Today I am reviewing the first two videos in our CompTIA Network+ course. Feel free to click the link to get more information about this course.
The Instructor for the Network+ course is Chris Bryant. He is very experienced, and really does an excellent job with it. He takes a very detailed approach to explaining the content, which is important for a user who is not very familiar with the material. However, if this material is used as a review, it may be a good idea to watch the video at a faster speed, as Mr. Bryant deliberately takes his time to be very thorough.
The first video of the Network+ course deals with the idea of physical networking. This covers anything that is on the first layer of the OSI model, which is also described in detail. Mr. Bryant talks about network topologies, or how a network is physically set up and how the machines in the network connect to each other. He goes into specifics about the most common topology schemes, as well as some that are not very common anymore. The best part of this particular video is that he explains why some topology schemes are more useful than others.
In the second Network+ video, Mr. Bryant describes MAC addresses — a topic that is part of the second layer of the OSI model. He covers the logic behind MAC address numbering, how addresses are resolved by network hardware, and even adds a little tidbit about how to convert hexadecimal into decimal. I know I always have trouble with that, so it was nice to get that extra bit of advice. I think the best part of this video is the descriptions he gives of the Address Resolution protocol and Reverse Address Resolution protocol. That can be a very confusing topic, and he breaks the topic down like a pro (I guess he is one… duh) and explains it all in a very easy to understand way. I agree with Mr. Bryant when he says that his videos are worth watching multiple times to get the most out of them.
That’s all for now. Be sure to check back here for my next post.
