Week 9 UAS Flashcards
What is Dynamic Mapping?
using a protocol to create the table
why we should use physical address?
To pass through packets to its destination via the physical network
What is ARP?
Address Resolution Protocol, is a dynamic mapping method that finds a physical address given a logical address. An ARP request is broadcast to all devices on the network. An ARP reply is unicast to the host requesting the mapping
The difference between ARP and RARP?
Two protocols have been designed to per- form dynamic mapping:
Address Resolution Protocol (ARP) and Reverse Address Resolution Protocol (RARP).
ARP maps a logical address to a physical address;
RARP maps a physical address to a logical address.
What is ICMP?
The Internet Control Message Protocol (ICMP) is one of the main protocols of the Internet Protocol Suite. It is used by network devices, like routers, to send error messages indicating, for example, that a requested service is not available or that a host or router could not be reached.
