Where are the Learner Resources that Wes keeps mentioning in CompTIA Network+ (N10-008)?
-
Learner Resources are referenced multiple times in this course, and I'm having a hard time finding them.
I've checked the show notes and downloaded the Course Files. I've been through the Course Files, and although there are things for the episode it does not show the information referenced. Looking for some help finding these resources.(BTW, ITProTV I recommend renaming files in the Course Files to be much more clear and less jumbled)
-
@A-I, I apologize you are having issues, and you tell me what episode notes you are looking for? Also, this is great feedback we have been developing and improving our processes since the recording of this episode. This helps tremendously, to improve the quality of the courses.
-
Hey @A-I, thank you for the information. I have revised the notes, PowerPoint slides, and references. We will update the site as soon as possible. Once updated, I ask you go to the Overview page and redownload the show notes. I would like to hear back from you and make sure you have the materials you are looking for!
-
Hey @A-I our team has uploaded the revised files. Please redownload them when you have the chance. Thank you for your patience, and I look forward to hearing from you.
- Note - there are a few of the IP addressing episodes that have Word docs for resources, which is slightly different than the rest of the episode files.

The reorganization of the notes looks great! It makes it so much easier to find things related to an episode. Thank you for doing that!
However, for episode Fiber Cables and Connections, I'm still not finding the specifications of the modular transceivers in the course files. I've gone through the pdf, .md, power point (individually click through each slide and looked at the notes on them), and the Word Doc.
"Now we're gonna put, transmission speeds and some of the things that you need to know about it. We'll put them in the learner resources for you. "For episode Service Provider Links the specifications are in the power point and you have to be looking for the notes of each slide. For future learners, is it possible could there be a word doc with those laid out simply?
-
Hey @A-I, yes, I can do that. You need the SFP, SFP+, QSFP....etc names/ standards, speeds and transmission media that I mentioned. There is also a need for the service provider standards, such as DSL, ADSL, SONET/SDH, PRI/BRI ISDN....etc. with the speeds, distance factors as well?
-
A great idea and we do make every attempt to point out the topics that students need to be aware of, however flashcard type definitions may not be in the show notes as we use these to move the episode forward during recording.

@A-I here is the information you needed, these will be included in the Fiber Cables and Connectors:
- Transceivers
- Small form-factor pluggable (SFP)
- 100 Mbps/ 1 Gbps
- Enhanced form-factorpluggable (SFP+)
- 10 Gbps
- Quad small form-factor pluggable (QSFP)
- 4 channels (quad)
- 4 Gbps
- Enhanced quad small form-factor pluggable (QSFP+)
- 4 channels
- 40 Gbps
- Small form-factor pluggable (SFP)
- Transceivers

@A-I here is the information you needed, and will be included in the Service Provider Links show notes (I will make a couple of posts)
- Satellite
- Speeds = 10-100 Mbps
- Line-sight communication
- Increased latency with deteriorating atmospheric conditions
- Allows communications to areas where physical cabling is restrictive
- Cable

- Data Over Cable Service Interface Specification (DOCSIS)
- Speeds
- Downloads (v3.1 - v4.0) = 10 Gbps
- Uploads (v3.1) = 1-2 Gbps
- Uploads (v4.0) = 6 Gbps

These are great! Thank you for compiling these.
I misspoke about the raw memorization. What I meant was, could you ensure that all the learner resources that you said you would put into the course file (like the things you just posted for me) are in all episodes. Meaning when I continue the course all course material will already be in the appropriate episodes, rather than having to post here and then having you update them.
