Alternating current
(gcide) | Alternating current \Al"ter*nat`ing cur"rent\ (Elec.)
A current which periodically changes or reverses its
direction of flow, especially an electric current that
reverses direction sinusoidally, as is used for most domestic
and industrial power requirements. Contrasted with {direct
curent}.
Syn: AC
[Webster 1913 Suppl. +PJC]
Note: The common household current is alternating.
Alternating current is easier than direct current to
transform to high voltage and back, making
long-distance transmission more efficient.
[PJC]electric current \electric current\, electrical current
\electrical current\,
the movement of electrically charged particles, atoms, or
ions, through solids, liquids, gases, or free space; the term
is usually used of relatively smooth movements of electric
charge through conductors, whether constant or variable.
Sudden movements of charge are usually referred to by other
terms, such as spark or lightning or discharge. In
metallic conductors the electric current is usually due to
movement of electrons through the metal. The current is
measured as the rate of movement of charge per unit time, and
is counted in units of amperes. As a formal definition, the
direction of movement of electric current is considered as
the same as the direction of movement of positive charge, or
in a direction opposite to the movement of negative charge.
Electric current may move constantly in a single direction,
called direct current (abbreviated DC), or may move
alternately in one direction and then the opposite direction,
called alternating current (abbreviated AC).

alternating bit protocol
(foldoc) | Alternating bit protocol
(ABP) A simple data link layer protocol that
retransmits lost or corrupted messages.
Messages are sent from transmitter A to receiver B. Assume
that the channel from A to B is initialised and that there are
no messages in transit. Each message contains a data part, a
checksum, and a one-bit sequence number, i.e. a value that
is 0 or 1.
When A sends a message, it sends it continuously, with the
same sequence number, until it receives an acknowledgment
(ACK) from B that contains the same sequence number. When
that happens, A complements (flips) the sequence number and
starts transmitting the next message.
When B receives a message from A, it checks the checksum. If
the message is not corrupted B sends back an ACK with the same
sequence number. If it is the first message with that
sequence number then it is sent for processing. Subsequent
messages with the same sequence bit are simply acknowledged.
If the message is corrupted B sends back an negative/error
acknowledgment (NAK). This is optional, as A will continue
transmitting until it receives the correct ACK.
A treats corrupted ACK messages, and NAK messages in the same
way. The simplest behaviour is to ignore them all and
continue transmitting.

phase alternating line
(foldoc) | phase alternating line
(PAL) The video signal format used in the UK
[where else?].
PAL uses Amplitude Modulation for the video information, and
Frequency Modulation for the audio information. The phase
of the colour subcarrier is reversed on alternate lines
which (together with the use of a delay line) allows the
receiver to cancel any phase errors introduced in the path
between the studio and the end-user's receiver. Such phase
errors are quite common and would cause the displayed colours
to shift in hue.
The US equivalent, NTSC, does not have this feature and thus
requires a user control to correct for transmission phase
errors, hence the mis-expansion "Never Twice the Same Colour".
