Please help, this is for my Technologies Infrastructure and Architecture class.

Computers communicate according to protocols that govern how they exchange information. Give an example of a protocol from your day-to-day life that governs your interactions with someone or something. Why do you think two computers might require a predefined protocol to communicate over a network? Why are standards important for these communication protocols? Do you think it possible for two computers to implement a standard protocol differently and still communicate? List the available residential access technologies in your neighborhood. For each type of access, what is its advertised downstream rate, upstream rate, and monthly price? Dial-up, cable modems, DSL, fiber, and cellular networks are all used for residential access. For each of these technologies, what is the range of transmission rates they provide? Are these rates shared or dedicated? Is the downstream/upstream symmetric or asymmetric? Describe a situation in which a symmetric upstream/downstream access technology might be desired. When might asymmetric upstream/downstream access be acceptable
