Question 1 Numerous Web sites are available that will test your Internet data communications speed. You can find one good at www. speakeasy. com/speedtest/.

Transmission Line Types, Uses, and Speeds Line Type Use Dial-up modem 56 Kbps DSL modem 1. 544 Mbps Telephone line (twisted pair copper lines) WAN-T 1 -Using A pair of telephone lines Coaxial cable Maximum Speed Cable modem 1. 544 Mbps Upstream to 256 Kbps Downstream to 10 Mbps (usually much less, however) Unshielded twisted Pair (UTP) LAN Optical fiber cable LAN and WAN-T 3, OC-768, etc. 40 Gbps or more WAN- OC-768, etc. 40 Gbps or more Satellite 100 Mbps

A. While connected to your university’s network, go to Speakeasy test your speed against servers in Seattle, New York City, and Atlanta. Compute your average upload and download speeds. SEATTLE: Download speed: 2. 81 Mbps Upload speed: 1. 19 Mbps � NEW YORK: Download speed: 4. 13 Mbps Upload speed: 2. 15 Mbps � ATLANTA: Download speed: 3. 55 Mbps Upload speed: 2. 08 Mbps �

Internet Speed

B. Go home, or to a public wireless site, and run the Speakeasy test again. Compute your average upload and download speeds. Compare your speed to those listed in the table. If your performancing this test at home, are you getting the performance you are paying for? SEATTLE: Download speed: 3. 29 Mbps Upload speed: 1. 36 Mbps � NEW YORK: Download speed: 3. 30 Mbps Upload speed: 1. 37 Mbps � ATLANTA: Download speed: 3. 30 Mbps Upload speed: 1. 38 Mbps �

C. Contract a friend or relative in another state. Ask him or her to run Speakeasy test against those same three cities. � SEATTLE: Download speed: 4. 32 Mbps Upload speed: 0. 29 Mbps � NEW YORK: Download speed: 6. 16 Mbps Upload speed: 0. 41 Mbps � ATLANTA: Download speed: 6. 48 Mbps Upload speed: 0. 41 Mbps

Compare the results in parts a, b, c. What conclusion, if any, can you make from these tests? � To sum up, this experiment showed us that internet speed is determined by several factors. It is not something that can be calculated just by bandwidth, or server speed. Different locations have different levels of Internet speed performance depending on the hardware they utilize, their location, and how much traffic is on them at any given time. The class book made me become more familiar with many of the fancy sounding terms that are associated with the Internet. After studying them, we are pleased to say that I am no longer lost in a conversation about dial-up speeds, and DNS servers.

Question 2 Suppose you work for a company that installs computer networks. Assume that you have been given the task of creating spreadsheets to generate cost estimates.
