Class Notes

1. What is Convergence?
   1. Different types of computerized systems used to be "siloed" in their own environments.  They used different types of cable and protocols for communications.
   2. Convergence allows different types of devices to use standard computer networking components and protocols
   3. By using Convergence different types of systems can now talk to each other
2. Power Over Ethernet provides power for devices over Cat5 cable
   1. Either the Switch or a Power Over Ethernet Injector is used to provide power
3. Quality of Service allows you to prioritize the importance of network traffic
4. Parallel Networks are used when you are concerned one type of network equipment will degrade the performance of other equipment.  An example is putting VoIP on it's own LAN to prevent file traffic from causing jitter.
5. Engineers are trying to make devices more intelligent so that less data is put on the network.  By making devices more intelligent less communication has to occur with main servers.
