Module Three Overview
Lessons Learned in Module Three
The focus of Module Three was on both wired and wireless networks and their technologies. The first assignment on broadband technologies and includes an examination into DSL, cable modem, and fiber media based on vidoes from Eli the Computer Guy. The assignment covering WAN technologies focused on learning from videos by Professor Messer, and focused on specific details about various types of WAN media and speeds, as well as information about packet and circuit switching. The next assignment returns to Eli the Computer Guy's videos covering the topic of physical network segmentation, which explains concepts such as demarcation points, IDFs, and MDFs. The most personally useful assignment of the module, the Wireless Assignment will be detailed in the learning artifact below.
These assignments were vital to a futher understanding of wired and wireless network technologies. Learning specific details such as speed, media limitations, and types of topologies will be extremely useful when constructing my own networks or working on others in my career.
Learning Artifact
In the Wireless Assignment, I watched a series of tutorials from Professor Messer to went into more detail about network types and wireless networking. Learning more about network types included information about DSL, modem, and satellite Internet, as well as smaller scale networks like Bluetooth. The Wireless Networking segment introduced the IEEE family of standards for wireless networking, the 802.11 family, with specifications about speed, throughput, frequency, and range. A table detailing this information can be seen below. This information is crucial when understanding the type of standard to utilize depending on the size and capacity of your network.
| 802.11a | 5 GHz | 54 Mbps | 35 meters |
| 802.11b | 2.4 GHz | 11 Mbps | 38 meters |
| 802.11g | 2.4 GHz | 54 Mbps | 100 meters |
| 802.11n | 5 GHz and/or 2.4 GHz | 600 Mbps | 300 meters |
