Is IP actually encapsulated in PPP, or is PPP and IP sent out at the same
time at different protocol layers? Kinda holding hands in a sense to each
other.

christopher,
it is called tcp/ip because the encapsulation was read left to right
so, for example:
smtp/tcp/ip
telnet/tcp/ip
ftp/tcp/ip
http/tcp/ip
and
ip/ppp/ethernet
ip/ethernet
ip/ppp/dial-up
ip/ppp/dsl
and so on
the ordering is arbitrary, of course - we just picked "higher level
protocol to the left"
as in "higher order bit to the left" as a way of presenting the protocol
layers.

Why do they call it TCP/IP ? that sound reversed. it should be
IP/TCP-UDP as that makes sense in
