Advanced Encryption Standard
The successor of the now insecure DES. AES provides
strong and modern encryption, with long keys up to
256 Bit (DES used 56 Bit).

APIPA:
Automatic Private IP-Addressing
A scheme to self-assign an IP-Address to a
network device. The device selects an address of the
LINKLOCAL range 169.254.0.1 to 169.254.255.254 by
random. If this address is unused, it assigns it to itself.
Otherwise the next address is tested. It became
widespread with Windows 98.

ART:
Automatic Receive Transmit control
Special control for RS485 modes. In RS485 the
line driver for transmitting must be disabled (tri-stated)
when the device does not send data. In a 2 wire
configuration this is known as data direction change,
with 4 wire it is called line contention.
