Know the differences in how UDP sequences packets.
You need to remember that UDP does not sequence packets and is connection-oriented.
Know how the DoD model matches to the OSI Reference Model.
The DoD model contains four layers, which match up to the OSI Reference Model’s seven layers.
Remember the specifications of each protocol.
For example, you should know that TCP is a connection-oriented protocol, and UDP is a connectionless protocol.
Key Terms and Concepts
Address Resolution Protocol (ARP)
Described at the Internet layer of the DoD model, ARP is used to find a hardware address, given the IP address.
Bootstrap Protocol (BootP)
Described at the Internet layer of the DoD model, BootP is used to give diskless workstations an IP address.
IP address
Network address assigned to a node on a network. Used to send and receive packets or datagrams on an internetwork.
Internet Protocol (IP)
A connectionless protocol described at the Internet layer of the DoD model.
Reverse Address Resolution Protocol (RARP)
Described at the Internet layer of the DoD model, RARP is used to find an IP address, given the hardware address.
Subnetting
The breaking up of an IP network address into smaller networks.
Telnet
Terminal emulation program used to create a virtual window to a remote device.
Transmission Control Protocol (TCP)
A connection-oriented protocol specified at the Host-to-Host layer of the DoD model.
User Datagram Protocol (UDP)
A connectionless protocol defined at the Host-to-Host layer of the DoD model.
