ICANN. Internet Corporation for Assigned Names and Numbers. See InterNIC.
Icon. A graphic, usually small, which provides a link on a
webpage. It is easier to find than a text link.
Image map. Click on a different part of the picture, and it
will link to different pages. That's because that portion of the
image has been "mapped" to go to that other location.
IMAP. Internet message access protocol. The rules
followed by email programs. Differing from POP, IMAP can massage
information that is stored on the server, without having to
download it.
Internet. Two or more connected networks. The Internet is
the largest Wide Area Network of computers on the planet.
InterNIC. Integrated Network Information
Center. See also domain name and
domain name server.
Intranet. A company-internal network. The Internet is an
extranet because it is not held captive within the organization.
IP. Internet protocol. A set of Internet
standards. Your IP address is essentially your DNS number.
Every computer on the Internet is identified by a unique IP number.
IPP. See ISP.
IRC. Internet relay chat. A live network to share
messages back and forth dynamically, in a conversation.
ISDN. Integrated services digital network. Whereas DSL
connects point-to-point, ISDN may connect to many points, one at a
time. ISDN speeds are in the range of 128 Kbps. ISDN supports
voice, data and video.
ISO. International Standards Organization. This group sets
standards, in our case, for computers, which are used around the
world.
ISP. Internet service provider. This
company offers you a usually local telephone number as your point
of presence (POP) so that you may connect to the network. They also
offer connection software. Common services include email as
well as Web browsing. In common parlance, "ISP" is also
used to describe the company which hosts your website, because
ISPs often do that. A company which hosts a site but does not offer
the POP service is more properly called an Internet Presence
Provider (IPP).
Java. Designed for networks by Sun
Microsystems, this is a cross-platform (works the same way on
different computers) programming language. For it to operate on
your computer, the commands ("classes") must first
be downloaded. Java applets are designed so as to prevent putting
viruses or worms onto your system.
JavaScript. Designed specifically for use in webpages, the
JavaScript language differs from Java primarily in that it runs
"on the fly." This means that the browser interprets the
script line by line, as it is received, so it gets to work faster.
JPEG. JPG. Joint Photographic Experts Group. A
Web-oriented graphics format. A .jpg image is usually better
for color photographs than a .gif image.
Leased line. This is a wire or fiber optic cable which
connects your computer to the phone company or other discrete
point. Available around the clock, it provides the highest speed
data connection, usually at the highest cost.
Link. A hypertext connection. Also see Anchor. A link
may be absolute with the entire address such as
<a href="http://www.neguide.com">
Baughan's Northeast Guide</a>
between one site and another or
<a href="http://www.
rocksolidsite.com">Home Page</a>
within the same site. Or, it may
be a relative link such as
<a href="../index.htm">Home</a>
within the same site. An external link is between pages, and an
internal link is a bookmark (example at anchor)
within the same page.
Link farm. This is not a place
where you want to be. In theory, you would submit your site to
these places solely to increase your "popularity" (the
links coming in to your site). Actually, if you are there then you
can expect the reverse to happen. Search engines will likely
penalize you -- maybe even ban your site -- as they consider
this tactic to be spamming. So, how do you identify such
places?
- Is there descriptive text around the link, or just a series of
links? If there is no meaningful text content, it may well be
just a farm.
- Do they promote themselves as an FFA site (see free for all)? Offering a free listing is not the same as
being an FFA... it's a "flavor" which becomes
immediately evident.
- Are there dozens and dozens -- or maybe even hundreds
-- of links on the same page? The number of links is
arbitrary, but we think of anything over three dozen links on a
page as being too excessive -- a well structured site would be
better organized.
- Speaking of organization, is there any? Is everything
just lumped together, or are there clear categories of links?
(In a good site, restaurants would be grouped with other
restaurants, etc.)
Do they require
that you place a reciprocal link on
your own site? (Encourage is not the same thing as
require.)
- Look at the page's source code. Are there many links in there
which are hidden to the casual viewer? (If so, run away
real quick-like!)
Linux. This is a free operating system which is similar to and
highly compatible with the Unix system. Being open-source, you can
examine and alter the inner workings.
Log in. The process of entering your user name and password
to connect to an otherwise secure area of the Internet.
Megabyte. 1,024 kilobytes. It is the same as 1 bit
x2x2x2x2x2x2x2x2 = 8 bits to count numerically 0 to 255 =
1 byte, then x2x2x2x2x2x2x2x2x2x2 = 1,024 bytes = 1 kilobyte,
then x2x2x2x2x2x2x2x2x2x2 = 1,048,576 bytes = 1,024
kilobytes = 1 Megabyte.
Now, why is a Megabyte 1,024,000 instead of 1,000,000? 'Cause a
Kilobyte is 1,024 instead of 1,000, that's why. The strange number
comes from the computers base-2 orientation instead of base-10.
That's 'cause a bit is a digital switch on "1" or off
"0." The first bit is 1 or 0. The second bit is 1 or 0.
They are additive. So, in just two bits you can count to 4
elements, 0-3 -- 00=0, 01=1, 10=2, 11=3. In one byte, 8
bits, you can count from 0-255. So, "base ten" is
a purely human creation, to go along with our (hopefully) ten
fingers and ten toes. It has nothing to do with the real
world. If it weren't for cavemen inventing shoes, we'd
probably be on base 20.
Think about it. In 1793, the "meter" was defined to be
1 / 10,000,000 of the distance from the pole to the equator. In
1906 it was defined to be 1,000,000 / 0.64384696 wavelengths
in air of the red line of the cadmium spectrum. In 1960 it was
changed to 1,650,763.73
wavelengths in vacuum of the radiation corresponding to the
transition between levels 2p10 and 5d5 of the krypton 86 atom.
In 1983 they made it the length traveled by light in vacuum during
1/299,792,458 of a second.
Luckily, Nature couldn't care less about our inventions. Base 2.
On or off. That's it. That's Her way. And that's why it's
1,024.
Meta tag. Information stored in the header of a webpage
(normally invisible to the visitor). It contains information and
instructions to the browser about the page itself.
MIDI. Musical instrument digital interface. A format for
music files.
MIME. Multipurpose Internet mail extension. This is a
protocol which allows you to attach graphics, videos, music and
word processing documents to email messages.
Mirror site. This is a website which contains the same
information that is located on another site. If the site
abc.com is the same as def.com, then it may be
disqualified from listing by search engines.
Mnemonic. A created word or words which
allows you to remember. See also domain name.
Modem. Modulator/demodulator. This piece of hardware
connects your computer to the telephone line.
Mosaic. NCSA Mosaic (tm). Archaic. This is the first
browser that was implemented on Windows, Macintosh and Unix. It
came out in 1993, from the National Center for Supercomputing
Applications (NCSA), University of Illinois in Urbana-Champaign.
MPEG. Moving Pictures Expert Group. A format for video and
music.
Multimedia. The ability to combine sound with pictures and
text.
Nest. To have one item within another. The figure is
nested in the small table which is nested within the larger table
on the page.
Network. Two or more computers connected together through a network hub, switch, or router.
NOC. Network operations center. The group that
controls the daily operation of the network.
Node. A single computer connection on a network.
Octal. A method of encoding a character in 3 bits, 000 to
111, representing 0 to 7. If your office computer is in such a
Base8 configuration, it might be about time to notify the boss that
Elvis has left the building.
Open source. Program software of which the code is made
available so that implementers may alter it to meet user
requirements.
