How many computer networking formats or protocols are there?
That’s like asking “How many ways can you get from the library to the post office?”. There is no limit. There may be only a few efficient ways for getting directly from the library to the post office, but if you want to go by the bank on the way, you will invent your own path. Anyone can create their own protocols. New ones are created every day and most of them are hardly ever used, or may only be used by one person. There are common ones that you hear about like FTP, SMTP, etc. For a list of those, look in the RFCs ( http://www.rfc-editor.org/rfc-index.html ). I know one of them has a list of all the protocols. Not sure what it is, but I’ll look that up and then post it here.
