I am a networking student, and I am learning about the OSI system for networks. The concepts for this system are all pretty complicated, but the main issue that I'm having is the main differences between the Networking Layer and the Transportation Layer.
In the video I was learning from (the Comptia Network+ videos on Cybrary), the instructor stated in the Networking Layer video that the main purpose of the Networking Layer is to split data into packets and send it across Networks. In the Transportation video, he says that the Transportation Layer is for creating packets as well. What are the differences between these two layers? I'm very confused, any help would be greatly appreciated.
