ADSL
Abbreviation of Asymmetric Digital
Subscriber Line. ADSL is one kind
of broadband line. It relies on the
conventional copper wires of telephone
lines but supports transmission of large
amounts of data by using the high-
frequency bandwidth separate from
audio signals. The upstream rate of
communication (for data sent from
the user's terminal) is slower than the
downstream rate (sent from the provider to
the user's terminal), hence the description
"asymmetric". Transmission speeds vary
depending on the contracted service.
ATRAC AD
Abbreviation for ATRAC Audio Device.
A general term for devices that can play
audio data in the ATRAC format.
ATRAC
One of the "ATRAC" audio compression
technologies developed by Sony which
realizes high sound quality with
approximately 10 times the compression
rate of audio CDs.
ATRACplus
ATRAC3plus is an enhanced version
of ATRAC3. It realizes 20 times the
compression ratio of audio CDs, but with
no loss in sound quality.
Bit rate
The bit rate is a measure of data volume
expressed in bits per second (bps).
110
GB
Broadband
General name for communication lines
that use a broad frequency bandwidth
for sending and receiving large amounts
of video or audio data at high speed.
Currently, ADSL, CATV, FTTH and other
systems are identified as broadband.
Broadband router
For Internet connections through ADSL
or a cable TV line, devices called ADSL
modems or cable modems are used.
However, for Internet access from multiple
terminals connected at once, a broadband
router is used.
Byte
One of the fundamental units used to
express digitized data in computers.
Digitized data is commonly expressed in
binary digits (zeros and ones). A single
unit of data is one bit. One byte consists of
eight bits.
Condensation
Condensation occurs inside the unit
during where there is a quick rise in
temperature, as when a heater is turned
on. If condensation occurs, keep the unit
turned off until the moisture evaporates.
DHCP
Abbreviation of Dynamic Host
Configuration Protocol. A system for
automatically allocating configuration data
required for an Internet connection.
DLNA
Abbreviation of Digital Living Network
Alliance. The DLNA is a nonprofit
organization that establishes design
guidelines for digital content shared over
networks.
