Sincere Topologies
The physical layout of the media, nodes, and devices on a network.
What is a physical topology?
We tend to use pneumonics to remember multi-stage processes. Give an example of how you remember the OSI Model layers.
What is Paris Doesn't Need Trains Since Paul Arrived? (example)

What is a patch cable
What is the location where the internet connects with the corporate or local network?
What is the Entrance Facility
What Organization oversees national efforts to understand, manage and reduce risk to our cyber and physical infrastructure?
What is the CISA?
A characteristic of network transmission that reflects the way in which data is transmitted between nodes, including how access to the network is controlled and how specific resources are shared on the network
The sixth layer of the OSI model. Protocols in this layer are responsible for reformatting, compressing, and/or encrypting data in a way that the application on the receiving end can read.

what are Black Hat, White hat, and gray hat hackers?
A type of network in which several nodes are directly interconnected and no single node controls communications on the network.
What is a mesh topology?
This layer bridges the Physical layer’s networking media with Network layer processes.
What is Data Link?
This cable has a maximum distance of 100m. It is used to connect the wall jack to a the data room
What is horizontal cabling.
Where the provider's network ends and the organization's begins.
What is the demarcation point
What are the 3 most common cyber-attacks?
What are phishing, malware, and Man-in-the Middle?
A topology in which a single cable connects all nodes on a network without intervening connectivity devices.
What is a bus topology?
The fifth layer in the OSI model. This layer describes how data between applications is synced and recovered if messages don’t arrive intact at the receiving application.
What is the Session Layer?
What should you always leave extra of when running cables?
What is slack

When was the first network created and by whom?
When is 1969? Who is ARPANET?
A physical topology that combines characteristics of more than one simple physical topology.
What is a Hybrid topology?
The third layer in the OSI model. This layer, sometimes called the Internet layer, is responsible for moving messages between networks.
What is the Network Layer?
What type of panel organizes and connects lines?
What is a patch panel.
What material thing holds up network equipment?
