Internet Explorer |
| |
Microsoft's free
Worldwide Web browser for Microsoft Windows, Windows 95, Windows

Navigator (which runs on many more platforms). Both support
the same core features and offer incompatible extensions. |

ISP - Internet
Service Provider |
| |
An organization
that provides its customers with dialup access to the internet
for a fee. Generally, ISPés only provide their users with an
internet connection, an electronic mail (E-mail) address, and
in some instances, World Wide Web Browsing software. You can
use a local ISP that has access numbers in your local calling
area, or you can use a national ISP that provides local-access
numbers across the country (e.g.. Earthlink, AT&T Worldnet,
America Online, CompuServe, etc.). |

JavaScript |
| |
(Formerly LiveScript)
Netscape's simple, cross-platform, Worldwide Web scripting language,
only very vaguely related to Java. JavaScript is intimately
tied to the Worldwide Web, and currently runs in only three
environments - as a server-side scripting language, as an embedded
language in server-parsed HTML,
and as an embedded language run in browsers.
JavaScript may end up being more popular and
entrenched than Java, due to the current (May 1997) prevalence
of its primary platform (see below), and its ease of learning.
It has a simplified C-like syntax. Its functionality is currently
limited, being aimed primarily at enhanced forms, simple web
database front-ends and navigation enhancements.
JavaScript originated from Netscape, and for
a time, only Netscape products supported it. Microsoft now
supports it, but as a "work-a-like" called JScript. The resulting
inconsistencies make it difficult to write JavaScript that
behaves the same in both Netscape
Navigator and Microsoft Internet
Explorer. This could be attributed to the slow progress
of JavaScript through the standards bodies.
JavaScript runs "100x" slower than C, as it
is purely interpreted (Java runs "10x" slower than C code).
Netscape and allies say JavaScript is an "open standard" in
an effort to keep Microsoft from monopolizing web software
as they have desktop software. Netscape and Sun have cooperated
to enable Java and JavaScript to exchange messages and data.
JavaScript should not be confused with Java,
and is a Netscape, not Sun trademark.

JPEG - Joint
Photographics Experts Group |
| |
(pronounced jay-peg).
A color image graphics
compression format in which a lossy compression method is used
and some data is sacrificed to achieve greater compression.
The compression format looks for large bodies of color in a
picture and throws away big chuncks of this redundant information
to »compressŔ the data and make it transfer faster on the net. |
