WHAT IS THE INTERNET?
The Internet can be described as a:
“Huge collection of computers around the world”
We can say that these computers are:
“All linked together, and they can “talk” to each
other, sharing information and ideas”
If YOUR computer is connected to the
Internet, then it will be able to:
“Connect to millions of other computers around the
world”
HOW TO CONNECT TO THE INTERNET
To connect your computer to the Internet, you will need the
following:
COMPUTER
SYSTEM
TELEPHONE LINE
This will give you a computer that
can access the Internet:
A MODEM
INTERNET
SOFTWARE OR
BROWSER
WHAT CAN YOU DO ON THE INTERNET?
The Internet can be used in many different ways,
these include:





Sending electronic letters to people.
Read pages on the World Wide Web.
Play games with people on the other side of the
world.
Chat to people.
Buy things on the Internet and have them
delivered to your house!
WORLD WIDE WEB
What is the World Wide Web?
“It is part of the Internet and is made up of
millions and trillions of pages of information!”
When we look up the Internet, we call it:
WEB PAGES:
The pages are linked using a HYPERLINK.
This is usually shown with the word in blue
and underlined. If you move the mouse over
the word it will change to a HAND
Also pictures can be hyperlinks
as well, again the same thing happens
when you move your mouse over the
picture, the hand appears.
The use of the Internet has been in the news a lot
recently.
This is because if it’s not used properly and safely,
like with anything else, bad things can happen.
Remember there are all kinds of different people
using the Internet for different things. Some
people use the internet disguised as someone else, so
you always have to be careful.
Therefore there are certain rules that YOU
SHOULD USE WHEN “SURFING” THE
INTERNET.
DON’T:
Never give out your full name, address, phone
number, school name and address or any other
personal information. YOU NEVER KNOW WHOM
YOU REALY ARE TALKING TO.
Do not enter any competitions without asking your
parents first.
If you receive information that is abusive or makes
you uncomfortable, let your parents or teacher know.
Never respond to it yourself.
DON’T:
NEVER AGREE TO MEET SOMEONE YOU HAVE
“MET” ON THE INTERNET - you wouldn’t go into a
strangers car, so why meet someone you haven’t met or
know?
Do not click on any links that are contained in e-mail
from anyone you don't know. Such links could lead to
inappropriate web sites or viruses.
NEVER SEND YOUR PICTURE OR FRIENDS
PICTURE TO ANYONE YOU DON’T KNOW.
Do not give out your passwords to anyone (even best
friends), other than your parents.
DO’S
Follow the rules you and your parents have
set up regarding your use of the Internet.
Treat others on the Internet the way you want
to be treated! They are people, not computers!
Know exactly what your are “looking for”, and
use the standard search engines to start you
off (especially if you don’t know the web
addresses. Make sure you key in the web
address exactly.
IT IS COMMON SENSE!
FOLLOW THESE RULES, AND YOU
WILL HAVE A GREAT TIME
SURFING THE INTERNET AND
EXPANDING YOUR KNOWLEDEGE
OF THE WORLD.
HAVE FUN, SURFING!!
USING THE INTERNET:
The Internet has different things within it that you can do.
We are going to look at some of them. They include:
•Web Sites
•Chat Rooms
•E-mail
When using any of the above areas of the Internet, there is a
universal code that all users should use when using the
Internet.
These rules are about the way you BEHAVE ON THE
INTERNET AND THE WAY YOU CONDUCT YOURSELF ON
THE INTERNET. This is known as NETIQUETTE.
Again its common sense, think of it
this way, when you talk to your
friends, family or strangers you are
polite, sincere, behave well and say
things that mean something.
Therefore the way you behave
towards people face to face, you
should behave the same way while
you are on the Internet.
BEHAVIOUR ON THE INTERNET:
Be polite and courteous at all times. Remember that
you're not communicating with a computer screen, but
with a human being who has thoughts and feelings just
like you. So, always think of the person on the
receiving end of your messages.
Do not TYPE ALL IN CAPITAL LETTERS for
emphasis. IT LOOKS LIKE YOU ARE SHOUTING. If
you need to emphasize a word, use asterisks, like
*this* or lines, like _this_.
Be careful not to use rude or bad language online.
BEHAVIOUR ON THE INTERNET:
Don't break any laws. When you're on the net, follow
the same rules of behaviour that you would in real life.
Remember, if it is against the law in the real world, it
is against the law in the Internet or cyberspace.
Be brief whenever possible. Be patient with
newcomers.
Now answer the questions in TASK 2
which is in your work sheet.
ACCESSING THE INTERNET:
When using the Internet, there are different ways in
which you can access the Internet. These can be by:
1. Keying the web address.
2. Using a search engine.
1. WEB ADDRESS:
A web address is a quick and easy way to find information
that you want on a certain thing. Examples of web
addresses are:
www.bbc.co.uk
www.msn.co.uk
www.netsmartz.org
When you type in the web address, it will take you
to the organisations home page.
The home page is the “starting point” for most
organisations or people with web pages. It will tell
you what is in the site, what links there are, free
downloads etc.
NOTE:
THE ADDRESSES SHOULD BE TYPED
EXACTLY, OR YOU WILL END UP ON
A DIFFERENT WEB SITE.
2.
SEARCH ENGINES:
Perform searches for information on the Internet based on
the words or phrases you supply. Most popular search
engines are:
www.yahoo.co.uk
www.yahoo.co.uk
www.google.co.uk
The uk tells us it is a British site.
If you see com at the end of a
web site, then that is world wide.
When using search engines, you should always try and be
precise with your description of words. For example words like
“and”, “or”, “a” etc are very common, so the search engines will
ignore these words and concentrate on the other words.
For example. let’s say we wanted to look up information about
panama hats. We would go to a search engine, like Google, and
type in; “how to buy panama hats”. When the search was done it
would list all the sites relating to panama hats, but ignore common
words like “how to”. Like the result below.
Ignored common
words!
4. WEB PAGE:
This is a typical web page. We are going to study the
toolbar of the web page, so that we know what the
different icons do.
Here is the BBC’s home page.
We are going
to look at the
toolbar, so we
know how to
use it.
THE TOOLBAR
This is the menu bar, where you can save, print, keep your
favourites web sites etc.
FORWARD
BACK
These two buttons allow you to navigate
between the pages.
The back button allows you to back
though the pages, while the forward
button allows you to go the next page.
REFRESH
STOP
The stop button allows you stop
whatever you were doing, for
example downloading or moving to
another page. The refresh button
will allow you try and re-load the
web page, if you had any
difficulties.
This bar, allows you to type in your web address.
This button will take you to a web page which
allows you to search for things on the Internet.
When you click on the Favourites button, you will
see a list of your favourite web sites. You can
then click on one of the names to visit that site.
Clicking on the HISTORY button shows list of the
web pages which you have visited during the last
few days / weeks. This makes it easier to return
to sites, which you have looked at recently.
