A set of protocols used to
exchange information between
external programs and an

programs are normally
written in Perl or C. |

Client / Server |
|
Computer technology that
separates computers and
their users into two
categories. When you want
information from a computer
on the Internet, you are a
client. The computer that
delivers the information is
the server. A server both
stores information and makes
it available to any
authorized client who
requests the information.

Co-location |
|
Co-location is when an
individual places a computer
that they own on the
backbone of the internet
owned by someone else.
Examples of this are
companies that want to use
their own web server but do
not yet have either the
finances or the expertise to
set up their own dedicated
line. |

| Compression |

order to save space and reduce transfer
times. Typical file extensions for
compressed files include .zip (DOS/Windows)
and .tar (UNIX). |

Cookie |
|
A piece
of information (login
names, passwords, online
"shopping cart" items,
user preferences, etc.)
sent by a web server to
a web browser and saved
to the computer. These
"cookies" can then be
used at a later date to
restore the information
when the web server is
accessed again. Cookies
are usually set to
expire after a
predetermined amount of
time. |
