I know there really isn't a centralized forum for networking concepts, so I feel that this is best suited for the "Windows Server" section. For those of you out there learning networking fundamentals, here are some helpful OSI model videos to get you better acquainted with some of the particular layers. These videos only cover 2 out of 7 layers, the Data Link Layer and the Network Layer. Feel free to post and share your favorite OSI model videos here! The Java applet isn't functioning properly and letting my add videos, and I haven't made 20 posts yet so here are the links: youtube.com/watch?v=pi7mMjiixiY youtube.com/watch?v=Bp7ft_rEZuo
