Communication and network 1/20
--Communication method (circuit switching method / packet switching method) --tcpdump command (command to see the contents of the packet) --ping command --About IP address
--How does the Internet work? How communication is actually done --TCP / UDP, IP address, etc.
――I knew ping in an internet game, but I think I understood it even more. --I learned that the IP address is about to be migrated. ――I feel that what I only knew as a word became known a little deeper.
――It wasn't difficult, it was full of things I knew but didn't know.
――It looks like a network-related class next time!
