2a) The Web was firstly conceived by Paul Baran in 1962, within 11 volumes. Basically, Baran meant to solve the problems risked within a centralised communication system: the central seed's destruction would indeed impede communication. Baran thus designed a network as a web, in which data could travel dynamically, by patiently and methodically seeking the shortest available path.
2.Web ~NEXT to 2b

2b) However, it took seven years for Baran's 1962 idea to start taking shape, and finally, in1969, four computers of four American Universities were linked by the fisrt threads of the ARPANET. As shows the gr@ph on the right, 10 years later, by September 1972, thousands of kilometres of communication copper cables criss-crossed America and linked 23 computers; the first em@il ever was sent: it said "WYSIWYG", meaning: "what you see is what you get". Yet another five years later, in 1977, there were only 111 computers connected to the Arpanet. By 1980, the Arpanet, as shows the graph below, was getting even more complex and was connected to Hawaii and even London, where the communication network was then called Janet, and later: SuperJanet

3) Here are  8 blue Web servers.
Their probable width :  ± 40 cm ;  ± 15 inches. 
The probable data stockage capacity of each server : 
± 16-20 GB.

Web Servers host dom@ins and /or Web sp@ces.
Web Servers are not always accessible through the Web, or Internet, since they may also be integrated within private Intranets; in 1991, there was just ONE Web server !

In 1992, there were only 26 functional Web servers, but 1500, in 1994... Nowadays, there are Web servers all around the planet: 42,000,000!
How many 15MB Web sp@ces could be contained in one of the above Web servers?

4a) Visible N@vigators, browsers, and invisible "N@vigators": DNS Servers
To re@ch a dom@in, a sp@ce, or a p@ge, situated in a Web server,
you tr@vel through the user friendly  interface of a "visible n@vigator", or browser,
generaly with Internet Explorer, 95%, or Netscape Navigator (and Communicator), 4%.

Furthermore, to tr@vel on the Internet of copper, glass, and plastic,
that now covers the whole planet, you n@vigate, amongst other hardware,
 through Bridges and Routers and DNS servers that are invisible to you.

DNS servers choose the fastest available road
between your computer and the dom@in that you wish to @ccess,
with the help of the DNS protocol, or  Domain Name System.

DNS servers form a network of their own and  know all domain names,
DNS servers automatically translate a dom@in n@me  into its IP, a sequence of 4 numbers,
each of which is between 0 and 245...To whom belongs IP 17.112.152.32?

4. "N@vigators": DNS Servers ~NEXT to 4b

.
4.b) DNS servers choose their traject according to available ro@ds :
from Quebec, you re@ch the Web servers that host the dom@ins of GeoCities.com, in California,
by tr@velling through ±15 DNS servers.
You may see traces of that ro@d, by doing a TRACERT:
Under Windows, click Start, Programs, Commands, MS-DOS, then, in MS-DOS, write :
tracert: www.google.com
How many DNS servers to get there ?

Verify three @dresses of three dom@ins, one of which, in Quebec.
How many  DNS servers to tr@vel there?
What are the IP #s of those three dom@ins?

5a) Dissection of a dom@in's URL @ddress, as http://www.google.com

-http, hyper text transfer protocol, is one of the protocoles TCP/IP that computers speak together.

-www means World Wide Web (that is the cyber sp@ce where @re all dom@ins).

When you tr@vel on the Web, neither http, nor www are compulsory, to re@ch a dom@in:

Just writing google.com will get you there, because, by default,
you use http to tr@vel onto the World Wide Web.
http://google.com will also get you there,
just as www.google.com.

Disgression: Did you know the www2.google.com and the www3.google.com?

5. Dom@ins ~NEXT to 5b
.
5b) Dissection of dom@in n@mes:
-google is the second level domain (SLD)
-com represents the extension,and is also called top level domain (TLD).
There are generic extensions with three letters or more, as     .com    .net    .org    .info
and geographical extensions with two letters, as .ca    .ch    .mx

So, the SLD and TLD  google.com is a dom@in n@me;
that name is unique, and may only be used by one holder at the time, as djo.ca
A dom@in n@me may be written in capital letters or not: it is not case sensitive.

Indicate the URL @ddress of four p@ges or Sp@ces that you often visit.
Identify which part of the @ddress is the dom@in n@me.
Find out to whom belongs those dom@ins, with a research WHOIS.

6.)Within ,,,Sp@ce, is the name given to what is often called a Web site, Website or Web space. A Web sp@ce, or sp@ce, may be a reserved dom@in, or be contained in a dom@in. Djo.ca is a dom@in, and also a sp@ce; djo.ca cont@ins the Web p@ges that form . The dom@in sp@ce djo.ca is limited to 25 MB, and is hosted in a Web Server whose owners are specialised in hosting sp@ces and /or dom@ins. Such a short address sure is easy to remember!

I also have a personal Web sp@ce, joseph.deneault, limited to 5 MB. That sp@ce is hosted for free in the Web servers of my (ISP) Internet Service Provider Sympatico.ca.  Since my main @ddress is http://www3.sympatico.ca/joseph.deneault/, when I add a file into my sp@ce, it appears after my @ddress: www3.sympatico.ca/joseph.deneault/zdjeault.html

My other personal sp@ce, called djeault, is limited to 15 MB, that free sp@ce is hosted in the Web servers of the subdom@in geocities.com, @t: http://www.geocities.com/djeault/

Does your Internet Service Provider offer you free sp@ce? How much?

7.) Within the  PROJECT, as hornets who build nests up to 9 honeycombs high, and the Sun who spat 9 planets, you will build an @malgam of 9 Web p@ges, in your personal Web sp@ce, which may be hosted, in the Web servers of the reserved Web dom@in, geocities.com, owned by Yahoo!

If so, your Web sp@ce's @ddress will be http://www.geocities.com/TheNameYouWillChoose
If you choose mary, and upload the file banana.html, you'll thereafter find it at
http://www.geocities.com/mary/banana.html

Having your own Web sp@ce with Yahoo! doesn't impede you from investing in a domain n@me with an authorized register and /or from opening another Web sp@ce hosted within a specialised Web Server, or else through your ISP, Internet Service Provider's servers. Nevertheless, publishing your p@ges in redundance in a personal sp@ce within geocities.com is a logical security; furthermore, the PageBuilder is a free, friendly user program that offers capacities neither possible within Composer 4.8, nor 7.1.
.
Module 000 will take you through your request of 15MB of free Web Sp@ce in Yahoo!'s Web servers
and will also show you how you may register into the .
For both registrations, we'll give a glimpse to SECURITY on the Web.

What User n@me will you choose? Keep it short, simple, but meaningful!
It has to take the somewhat Native Form:
GreenHorse
RoaringDragon
HappyMonkey
PatientRooster
thus,
One of the 12 Chinese Animals, preceded
by either a color, an ungoing action, a feeling, or a quality.
