Concepts Learned
Switch to port
Router to switch
Firewall to router
DNS
Redundancy
Wireless mesh
DVR capture & storage
Switch to Port
Cable runs from port to patch panel
Patch panel is labeled according to the ports
Each port on the patch panel is connected to a switch by another cord.
Router to Switch
Routes information between switches.
Resets the hop count
Information jumping from switch to switch is a hop
Hubs included in a hop
Firewall to Router
Firewall sits between internal and external networks.
Controls the flow of information between the two networks.
DNS
Domain Name System translates humanly meaningful names into numerical identifiers for network equipment.
Every domain has to have one.
Redundancy
Having backup equipment installed so that in the event that one device fails another can take over instantaneously.
Network equipment
Server power supplies
Battery backups
Wireless Mesh
A wireless communication network made up of many nodes that act as a single node.
Each node establishes a connection with another node wirelessly.
DVR Capture & Storage
A Digital Video Recorder controls when and how footage is captured and stored.
How much video needs to be readily available?
How long does the video need to be stored?
Experience
An eye opener
Experience that can not be found in the class room.
Holding your own while learning.
