  1. Dinosaurs During this unit you will be briefly covering several different topics to give you a taste of ICT. The overall aim of this unit is to create an interactive powerpoint about Dinosaurs... The first topic is searching the internet

  2. Search Engine A database on the World Wide Web that enables you to use search terms or key words to find relevant pages or websites. Examples include Google, Bing, Ask

  3. Keywords Keywords are the terms in a webpage that would be used to match the search term a user enters into a search engine. If you search for ‘ICT’ then the search engine will find you every page on the web that has ‘ICT’ in the body text, the header and the tags.

  4. Search engine results On your ‘Search Results’ page, find and label the following items: The search term used The number of results found How long the search took to return your results The title of the one of the search results The snippet of text which gives you a quick overview of the content of the page Related searches that you could try More pages of your results Images of search topic The URL (web address) for a search result

  5. Searching for Information

  6. Searching For Information • During this and next lesson, you will be finding out about some of the following things: • What a URL means • How to search for information effectively on the Internet • How to make sure that the information you find is accurate • How to choose appropriate information to help you develop a presentation about a given topic.

  7. Different Search Engines We now recognise the different parts of a search engine, but do all search engines return the same results? Have a look at the table on the next slide...

  8. Different Search Engines

  9. Different Search Engines Now we know that different search engines return different results, lets get some first hand experience Complete the Different Search Engines worksheet from the ICT SoW

  10. Uniform Resource Locators Lets take it a step further now and start to look at the what a URL is...

  11. Uniform Resource Locators For you to stand any chance of finding what you want on the Internet, there has to be an easy way to locate a particular web page. Luckily every single one of those billions of web pages has its own unique address – a bit like you have your own unique address at home. These web page addresses have a name – they are called ‘Uniform Resource Locators or URL for short.

  12. Uniform Resource Locators (URLs) These are some examples of the URLs that you may have come across: http://www.google.com http://www.facebook.com http://www.amazon.com If you type these URLs into your browser, you will go to the exact site you wanted without having to use a search engine.

  13. Uniform Resource Locators (URLs) A URL can often tell you a lot about a website before you even visit it. http://www.amazon.co.uk http means the protocol used Protocol is the way that two computers have agreed to ‘talk’ to each other. There are many different protocols available. For web pages, the method used is called HyperText Transfer Protocol or HTTP.

  14. Uniform Resource Locators (URLs) http://www.amazon.co.uk The www is short for World Wide Web. The www in the URL does not really do anything, it simply grew out of popular use. You will now find many websites which do not have ‘www’ in their URL.

  15. Uniform Resource Locators (URLs) http://www.amazon.co.uk Amazon.co.uk is called the Domain name. It is part of the URL. However, it also tells you which organisation owns the site. In this case, a company called Amazon.

  16. Uniform Resource Locators (URLs) http://www.amazon.co.uk Notice that part of the URL contains the word .co This can tell you a lot about the type of website that you will be visiting. In this instance, it means that the website belongs to a company or business.

  17. Uniform Resource Locators (URLs) Other URL endings that you may come across: .govGovernment site .comInternational company .coCompany .orgOrganisation (often a charity) .acAcademic – often a university .schSchool .edEducation .netNetwork of websites

  18. Uniform Resource Locators (URLs) http://www.amazon.co.uk Finally, notice that this URL ends with ‘.uk’ This means that the website is registered in the United Kingdom. A website which ended with: .fr would mean it was registered in France .cn would be registered in China .nz would be registered in New Zealand

  19. Uniform Resource Locators (URLs) Lets put your knowledge of URL’ to the test, have a go at completing the URL’s worksheet from the ICT SoW
