1) You have been asked to design a LAN with operation over a distance of about 100m. Compare and contrast twisted pair cable, coaxial cable, fiber-optics, and wireless for this application. You should create a table or flow chart which would facilitate choosing between these options depending on circumstances. The table or flow chart should be submitted as part of your document. You may not submit a separate file
Unshielded twisted pair

Conductor Type TC CCS
Maximum Segment Length(Thicknet) 500m
Min. Bandwidth (Mhz*Km): 200/500
Cost: Relatively inexpensive
Velocity Ratio 666

2) Rank the following five media examples in order from highest data transmission speed to lowest data transmission speed: twisted pair, coaxial cable, fiber-optic cable, microwave, and satellite. 3)
b) Fiber Optic
c) Coaxial cable
e) Twisted pair
4) An entrepreneur is interested in establishing her own world-wide satellite radio infrastructure and has requested your help. Describe and justify the infrastructure that you would develop. Be sure to include the number of satellites needed, the orbits employed for those satellites, and the type and frequency of transmission utilized. a) She will need a multiplexed Earth station satellite system. The ground station accepts input from multiple sources and in some fashion interweaves the data streams, either by assigning different frequencies to different signals or by allowing different signals to take turns transmitting. With frequencies about 2-4 GHz
5) A typical signal sequence in a synchronous connection contains a significant amount of information in addition to just the intended message or data. Identify each of the blocks commonly employed and utilize an analogy to sending a physical package to explain what each block does. a) An analogy of this type of connection would be the transmission of a large text document. Before the document is transferred across the synchronous line, it is first broken into blocks of sentences or paragraphs. The blocks are then sent over the communication link to the remote site. With other transmission modes, the text is organized into long strings of letters (or characters) that make up the words within the sentences and paragraphs. These characters are sent over the communication link one at a time and reassembled at the remote location.
6) For the network that you have chosen to characterize for this class, identify the primary types of media employed. Be sure to include both how the computers individually connect into the network devices as well as how network devices interconnect and how the connection to the Internet is achieved. Briefly explain the purpose in the network of each type of media employed and identify at least one alternative media which could also fulfill this purpose.
a) The network that I have chosen for this class is a Peer to peer network. I will have four computers, one printer/copy/fax machine, and they will be connected with an Ethernet cord and through a local area network. This network is designed for a small business office.
