After finishing this chapter you are responsible for being able to describe, define, and compare these concepts:

1. Engineering Problem Goal: Devise a set of protocols to handle large amounts of digital data

> Speed : How soon will it get there? How much bandwidth is required?
> Accuracy : Will it arrive error free? How much work must be done to fix errors?
> Power : How many watts are needed to get the job done over a given distance?
> Reliability : How robust is the network to damage?
> Security: How safe is the data from unwanted inspection or tampering?
> Implementation Cost : Hardware and coding issues translate into both time and energy.
> Operating Cost: Long-term costs that must be covered and exceeded by the income generated by the network.

4. General Knowledge Required:

a. All network designs should be optimized to take into account
