Concepts:

OSI Reference model - Be able to give a short description of what each layer in the OSI reference model does (you do not need to memorize the seven layers in order, just be able to describe what each layer does.) Also be able to give examples of actual protocols that are at each of the layers and describe how the layers are a "model".

Describe the different Ethernet protocols and how to interpret the numbers and letters in each name--such as "10BaseT", "100BaseFx". Describe the different type of media that Ethernet may use (Cat5, Fiber,...)

Describe the difference between a hub and a switch. Also describe what a router is.

Describe where the name "cell" phones comes from. How are the cells arranged? How large are they generally? How and why are cell sometimes sub-divided? What determines how many simultaneous calls can be made in a cell?

Describe three different protocols and media used to network the machines in a house.

Describe what TCP ports are. How are port numbers related to higher level protocols such as SMTP and HTTP? Describe how the college limits the amount of traffic on different ports.

Describe what sockets are from a programming standpoint. What are sockets used for and at what protocol layer do they work? What type of addresses are used in socket?

Describe some security measures that should be done to protect network security, including wireless networks.

Describe peer-to-peer file sharing protocols and how they work. How are today's P2P protocols, such as gnutella, different from older protocols such as Napster?

Describe what the electro-magnetic spectrum is and what uses this spectrum. Describe how the FCC controls what portions of the spectrum are used for different activities.

Describe how addressing works on the internet. How is a name such as www.css.edu translated into an IP address. How do machines know where to send packets that contain a particular IP address? How are IP addresses assigned and why do all machines at CSS have a address starting with 143.110...
