What does a packet contain?

Question

The source IP, destination IP, source MAC and next router's MAC?

am I right so far? What else does a packet contain? The data itself, udp/tcp... what more?

Answer 1

Google is always available for this....

That said, there is much more to a packet, depending on what protocol you use (UDP or TCP). There's the preamble, the checksum, the source/destination addresses, the source mac, the data being sent, etc. etc.

Once again, I stress, google is always on standby....
