Useful for Troubleshooting a Network, Programs that do this are known as Packet Sniffers
What is Port Monitoring
These are the two standard types of ethernet cables
What are UTP and STP?
A type of topology in which a token was passed from computer to computer on the network. If you had the token, you could transmit
What is a Token Ring (not a Tolkien Ring)?

What is a Murder of Crows?
A server which provides user authentication and works with the credentials database to allow users access to a network through a switch or other initial connection point
What is a RADIUS server?

What is Fiber Optic Technology?
An error caused when two computers on a network attempt to send packets simultaneously
A networking device in which each device on the network is connected to its own port and as such, it's own collision domain
What is a switch?

What is Mace?
A redundancy method that ensures that, should a primary router or gateway fail, another is available to maintain network connection
What is first hop redundancy
These are the two main types of fiber optic cable
What are Multi-Mode and Single Mode Cables?
A Protocol used by almost all modern switches to avoid redundant links causing a broadcast storm
What is Spanning Tree Protocol?
this feature can set priority flags on packets coming through a switch to ensure high priority packets are directed first
What is QoS (Quality of Service)
He developed the incandescent light bulb

Makes multiple redundant links into one logical link to take care of congestion issues on a network
What is LACP (Link Aggregation Control Protocol)?
A device which performs Network Address Translation and is the common gateway for traffic into or out of a network
What is a Router?

What is the Venturi Effect?
Using SSH to configure a manageable switch, and connectiong off of your normal network. This is referred to as Out of Band (OOB) management.
what is Management Access and Authentication?
The standard covering all things Ethernet developed by the Intstitution of Electrical and Electronics Engineers
What is IEEE 802.3?
A topology in which all computers would listen to see if there was any transmission happening. If none was, it was free to send
