HTTP and The Web (Internet)

When you say, 'the Internet,' what comes to mind for most people is, in fact, the World Wide
Web. The World Wide Web, or just the Web, is not the Internet. Instead, it is a method of using
the Internet to exchange information between computers. The Web uses http or hypertext
transfer protocol and services known as web browsers and web servers to allow information in
the form of web pages to be exchanged between local and remote computers.
On the local side, what you see is the web browser. Information from the remote computer is
sent to your local computer using the http protocol. The web browser interprets that
information and displays it on your local computer in the form of web pages.
The hypertext part of the http protocol refers to a non-linear method of presenting
information. Text is normally read in a linear fashion: word 2 follows word 1; sentence 3 follows
sentence 2; paragraph 5 follows paragraph 4. The idea of hypertext allows information to be
viewed in a non-linear way. This is the major difference between hypertext and the older,
plain text methods of displaying information.
With hypertext, words and ideas can connect, not only with the words that directly surround
them, but also with other words, ideas or images. Hypertext is not restricted to the Web. Most
full-featured word processors will allow you to create locally stored pages in web or http
format. These pages are read using your web browser and act as would any other web page,
only they are stored on your local computer, not a remote computer
On your local Http and The Web Http and The Web computer, you use a client program called a web browser. Contrary to what
you might have been lead to believe, there are actually a number of web browsers available
for both Windows and Linux. These include Microsoft's Internet Explorer, Netscape Navigator,
and the Mozilla Firefox browsers.

You can also create your own web page. The easiest way to do this is to use one of the
common word processors, such as Open Office, Microsoft Word, or WordPerfect. These
programs will allow you to produce simple web pages, combining text, hypertext and images
Plenty of people have made useful, clever and innovative web pages using these simple
But these pages aren't flashy. Flashy means frames and scripts and animations. It also means
spending lots of money on a fancy web page design program. These programs allow you to
create many interesting effects on your web page, but they are more complex to use than
the word processors that you are probably already familiar with.
Once you have the pages designed, you'll need a computer to put them on, so that other
people can view them. This is called web hosting.
The hosting computer will be running a web server. It is possible to run one of these servers
from your own home, using your own computer, but there are several drawbacks, the primary
one of these being persistence. Information stored on a web server is only available when
that server is powered up, operating properly and has an open connection. So, if you want to
run a web server from your own bedroom, you have to leave your computer on all the time;
you have to make sure that the web server program is operating properly all the time (this
includes troubleshooting hardware problems, controlling viruses, worms and other attacks,
and dealing with the inevitable bugs and flaws within the program itself), and you have to
keep a connection to the Internet open. This is why most people pay someone else to do all

A web hosting company will store your web page on their computer. A perfect web hosting
company will have multiple, redundant servers and a regular backup policy, so that your
service is not lost because of hardware problems, a support staff to keep the server running
despite hacker attacks and program bugs, and a number of open connections to the
Internet, so that all your have to do is design your web page, upload it to the hosting
company's server, hang up the phone, turn off the computer, and go to sleep, and your web
page will be available to the entire world.
It's also possible to find organizations that offer free web hosting. Some of these organizations
are funded by paid advertising, which means that anyone who wants to view your web page
will first have to view someone else's advertisement. But they don't have to buy anything, and
you don't have to pay anything.
