     one you think shows the best results, and you then see which
     answers are from which engines.

Secondary : Web Literacy(Video)

    This programme reveals the critical importance for teachers to
    provide guidance to their pupils when using the internet for
    A group of Year 9 pupils at Wortley High School in Leeds are
    asked to look at three websites. The subject matters are Martin
    Luther King, the holocaust and Victorian robots.
    None of the websites are what they seem. The first two are
    fronts for racists and holocaust deniers. The last is a good-
    natured spoof. None of the pupils spot any problems with the
    validity, reliability or authority of the sites and many say they
    would cut and paste information from the sites for use in
    homework or other projects.
This website was developed to arm you with information so you
don‟t fall victim to these Internet scam artists. Education, good
judgment, and a healthy dose of skepticism are the best defenses
against becoming a victim. Remember, if it looks too good to be
true, it probably is!


                How to read a web address
   First, you need to know how to read a web address, or URL
(Universal Resource Locator). Let's look at the URL for this tutorial:

• "http" means hypertext transfer protocol and refers to the
    format used to transfer and deal with information
• "www" stands for World Wide Web and is the general
    name for the host server that supports text, graphics,
    sound files, etc. (It is not an essential part of the address,
    and some sites choose not to use it)
• "sc" is the second-level domain name and usually
    designates the server's location, in this case, the
    University of South Carolina
• "edu" is the top-level domain name (see below)
• "beaufort" is the directory name
• "library" is the sub-directory name
• "pages" and "bones" are folder and sub-folder names
• the second "bones" is the file name
• "shtml" is the file type extension and, in this case, stands
    for "scripted hypertext mark-up language" (that's the
    language the computer reads). The addition of the "s"
    indicates that the server will scan the page for commands
    that require additional insertion before the page is sent to
    the user.

Here is a list of the domains that have been in operation for the past several
                    years and are generally accepted by all:
•   .edu -- educational site (usually a university or college)

•   .com -- commercial business site
•   .gov -- U.S. governmental/non-military site
•   .mil -- U.S. military sites and agencies
•   .net -- networks, internet service providers, organizations
•   .org -- U.S. non-profit organizations and others

        Country codes (sample) - 2 letter extensions:
.ae – United Arab Emirates
.af – Afghanistan
.aq – Antarctica
.at – Austria
.au – Australia
.ca – Canada
cn – China
.cu – Cuba
.cz – Czech Republic
de – Germany
.fr – France
.uk – United Kingdom
.ge – Georgia
.hk – Hong Kong
.il – Israel
.in – India
.iq – Iraq
.ir – Iran, Islamic
.it – Italy
.ke – Kenya
.kh – Cambodia
.kz – Kazakhstan
.lr – Liberia
.np – Nepal
.pk – Pakistan

.rw – Rwanda
.sa – Saudi Arabia
.sd – Sudan
.se – Sweden
.si – Slovenia
.tr – Turkey
.uk – United Kingdom
.us – United States
.vn – Vietnam
.zw – Zimbabwe

Terms you want to exclude (-)
Attaching a minus sign immediately before a word indicates that you do not
want pages that contain this word to appear in your results. - should
appear immediately before the word and should be preceded with a
space. For example, in the query [ anti-virus software ], the minus sign is
used as a hyphen and will not be interpreted as an exclusion symbol;
whereas the query [ anti-virus -software ] will search for the words 'anti-
virus' but exclude references to software.

           Why Did The American Colonists Revolt?
                               Thomas Ash

•   A complex mythology has been built up around the
    American Revolution: it is a national story of great
    significance to the way the United States views itself.
    But the mythology is just that - a mythology. Contrary to
    the picture presented in American primary schools,
    the Americans were not a separate, turkey-eating
    people, subjugated by the cruel, tyrannical and
    essentially foreign British. In fact, many colonists
    thought of themselves as British. Historians accept
    that the American Revolution had a wide variety of
    motives and causes: these included slightly differing
    political traditions, the economic interests of both parties,
    the trading interests of those directly or indirectly involved
    in transatlantic commerce, the large debt Britain had
    accumulated in the wake of the Seven Years War, and a
    fair amount of mutual misunderstanding as well.

    Improve Your Search Experience
•   In addition to providing easy access to billions of web pages, Google
    has many special features to help you to find exactly what you're looking
    for. Some of our most popular features are listed below.

•   Weather To see the weather for many U.S. and
    worldwide cities, type "weather" followed by the city and
    state, U.S. zip code, or city and country.

    Example:     weather San Francisco

•   Stock Quotes To see current market data for a given
    company or fund, type the ticker symbol into the search
    box. On the results page, you can click the link to see
    more data from Google Finance.

    Example: CSCO
               Keep track of the stocks

•   With the booming stock market it is very important to
    track the stocks on a day to day basis. Putting a stock
    ticker in the search box is the most obvious thing you
    would think of. But it is not always you would remember
    the stock ticker, you should add the keyword “stocks:” to
    the company name.
•   The best part of the obtained result is that it provides a
    chart which shows the trend in the company‟s stock
    along with important statistics.
•   stocks: INFY
•   Note: Currently the results are restricted to the
    companies listed in the US stock markets.
•   Time To see the time in many cities around the world,
    type in "time" and the name of the city.

    Example: time London

•   Calculator To use Google's built-in calculator function,
    simply enter the calculation you'd like done into the
    search box.

    Example: 5*9+(sqrt 10)^3=

•   Unit Conversion You can use Google to convert
    between many different units of measurement of height,
    weight, and mass among others. Just enter your desired
    conversion into the search box and we‟ll do the rest.

    Example: 10.5 cm in inches

•   Dictionary Definitions To see a definition for a word or
    phrase, simply type the word "define" then a space, then
    the word(s) you want defined. To see a list of different
    definitions from various online sources, you can type
    "define:" followed by a word or phrase. Note that the
    results will define the entire phrase.
    Example: Define philosophy

•   Currency Conversion To use our built-in currency
    converter, simply enter the conversion you‟d like done
    into the Google search box and we‟ll provide your answer
    directly on the results page.

•   Example: 150 GBP in USD

•   Fill in the Blank Sometimes the best way to ask a
    question is to get Google to „fill in the blank‟ by adding an
    asterisk (*) at the part of the sentence or question that
    you want finished into the Google search box.

    Example: Isaac Newton discovered *
                    Scholarly Search
• For this use the Google scholar search. But suppose you
  don‟t like to switch to Google scholar search you can add
  the same query with an additional parameter to the
  normal Google search box,
• service oriented architecture filetype:pdf site:edu
            Meanings of any word in an instant

•   Just use the define: keyword. The meaning would of
    course be displayed but also a set of other links which
    might have an alternative definition are also given out
    with the link to read more about it.
•   define:beureaucracy

      Google Gulp

    At Google our mission is to organize the world's
    information and make it useful and accessible to our
    But any piece of information's usefulness derives, to a
    depressing degree, from the cognitive ability of the user
    who's using it. That's why we're pleased to announce
    Google Gulp (BETA) with Auto-Drink (LIMITED
    RELEASE), a line of "smart drinks" designed to maximize
    your surfing efficiency by making you more intelligent,
    and less thirsty.
