I'm studying for the Net+ now and having a hard time finding some
clear info regarding the OSI model. I'm looking at Wikipedia (among several other sources, mind you) but it seems a little hard to understand I guess... For example, is the BASIS of the Transport Layer just sending information? I know it keeps records for reliability, etc, but is that right? Any help would be appreciated.

Feel free to email (or message) me if you would be willing to help me study!
Thanks!
