Internet Browser
• An Internet Browser is a software program that enables you
to view Web pages on your computer. Browsers connect
computers to the Internet, and allow people to “surf the
Web.”
• Internet Explorer is one of the browsers most commonly
used. There are other browsers available as well, including
Google Chrome.
World Wide Web
• What is the World Wide Web (WWW)?
A Web site is
a collection of
related Web pages
A Web page contains
text, graphics, sound,
video, and links to
other Web pages
You can share
information by
creating Web pages
or posting photos on
a photo community
 Billions of documents, called Web pages, available to
anyone connected to the Internet. The World Wide Web is
a service that is provided on the Internet
• A site or area on the World Wide Web that is
accessed by its own Internet address is called a Web
site.
• A Web Page is like a page in a book. Websites often
have several pages that you can access by clicking on
links. A Web site can be a collection of related Web
pages.
• Each Web site contains a home page (this is the
original starting page) and may also contain
additional pages.
• Different computers will have different home pages.
You can set your own webpage.
Layout of a Web Page
1. Title bar – tells you the name of the web page
2. Menu bar – has commands for moving around the webpage,
printing, etc
3. Tool bar – short cuts to commands. Each picture
represents a command
4. Address bar – webpage address. If you want to go directly
to a web page, you will need to know the address.
Parts of a Web Address
• A web address is typically composed of four parts:
• For example, the address http://www.google.in is made up of
the following areas:
• http://
This Web server uses Hypertext Transfer Protocol (HTTP). This
is the most common protocol on the Internet.
• www
This site is on the World Wide Web.
• google
The Web server and site maintainer.
• in
This tells us it is a site in India.
• Endings of web pages tells us a bit about the page. Some
common endings to web addresses are:
• com (commercial)
• edu (educational institution)
• gov (government)
• net (network)
• org (organization)
• You might also see addresses that add a country code as the
last part of the address such as:
• In (India)
• ca (Canada)
• uk (United Kingdom)
• fr (France)
• us (United States of America)
• au (Australia)
How to Search the Internet
Two basic ways
1. if you know the address of the web page
(example: www.cbc.ca)
2. Using a search engine like Google to find the
address. This is called a keyword search
Typing in the Web Site Address
1. Go to the address bar. Click once to highlight the
address. (It should turn blue).
2. Hit the Delete key on your keyboard.
3. Enter the following address:
www.theweathernetwork.com
4. Then press Enter on the keyboard or click on the
word Go on the right side of the Address Bar.
Search the Internet
• If you don’t know the address of the webpage, but
want to learn more about a topic or find a
particular website, you will need to do a search.
• There are several handy search engines out there
that will locate information for you. Two of the
mostly commonly used are:
www.google.com
www.yahoo.com
Practice Exercise
1. Type www.google.ca into the address bar.
(www.google.ca is a Canadian version of the
search engine. www.google.com will search
US sites first)
2. Hit the Enter key or Go on the toolbar. You
should see the Google web page.
3. Now click on the Google box. You should see
a flashing cursor. Type in the topic. Hit enter.

Basic Computer Terms and Definitions
Desktop: The first screen that you see when any Windows operating system screen is up and
running. One of the main purposes of the Desktop is to make it easier to access different
application programs, files and documents.
File: Unit for storing information that may include a word-processing document, a spreadsheet,
a picture, a graphic, musical piece, or even part of an application program. Examples of
"files" include text files which could be a letter or report and graphic files which could be a
picture. Each file has a name because the data or information created in a software program
is saved with a file name.
Folder: Method for organizing files that is related by topic, by purpose, by type, by program, or
even by a project that you are working on. NOTE: When an application program is loaded
onto your computer, it will group similar applications in a folder. As you add or create files,
you can organize them however you want.
Hyperlink: Allows you to move from one web page document to another. It can be text which
is usually underlined or a graphic. When you move your mouse over a hyperlink, the
mouse cursor usually becomes a hand which indicates a hyperlink is present. Once you
click on the link, you move to another web page document or to another place on the
same web page.
Icon: A small picture that represents processing options such as programs, documents, and
shortcuts. When you click on the icon, the file or program will open. The most easily
recognized icon is the Recycle Bin which is the graphic below.
Input: Commonly known as data and refers to numbers, letters, words, images, video, music
and even sounds. Other computer input includes commands and user response. A
command directs the computer to execute tasks or perform certain activities. One
example of a command is a command buttons OK, Cancel and Help seen on the Shut Down
Windows dialog box.
Internet: A world wide network that connects millions of computers to share and exchange
data, news, opinions, and research results. The Internet is not the same as the World Wide
Web (WWW). The World Wide Web is a service that is provided on the Internet.
Keyboard: The keyboard is an input device that allows you to enter letters, numbers and
symbols into your computer. The keyboard keys include the alphanumeric keys (letters and
numbers), numeric keypad, special function keys, mouse cursor moving keys, and status
lights.
Files and Folders: Think of a computer folder as being similar to a filing cabinet folder, whereas a
computer file is similar to the pieces of paper that are placed in the folders.
Graphic User Interface (GUI): Combines text and graphics to make software easier to use.
Graphical User Interface features include icons, windows, menus, and buttons.
Hard Copy: Usually refers to a printout on paper.
Hard Drive: The purpose of the hard drive is to store information. This device that allows the
computer to permanently retain and store data like the operating system, programs and
information data. The hard drive holds more data than a diskette and accesses information
faster than on diskettes. Storage refers to the capability of storing things, and as for the
computer, it is information.
Menu: List of options that may be commands or other options from which you can choose from.
The following illustration is the File Menu Bar command menu list.
Mouse: Besides a keyboard, a mouse is the most common input device for a computer. The
mouse is a small, palm-sized input device that you move across a flat surface, such as a
desktop, to control the movement of the pointer on the screen. Technically, there are many
operations that are much easier to perform with a mouse than a keyboard because you can
just point and click to select an item on a screen or choose an item from a list of options.
Mouse Commands: Before examining the various commands, you must understand how to
execute each mouse command. The mouse commands include move, point, click, deselect,
double-click, drag, and right-click.
My Computer: An icon that opens into a folder of icons for all of the resources on the computer
like the hard drive and printer.
Operating System: Software that acts as an interface between you, the application software (like
word processing or accessing the Internet), and the computer components. This includes
interpreting and carrying out basic instructions that operate a computer like recognizing
information from the keyboard and mouse, sending information to the monitor, printer, or
speakers and scanners, storing information to the hard drive and removable drives. Common
operating systems include Windows XP, Windows 2000, Windows ME, and MAC OS.
RAM: This is an acronym for Random Access Memory. This memory is a work area or a
temporary storage space where the computer places program information so that it can
execute the program instructions and information. When the program or file is closed, the
data or programs are removed from RAM. The amount of RAM you have on your
computer is crucial in determining how many programs can be opened (running) and how
much data is available for each program. RAM is available in MB or megabytes. An
example is 256MB of RAM.
Select: A single left mouse click to select a file or folder icon.
Software: Instructions that provide the computer with step-by-step actions that need to be
executed to complete a specific task. A computer will not function with software.

Examples of "files" include text files which could be a letter or report and graphic files which could be a picture. Each file has a name because the data or information created in a software program is saved with a file name. Folder: Method for organizing files that is related by topic, by purpose, by type, by program, or even by a project that you are working on. NOTE: When an application program is loaded onto your computer, it will group similar applications in a folder. As you add or create files, you can organize them however you want.
  • 42. Hyperlink: Allows you to move from one web page document to another. It can be text which is usually underlined or a graphic.

Icon: A small picture that represents processing options such as programs, documents, and shortcuts. When you click on the icon, the file or program will open. The most easily recognized icon is the Recycle Bin which is the graphic below. Input: Commonly known as data and refers to numbers, letters, words, images, video, music and even sounds.

Common operating systems include Windows XP, Windows 2000, Windows ME, and MAC OS.
  • 45. RAM: This is an acronym for Random Access Memory. This memory is a work area or a temporary storage space where the computer places program information so that it can execute the program instructions and information. When the program or file is closed, the data or programs are removed from RAM.
