Logical Network Diagrams
Packet Sequencing
A way of dividing data up to transmit over the network and labeling them in the sequence they were divided to ensure that the data is reassembled in the right order
Routing Information Protocol (RIP)
A standard that outlines how routers exchange routing table data and is considered a distance-vector protocol, which means that it calculates the shortest distance between the source and destination.
Describe the functions provided by the Session layer of the OSI model.
Responsible for establishing and maintaining communication between two nodes on the network.Syncronizes the dialog between the two nodes.Determines whether communications have been cut-off and, if so, figures out where to restart transmission.Often called the "Traffic Cop"
What does a IP address identify?
A machine or group of machines
What is Balanced pair operation?
Two wires with equal and opposite signals

At ALL layers.
The primary reason for networking standards is to:
ensure that hardware and software produced by different vendors can work together
What OSI Layer deals with TCP and UDP, and is known as the post office layer?
Transport Layer/OSI Layer 4

What is the function of ARP?
ARP obtains the MAC address of a host, and then maps the MAC address to the host's IP address.

Challenge, Hash Response, Check for a match
What is the main improvement between SNMP version 1 and 2?
In v2 you can make bulk requests and receive bulk data
