This is why real-time applications like games and video use UDP.
It's sad to seen when software developers don't understand the
differences, and think UDP is "faster", and end up re-implementing TCP
error correction over UDP. FTP is a good example of this because it
uses UDP for data, even tho it has to verify that every block is
copied.
Very true, if we're starting to go off topic.
Worse, IMHO, are developers who start with HTTP, which is
stateless, and then reimplement TCP/IP all over on top of it.
Duh, HTTP is built on TCP/IP.
To get back on topic, there is no such thing as a digital cable.
All cables, coax, unshielded, flat or round, etc. depend on voltages,
the voltages are always analog. The interpretation of the signal can be
set on the analog voltage crossing a specific voltage.
Cables can be rated for specific transmission speeds, but there ain't
such thing as a digital cable. Except, of course, among marketing folks.
