Recently passed 902 to complete my A+ cert, jumping right into Network+. I am familiar with the OSI model just from my own research while consuming the A+ material, but it appears that this is going to be a big thing for Network+. In the very first episode of Network+, Wes is going over some details about the layers and says "So if this doesn't make sense, it would be a good time to check out the OSI and TCP/IP episodes that we do have so that you guys will be aware of that."
So my initial question was where is the OSI episode located, but I just paused from typing this to skim through the episodes and I see that it is toward the bottom. This leads me to another question, however. With the A+ material, I consumed the episodes in order and felt that we were guided to consume them in order. Should we be consuming Network+ in a different order? I am definitely going to take Wes's advice and watch the OSI model video and then come back to the beginning, but what if the OSI model video contains info that I need previous episodes to understand? It seems that the OSI model videos perhaps should have been the first. Wes, let me know if I should listen to video version of Wes, or if I should continue consuming the course in the order it is presented. Thanks!
