TUTORIAL
What is the Internet
During the past few years, the new technologies - -
particularly computers - - have appeared in almost every aspect of our
life.
With a computer, anybody may collect, archive, reconstruct, and share
information with each other. While being connected to the Internet ,we can read
the news, find
Information and even purchase goods and services. Computers
are becoming absolutely necessary at work and important for leisure. We can even
listen to music ,play games, or watch movies.
Moreover, with a computer at
home and Internet connection, we can easily communicate with other people - -
send postcards, and electronic letters that are delivered practically instantly,
even to locations on the other side of the planet.
You may wish to check out
the information about the place where you are planning to spend your vacations.
Having Internet connection means you can check offers from travel agencies,
order a flight, book n hotel or rent a car.
You will probably even be able
find photos of your hotel room and gather information on numerous interesting
places in the area, the best restaurants and other attractions.
The Internets
is a global network of computer networks.
Anyone may use the email and
look over the Internet pages with a
web browser because the computer is
connected to the Internet
and it communicates with other computers using so
called
Internet protocols.The Internet is a wide network of
computers which communicate with one another,using standard Internet
protocols. Computer software translates the information that your computer
received from a remote computers and therefore you can look up
the web pages,
and successfully send emails and check your mailbox.
While using web browser
, you enter a certain Internet location in the navigation bar In order to view a
certain site.
An Internet location, sometimes called URL , is a
location of a
particular computer that is connected to the Internet.
For
example, when you enter a location http;//www.websitewizard.com, you may expect
that the WebsiteWizard homepage will appear in your web browser. From your
computer’s on the other hand, when you entered a URL and requested an action
of
the web browser, the computer started looking for a server on which
WebsiteWizard is located. As it found the server, both computers entered into
dialog. Your computer
requests and receives a website data. The data is
transferred to your computer and displayed on your screen.
Almost ever
computer connected to the Net has a unique
address. There two systems
of addressing computers in the
Internet - - one is the system of domain
names and the other
one consists of the series of numbers ( so
called IP address , e.g.
207.8.198.8). The set of four numbers enables
any other computer
to find it. Domain Name Servers (DNS) translate
this number
into words.
An Internet domain name is an exclusive web
address that
Identifies and names a computer connected to the
Internet.
Domain Names are human friendly addresses of the computers
that
became connected to the Internet.
As the Internet user enters a
domain name, such as
www.yourdomainname.com
<http://www.yourdomainname.com> into the address box, the web
browser
transfers it into an IP address and connects to the website to
show
the page.
Please note that there might be more than one domain name
that
points to the IP address of your account.
Electronic mail systems
also use DNS. An email is nothing else than the address to an account on a
certain server. It not only identifies the server but also the user to whom a
message should be delivered.
When you send an email message to John Smith
whose email address isJohn.smith@yourdomainname.com
<mailto:John.smith@yourdomainname.com> , your computer will know that it
should deliver the
message to the computer related with that particular
domain name and that the message should appear in the mailbox of the user named
john . smith.
A server is a computer where the website is hosted and
made
midely accessible to the Internet network.
With your
WebsiteWizard account , you can create a new page ,and than it is Automatically
made accessible for the Internet users through the WebsiteWizard server.
If you register a domain name with WebsiteWizard it will point at your website,
and DNS will assign this domain name with the IP of your
website.
