To navigate the WWW, you also need a piece of software called a web browser. This is a program that knows how to look for files on the WWW and how to interpret them (display them on your monitor) once it retrieves them for you.

What on earth does all of that mean? Well, with a little practice, you will be able to decipher these cryptic lines too.
The first part (http
in the example above) is some technical
stuff that tells the browser what protocol to use in accessing and
downloading the file you have requested. The most common is http
(hypertext transfer protocol) but other prefixes that you may encounter are
ftp
(file transfer protocol) and gopher
(another
file transfer protocol). You really don't have to worry about this part but
be aware that every WWW document begins with one of these prefixes followed
by ://
The next section is the domain name. This
may tell you (more or less) where the files are located geographically.
In the example above (www.obliquity.com
), the domain name is
obliquity
and it is a commercial site (com
).
The www
part often precedes the rest of the domain name but
not always.
Domain names are fun to try to decode! Countries besides the United States
have domain names that end in two-letter abbreviations. Some are obvious
(uk
for the United Kingdom, ca
for Canada,
jp
for Japan) and some are not so obvious (de
for
Germany, ch
for Switzerland). Academic sites in the United
Kingdom always have ac
in the domain name whilst German
universities usually have uni-
followed by the name of the
university. Every country has its own setup.
In the United States, the us
abbreviation is rarely used. Some
common abbreviations that do appear in American domain names are
com
(commercial), edu
(educational),
mil
(military), net
(network), and
org
(organisation), among others.
The transfer protocol alerts the browser as to how to handle the files and
the domain name tells the browser on which computer the required file is
located. The remainder of the URL is a combination of subdirectory and file
names. The Meet the Family! home page is in
a subdirectory called family
and the actual name of the file is
index.html
. Most documents that are readable on the WWW have
file names ending in the suffix .html
or .htm
although there are other possibilities. The suffix tells the browser what
kind of file it is. A .html
file is a text file written in a
text formatting language called
HyperText Markup Language.
(See a simple tutorial at

if you want to learn more about it.) Images are usually .gif
or .jpeg
or .jpg
files.

You can certainly use these search engines to look for genealogy resources but some busy beavers have already done that for you and are maintaining assorted lists of WWW sites relating to genealogy. The most comprehensive collection of genealogy listings (and a good place to start exploring) is the fabulous Cyndi's List of Genealogy Sites on the Internet at the URL
Another trick to speed up download times is to turn off the image-loading option on your browser. Images take a long time load and a lot of people, including those who really should know better, have gone overboard with fancy graphics.
Also, be careful when you type in a URL. It is very easy to misspell a word or put a period where you want a slash. It is very frustrating to send for a document, wait several minutes, and then get an error message from the browser complaining that it can't find the requested document, all because you forgot a period or omitted a subdirectory.
However, nothing is permanent in cyberspace and the file that you have requested may no longer exist. If you get a "Code 404 : File Not Found" error but you are sure that you typed the URL correctly, try "backing up the URL." That is, eliminate the last part of the URL (either a file name or subdirectory) and try again. For example, if you try the URL
http://www.obliquity.com/family/contact.html
you will get a "code 404" error because that file does not exist
in that place. However, if you eliminate the file name
contact.html
and then try
http://www.obliquity.com/family/
you will have success! However, if you had gotten another error message, you could have tried
http://www.obliquity.com/
before running out of things to eliminate. At this point you have reached the domain name and cannot eliminate anything more.
