Question What is a set of rules that determines how computer communicate with each other across networks? What does a routed protocol allow the router to forward? Which protocol requires only a network number because it uses the host's MAC address for the host number? What is obtained by ANDing? Why are network masks used?

What protocol is connectionless, unreliable, and is considered a besteffort delivery method? What is another term for packets? What are Layer 2 data units used for? What address is changed when a frame is received at a router interface? What does a router do with a frame that is NOT addressed to the router interface or is NOT a broadcast? What does HELN stand for? How many bits of an IP packets are reserved for the source and destination IP address? What Layer does routing? What information is used to determine where to send packets? What are values used in determining the advantage of one route over another? What are 3 routed protocols?

Answer

Protocol

allows the router to forward data between nodes on different networks IPX

The network address To allow groups of sequential IP addresses to be treated as a single unit. IP / Internet Protocol Datagrams To determine local addressing. The destination MAC address The frame is discarded IP header length 32 bits each Layer 3- Network Layer Routing tables Routing metrics 1. IP 2. IPX/SPX 3. AppleTalk
