Protocol service using IP. It adds the ability to distinguish among

multiple destinations within a

given host.

UTP See Unshielded Twisted Pair.

XMODEM Protocol XMODEM is a serial communications protocol used to

transfer ASCII or binary data. XMODEM uses 8-bit

characters and transfers data using 128-byte blocks, each

of which is followed by a checksum or CRC. If the

checksum (CRC) on a block is correct, the next block is

sent; otherwise the same block is retransmitted.
