Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.

Consider the rdt3.0 protocol. Draw a timing diagram showing that if the network connection between sender and receiver can reorder messages, i.e., that two messages propagating in the medium between the sender and receiver can be reordered, then rdt3.0 will not work correctly. Referring to the diagram, clearly explain why this is the case.
Which two statements about routing protocols are true (choose 2). a) OSPF elects designed routers on multi-access links. b) RIP does not support classless routing. c) EIGRP uses broadcast traffic to establish adjacencies with its neighbors. d) RIP does not advertise a route beyond a hop count of 15. e) IBGP is an internal routing protocol.
