CHALLENGE #21: --> --> --> --> .ZUHQaPLzpYS.24@.1dcf90b3/176>Frame length of packets sent over the Internet
Question as presented to our experts:
I need some clarification -- over a WAN data is send by frames. When I think of frames I think of Ethernet II and the like. I know that Ethernet II has a frame length of 1518 bytes, but it has a small header. People have told me that the header of the frames that go over the Internet amount to 40 bytes. My question is: Are the frames over the Internet like Ethernet II and thus hold less data or are the frames greater to hold the same data, and what is the actual frame length (and max) of packets sent over the Internet?
