- Handles Logical addressing
Example: IP, ICMP

Front 41

What does ICMP stand for ?

Back 41

Internet Control Message Protocol

Front 42

What is ARP?

Back 42

Address Resolution Protocol
- resolves IP to MAC address for souce that knows IP address but not the MAC

Front 43

what does RARP stand for?

Back 43

Reverse Address Resolution Protocol
- Provides IP address from a MAC address. Basically knows MAC then finds IP

Front 44

What is a Routed Protocol?
