All of the mentioned
10) The first Network
CNNET NSFNET ASAPNEET ARPANET
State True/False 04
First network is ARPANET.
User datagram protocol is called connectionless because all
UDP packets are treated independently by transport layer.
In virtual circuit network each packet contains a short VC
number.
Physical, data link and network layers are network support
layers and session. Presentation and application layers are
user support layers.
