Dream Big, Dare to Fail
PPP = a protocol for running TCP/IP over serial lines. As "robust" as communicating
over coax or twisted pair, as long as you have good modems and phone lines.
SLIP = another protocol for running TCP/IP over serial lines. An older protocol
than PPP (I think), and not as "standard". To be avoided if PPP is an option.
SLIP/PPP = SLIP with built-in PPP. Can work, but will make you old before your
time getting it to work well.
UUCP = the Unix to Unix Copy Program. A method of transferring files (often
email) over (possibly slow) connection, including a PPP link. Can be used
with TCP/IP for a "store and forward" email connection. Fairly robust protocol,
still in wide use.

Not necessarily reliable. The TCP/IP suite includes a number of
different protocols for different tasks; like UDP, which is unreliable,
and TCP, which is reliable.

PPP is more than that; it's an encapsulation method that allows
virtually any network protocol, not just IP, to run over async and sync
serial connections.

Quite a bit older than PPP, and quite IP-specific. It's just raw IP
frames in a simple encapsulation.

Huh? "SLIP/PPP" is just another term for "any generic serial network
interface." Basically, it is used when you need to talk about point-to-
point lines without specifying a particular protocol.

*Real* UUCP protocol is a batch-mode file transfer protocol for Unix
systems. It's something like kermit in flavor, but much, much more
automated. It's not at all a conventional networking protocol like
TCP/IP, AppleTalk, or IPX. (Though, confusingly, you can run UUCP
protocol *over* TCP.)
