THE INTERNET AND THE WORLD WIDE WEB
PART 2
The Internet
All over the world there are computers that can connect with each
other. The connections are made through different technologies,
but most often through phone lines. This network of computers is
called the Internet.
The Internet is the term for all the hardware in this worldwide
network – computers, cabling, phone links, radio masts and
satellites. The purpose of the Internet is to carry information
quickly and cheaply and directly into businesses and into homes.
Your computer has to have the correct software for connecting to
the Internet. This software is called an Internet browser. Here
are the icons of the most popular browsers.
Internet Explorer
So now you know that the computer that you use to connect to the
Internet will have:
 A browser installed in it
 A connection into a telephone system.
The World Wide Web (WWW)
There are a number of services on the Internet, which help to organise
the sharing of information. You may have heard about some of these,
such as electronic mail, user groups and chat rooms. The World Wide
Web is one of these information services on the Internet.

THE INTERNET AND THE WORLD WIDE WEB
The WWW provides information in the form of text, pictures,
graphics, sound, animation and video. That means it uses
multimedia.
The WWW is used by:
 art galleries to tell people about their collections of paintings
 shops to advertise and sell their goods
 education to make learning more fun
 cinemas and clubs to advertise their programmes
 travel agencies to sell holidays and flights
 and many, many other organisations.
Organisations like those above that want to provide information
create a WWW website.
A website is a collection of web pages with information on the
organisation and what it has to offer. People who want
information on an organisation connect to the Internet and visit its
website.
The first page of a website is called the home page. This is often
the starting point of a visit to a website because the home page
has links to other pages in the website.
Home

Page 1
Page 3
Page 4

Page 6
Page 7
The home page has a web address so that people can find it.
You often find the web address of an organisation’s home page at
the bottom of its adverts.
There is an online animation available called ‘Websites’

SEARCHING THE WORLD WIDE WEB
PART 3
Searching for information
You often search for and find information without realising how
you do it.
You really answer two questions in searching for information:
1.
2.
What am I looking for?
Where should I look?
Here are some examples:
What am I looking for?
What’s on TV on Tuesday
night?
The phone number of Joe
Smith, Ayr
Train times from Glasgow
to Ayr
Where should I look?
TV magazine on the Tuesday page or
Tuesday’s newspaper and after 6pm.
Phone book of the Ayr area under
‘Smith’
Train timetable for the Glasgow to
Ayr route
Your choice of words in the column What am I looking for? is
very important. They tell you exactly where to look for the
information. The clearer you are about what you are looking for,
the quicker and easier it is for you to find it.
The words you choose are called the key words for your search.
Here are the key words for the searches above:
What am I looking for?
What’s on TV on Tuesday night?
The phone number of Joe Smith,
Ayr
Train times from Glasgow to Ayr
Key words
TV, Tuesday, night
Phone number, Joe Smith,
Ayr
Train, Glasgow, Ayr
Your skill in choosing good key words is important for searching
for information on the WWW.

SEARCHING THE WORLD WIDE WEB
Searching for information on the WWW
How do you find the information you want when there are millions
of WWW websites? How do you find the correct website? Could
there be more than one website with the kind of information you
want?
The answer to all these questions is that a special kind of program
searches the WWW for you. This program is called a search
engine.
A search engine looks through all the WWW websites and gathers
details of those that have the kind of information you want. It sends
these details back to your computer. You can then look through
these details and decide which websites you want to visit.
Now it is time to start searching the WWW for specific information.
Imagine that you are going wind surfing off the west coast of
Scotland. You need information on what the Met Office is saying
about tomorrow’s weather.
You must follow carefully the steps set out for you. The first step
is to connect or log on to the Internet.
Step 1: Logging on to the Internet
 Start up your computer.
 Look for one of these two icons on the desktop.
Internet Explorer
 Click whichever icon you find to start up the browser.
Remember the browser connects your computer to the Internet.
The first WWW page you see may take a while to appear,
especially if it has lots of graphics.
It may be the home page of your own school or college, or the
home page of a computer company, or a blank page.

SEARCHING THE WORLD WIDE WEB
Step 2: Starting up the search engine
There are many search engines. Some popular ones are Google,
Yahoo, Lycos and Altavista.
You are going to learn how to use Google.
Start by entering the address of Google’s home page.
Here is the address: www.google.com
(you can also use the UK home page www.google.co.uk)
You enter it in the address bar near the top of the WWW page on
your screen.
Just now, the address bar might hold the address of your
organisation’s home page. If so, you have to change that.
 Click in the address bar.
The address there becomes highlighted in blue.
 Enter www.google.com and press Return.
The Google home page will open on your screen.

Step 3: Entering the key words for the information search
Enter Met Office
UK here.
Click Google
Search when
finished.
The Google program eventually sends back to your screen details
of pages which mention ‘Met Office’. A WWW page similar to this
will open.
Pages found
by Google
mentioning
‘Met Office’.

SEARCHING THE WORLD WIDE WEB
Step 4: Moving to the correct page using a link
 Move the pointer slowly down the list of pages on the left.
Notice that it changes at times into a hand with a pointing finger.
For example, it happens over the underlined text in blue.
When this happens, the pointer is over a link to another page.
 Click on the link Met Office Homepage (see previous screenshot).
A page like this will appear:
This page shows the weather forecast. You may need to use the
scroll bar to see the whole page.
You have successfully searched the WWW to find what
tomorrow’s and the next day’s weather will be like.
Step 5: Printing the information you find
You can print any WWW page in the usual way.
 Click File on the menu bar at the top of the window.
 Click the mouse button when the highlight is on Print.
 Find and click the OK button on the Print window.

Step 6: Finding your way back to Google
It is quite easy to get lost ‘surfing’ the WWW. You find a link on a
page and you click it to see where it takes you. Suddenly, you
feel lost because you do not know how to get back to where you
were.
There is a simple way to get back to the Google page.
Below File on the menu bar you will find this icon:
 Click on this Back button once to go back to the previous
page.
You can click Back as often as you need to get back to the Google
page.
You could enter key words for a different search when you are
back at Google’s page. However, let’s disconnect from the
Internet so that you can practise all the steps again.
Step 7: Disconnecting from the Internet
This is done in the usual way.
 Click the Explorer menu in the top left corner of the screen,
then click on Quit Explorer at any time. You do not need to be
on your organisation’s home page.
This shuts down the browser in your computer. Your tutor will
show you how to disconnect from the Internet if you need to.
You have now followed the steps that you will use when your tutor
gives you an assessment task.
You should practise these steps so that you can do the
assessment task with confidence. The steps are set out clearly
on the next page.

Extension activities
Now you should make some searches for information that you
really want to know. As you do these searches, remember:

Choose key words as specific as possible and watch the
spelling very carefully.
For example, David Beckham gets results, Beckem won’t.

Some pages may take time to arrive on your screen.

Some pages may not be available because they are being redesigned.
The purpose of this activity is to build your confidence in
searching the WWW. If you have some difficulty, simply try
another search.
Now what information do you want or need? For example, you
could look for information on:
 your favourite singer or group
 your sports hero or team
 the background gossip to a recent film or TV show
 a medical condition that concerns you for some reason
 the latest BBC TV news.
Good searching, whatever you choose to look for.
