| ADSL: |
(Asymmetric Digital Subscriber Line). One type
of Digital Subscriber Line technology, a high-speed
transmission method that works over existing, twisted-pair
copper wires. In this method, downstream rates are
faster than upstream rates. Maximum speeds range
from 1.544 Mbps to 8 Mbps, but can depend on your
provider, line conditions and proximity to a telephone
switching station. |
| AIFF: |
(Audio Interchange File Format) A file format
that is used to store high-quality sampled audio
and musical instrument (MIDI) information. AIFF
files are similar to WAV files in both size and
quality. Though AIFF files were originally created
by Apple, audio programs on both the Mac and PC
can usually read them. |
| Algorithm: |
A complex mathematical procedure or formula which
seeks out repetitive data and replaces it with a
code. More advanced algorithms take into consideration
the limitations of human perception. The formula
which determines how to compress and decompress
data. |
| Amplifier: |
A network component, also known as a Repeater.
Amplifiers increases the power of a signal when
it is lost due to attenuation. They allow signals
to cover greater distances in a LAN environment. |
| Analog: |
Analog technology refers to electronic transmission
accomplished by adding signals of varying frequency
or amplitude to carrier waves of a given frequency
of alternating electromagnetic current. Broadcast
and phone transmission have conventionally used
analog technology. Standard audiotape and videotape
recordings are produced by an analog process, as
a continuous wave, rather than digitally in a binary
form. |
| Animated GIF:
|
A type of animation that uses multiple GIF picture
files in rapid succession to simulate movement.
Unlike Java, Dynamic HTML, or Shockwave, creating
animated GIFs does not require high-level programming
or design skills. Some examples of animated GIFs
are moving logos and bouncing balls on a Web site. |
| Animation: |
A series of still images displayed quickly to
simulate motion. Some key examples of Web animation
include Shockwave, Flash, and animated GIFs |
| Application
Layer: |
The seventh layer in the OSI (see OSI - Open System
Interconnection) model. The Application layer defines
program to program communication, or how applications
access network services. Services defined by the
Application layer include file transfer, job transfer
and terminal emulation. |
| Artifacting: |
The distortion that occurs when audio or video
is compressed to a very low bit rate. Sometimes
called noise. |
| ASF: |
Most streaming media files encoded for use on
the Windows Media platform have a .asf extension.
This is an actual audio/video file, as opposed to
an ASX file. |
| ASX: |
A metafile which points to a Windows Media audio/video
presentation. |
| ATM: |
(Asynchronous Transfer Mode) – A networking
protocol designed to move multimedia data around
with high reliability and speed. Some ISPs use ATM
as the protocol for their backbones. Unlike Ethernet,
which supports speeds of up to 100 Mbps, ATM allows
a bandwidth of 25 Mbps to 622 Mbps. |
| AVI: |
(Audio/ Video Interleaved) - A Microsoft-specified
format for saving audio and/or video clips, referred
to by Windows as "Video for Windows."
You can play the files through the Media Player
in Windows or through many popular browser plug-in
multimedia players. |
