CD/DVD
Floppy Disk
The hard drive is inside the case. A lot of information can be stored there, but it is not
portable.
Flash or USB drives can hold quite a lot of data and are a safe way to transport your
documents. The biggest danger is probably misplacing them.
CDs hold more information than a floppy. (A 650 MB CD is equal to approx. 450 floppy
disks)
Floppy disks are an old technology but can still be used in older computers. New
computers do not automatically come with floppy drives anymore.

Websites
You now have all the basic skills you need to start looking at websites and surfing the internet!
The Internet – Lots of computers, all over the world, connected and able to communicate with
one another. This makes e-mail, surfing the web and online chatting possible. Information
available via the internet that can be displayed visually by a “web browser” is called the “World
Wide Web” (i.e. web sites).
Web Browsers – Programs (software applications) on your computer that allows you to view
web sites. Examples of browsers include Microsoft’s Internet Explorer, Mozilla’s Firefox,
Google’s Chrome and Apple’s Safari.
Hyperlinks – Clicking your Way to More Web Pages:
Hyperlinks are text or pictures on a web page that can
be clicked on to take you to another web page. Words
that are hyperlinks are often (but not always) a
different colour than their neighbours and they are
sometimes underlined.
You can tell when your mouse is over a
hyperlink because the mouse pointer will
become a hand.

Finishing Up for Today
We hope you’ve enjoyed your introduction to computers!
FINAL EXERCISE: Shutting
Down the Computer
Shutting Down the Computer
Whenever you’re finished using a computer you should shut it
down. For the computer it’s a bit like tidying up your desk and
filing important papers away so you can find them again.
Practice is Essential!
The only way to improve your computer skills is to practice
what you have learned. If you don’t have a computer at home
you can use the library computers to practice.
Here are the website addresses for two excellent tutorials.
Use them to perfect some of your new skills. (The library’s
information desk staff can help you to get to these exercises.)
• www.mesalibrary.org/research/mouse/page01.htm
• www.pbclibrary.org/mousing
1. Single left click the Start
button, click Shut down. A
little window will open.
2. Click Shut down. Click OK.
3. Your computer will start
shutting down and switch
itself off. (If you see a
message saying “It is now
safe to turn off your
computer” you can push
the power button to turn it
off.)
