Gateway
|
The technical meaning is a
hardware or software set-up that translates between
two dissimilar protocols, for example Prodigy has a
gateway that translates between its internal,
proprietary e-mail format and
Internet e-mail format. Another,
sloppier meaning of gateway is to describe any
mechanism for providing access to another system,
e.g. AOL might be called a gateway to the
Internet.

Gopher
|
A widely successful method of
making menus of material available over the
Internet. Gopher is a Client and
Server style program, which requires that
the user have a Gopher Client program.
Although Gopher spread rapidly across the globe in
only a couple of years, it has been largely
supplanted by Hypertext, also known as
WWW (World Wide Web). There are still
thousands of Gopher Servers on the
Internet and we can expect they will remain
for a while.

Hit
|
As used in reference to the
World Wide Web (WWW), “hit”
means a single request from a web
browser for a single item from a web
server; thus in order for a web
browser to display a page that contains 3
graphics, 4 “hits” would occur at
the server: 1 for the HTML page, and
one for each of the 3 graphics.
“hits” are
often used as a very rough measure of load on a
server, because each “hit”
can represent anything from a request for a tiny
document (or even a request for a missing document)
all the way to a request that requires some
significant extra processing (such as a complex
search request), the actual load on a machine from
1 hit is almost impossible to define.

Hit Counter
|
The hit counter
feature is a graphic that displays the number of
times that page has been accessed, many options
exist and most are free, some have very advanced
Web statistics, others only display a count
of "hits".

Home Page
(or Homepage)
|
Several meanings. Originally,
the web page that your browser is set
to use when it starts up. The more common meaning
refers to the main web page for a business,
organization, person or simply the main page out of
a collection of web pages, e.g. “Check
out so-and-so’s new Home
Page.”
Another sloppier use of the
term refers to practically any web page as a
“homepage”, e.g. “That web
site has 65 homepages and none of them
are interesting.”.
A better and more appropriate
use for "Home Page" is to call the default
page of a web site that way, and no
others.

HTML

HyperText Markup Language --
The coding language used to create Hypertext
documents for use on the World Wide Web
(WWW). HTML looks a lot like
old-fashioned typesetting code, where you surround
a block of text with codes that indicate how it
should appear. Additionally, in HTML you can
specify that a block of text, or a word, is linked
to another file on the Internet. HTML
files are meant to be viewed using a World Wide
Web Client Program, such as Netscape
or Mosaic.
