ADSL
|
Asymmetric Digital Subscriber
Line -- A method for moving data over regular phone
lines. An ADSL circuit is much faster than a
regular phone connection, and the wires coming into
the subscriber ’s premises are the same
(copper) wires used for regular phone service. An
ADSL circuit must be configured to connect
two specific locations, similar to a leased
line.
A commonly discussed
configuration of ADSL would allow a
subscriber to receive data (download) at
speeds of up to 1.544 megabits (not
megabytes) per second, and to send
(upload) data at speeds of 128
kilobits per second. Thus the
“Asymmetric” part of the acronym.
Another commonly discussed
configuration would be symmetrical: 384
Kilobits per second in both directions. In
theory ADSL allows download speeds of
up to 9 megabits per second and
upload speeds of up to 640 kilobits
per second.
ADSL is often
discussed as an alternative to ISDN,
allowing higher speeds in cases where the
connection is always to the same place.

Applet
|
A small Java program
that can be embedded in an HTML page.
Applets differ from full-fledged Java
applications in that they are not allowed to
access certain resources on the local computer,
such as files and serial devices (modems,
printers, etc.), and are prohibited from
communicating with most other computers across a
network. The current rule is that an applet
can only make an Internet connection to the
computer from which the applet was sent.

Archive
|
Usually a single file
containing many other files and directories, most
archives are compressed, one of the most common
types of compressed archives is the ZIP
which is mostly found on BBSes to pass
software around, examples of other archive type
are:
HQX, TAR, BIN, SEA, SIT,
RAR, LHA, Z, GZ, GZIP, SQX, LHZ....
And many more...

Archiver
|
The program used to make
"archives", which consists of many files and
directories all packed together within one single
file, called "archive", usually these
archives are compressed to take less storage space
and reduce the transfer times when
downloading or uploading them, some
archives aren't compressed, e.g.: the
UNIX TAR archives.

ARPANet

Advanced Research Projects
Agency Network -- The precursor to the Internet.
Developed in the late 60’s and early
70’s by the US Department of Defense as an
experiment in wide-area-networking (WAN )
that would survive a nuclear war.

ASCII
|
American Standard Code for
Information Interchange -- This is the de facto
world-wide standard for the code numbers used by
computers to represent all the upper and lower-case
Latin letters, numbers, punctuation, etc. There are
128 standard ASCII codes each of which can
be represented by a 7 digit binary number: 0000000
through 1111111.

Auto Responder
|
The auto responder feature
allows you to automatically send a text
file/message reply when you receive an
e-mail.
This is useful if you want to
let people know that you are on vacation and will
not be able to immediately reply to their
e-mail or simply to let them know that their
mail has been received and they will get a follow
up later.
