d. traktante simpligojnKiu deklaro priskribas la celon de defaŭlta itinero? - Elektu unu:
a. por identigi la Tavolon 2 address of an end device on the local network.
b. to forward data to the local switch as the next hop to all destinations.
c. to transfer data to another host on the same network segment.
d. to transfer data to a host outside the local network when no other route to the destination exists. Correct
e. to send packets whose destination address is unknown - In Stop-and-Wait, deadlock can be avoided by the sender side doing retransmit-on-timeout while the receiver does not do retransmissions.
Elektu unu:
Vere
