocol ANSWER DOWNLOAD EXAMIANS APP
