Lab 3

Objectives:

The objectives for this lab are to learn about the OSI model to help us better understand computer networks.

Equipment:

Personal Computer

Notes and Observations:

I first completed the background information questions. I learned the OSI model stood for open systems interconnection that was established in 1977. I created a mnemonic for the OSI model. All people seem to need data processing. I then filled out the chart for the OSI model.

Next, I completed the the questions about routers, hubs, and switches. Then, I opened command prompt and found out my IP Address and MAC address by typing ipconfig. Next, I used ARP and pinged other computers in the room and got their addresses. I then did a trace route and got 20 hops to iland.net with an IP address of 216.74.192.3.

Lastly, I used the Cisco Catalyst switch to see how data was sent and the addresses it went through.

Conclusion:

I successfully used the OSI model as a method of understanding how data is sent and received in a network as well as how to track it and use it. So far in the networking class, this lab has taught me the most and helped me develop a better understanding. 

Lab 2

Objectives: To create a working CAT5 cable using the T568B wiring standard and to use a 110 punch down tool to complete a punch panel as well as research other types of cabling.

Notes and Observations: I cut off the old RJ45 connector and followed the color order and arranged my wires and crimped the connector to the insulation and repeated the same steps for the other end. Cable was tested and worked. I then used the 110 punch down tool and arranged the wires on the punch board and terminated the connections.Thicknet cable can run up to 500 meters thinnet 185 meter. Thinnet is easier to run because its a thinner cabling and is generally cheaper than thicknet. UTP offers better crosstalk protection than thicknet and thinnet and is more cost effective than fiber optic cabling. UTP can be ran up to 100 meters. Fiber optic cabling is faster than the other types of cabling however is more expensive and is frequently used as a backbone for a large network or for long distances.

Questions: N/A

Conclusions: I successfully created a working CAT5 cable with RJ45 connectors and successfully used the punch down tool to terminate my connection on the punch board.
