  • The Internet

    The internet is not a single ‘thing’ that is housed in one location, it is an enormous network consisting of millions of smaller networks, a frame of networks. Billions of computers connected together in a global network. Any computer anywhere in the world can connect to any other computer anywhere else in the world as long as they are both connected to the internet. Information that travels between computers on the Internet does so through a variety of protocols also known as digital languages.

    Internet Access on the Mobile Phones

    World Wide Web

    The world wide web or as it is usually called the Web is how we access information over the internet. The World Wide Web, or simply Web, is a way of accessing information over the medium of the Internet. It is an information-sharing model that is built on top of the Internet. The Web uses the HTTP protocol, only one of the languages spoken over the Internet, to transmit data. Web services, which use HTTP to allow applications to communicate in order to exchange business logic, use the the Web to share information. The Web also utilizes browsers, such as Internet Explorer or Firefox, to access Web documents called Web pages that are linked to each other via hyperlinks. Web documents also contain graphics, sounds, text and video.

    Web Browser

    A web browser is the tool you use to access the World Wide Web in order to search for information, download files, watch streaming videos, etc. There are many browsers but the most common are Internet Explorer, Opera, Google Chrome, Safari and Firefox. You have Microsoft Internet Explorer and we will focus on this browser:All browsers use a Graphic User interface, meaning you can just point and click with your mouse

    Microsoft Internet Explorer

    Open Internet Explorer by clicking on the Start button. Usually the internet explorer icon will be visible as soon as you click on the start button You might also have the internet Explorer icon on your Quick Launch bar, next to the Start button


    Internet Terminology



    A Uniform Resource Locator is the web address that you type in the browser (it tells the browser exactly where to find the page). URL is an acronym meaning Uniform Resource Locator, basically the address of the website you are accessing. A URL can be broken down into various parts. An example would be: www.nemisa.co.za.
    • www – World Wide Web
    • nemisa – Name of the company
    • co - company (alternatives are ac - academic, gov - government)
    You are also able to go a web address by clicking on a link from a different page or by searching for a page in a search engine.

    Navigation Buttons

    If you click on a link that opens, changing the current page, and then need to go back to the original page you can do this easily by clicking on the Back Button (Arrow pointing left). Once you’ve clicked the Back button, you can press the Forward button (arrow pointing right) to follow the link again.

    Refresh & Stop

    When you use the Back and Forward buttons (Navigation Buttons), your browser may use its web cache to display the page. The web cache stores recently-viewed web pages so that they don't need to be downloaded again. That's usually good because it speeds up your web browsing, but sometimes you want to see the most up-to-date information on the page. You can use the Refresh button (sometimes called Reload) to tell the browser to load the page again. If a page is taking too long to load, or if you've typed in the wrong URL, you use the Stop button to stop the page from loading.

    Search Bar

    Most browsers have a built-in search bar for performing web searches. By clicking in the Search Bar, you can just type what you are looking for and then click on search or press Enter. The web page will then reopen with a list of all the search results. Search bars are enabled and linked to search engines. In the image above you will see that we have made use of the Google Search Engine to run our search. You can either click on the search bar located next to the URL bar or you can visit the Google web site. Google hosts country specific sites to speed up browsing and allow you to see and search local content first. Search engines are also available in multiple languages.

    New Tab

    Most of the new browsers allow you to open a link in a new tab. This allows you to keep the current page open, instead of going directly to the new page. For example, if you looked for information in Google about NEMISA, you’ll find thousands of results. You can right-click any of these links, select Open in a New Tab and still retain all the references found by Google Tabs were designed to make the browsing experience more convenient. You can open as many links as you want and they will stay in the same browser
    NOTE: Wording might differ from browser to browser.


    ‘A hyperlink is a word, phrase, or image that you can click on to jump to a new document or a new section within the current document. Hyperlinks are found in nearly all Web pages, allowing users to click their way from page to page. Text hyperlinks are often blue and underlined, but don't have to be. When you move the cursor over a hyperlink, whether it is text or an image, the arrow should change to a small hand pointing at the link. When you click it, a new page or place in the current page will open. Hyperlinks, often referred to as just ‘links,’ are common in Web pages, but can be found in other hypertext documents. These include certain encyclopedias, glossaries, dictionaries, and other references that use hyperlinks. The links act the same way as they do on the Web, allowing the user to jump from page to page. Basically, hyperlinks allow people to browse information at hyperspeed.’

    Search Engines

    On the Internet, a search engine is a coordinated set of programs that includes: A spider (also called a "crawler" or a "bot") that goes to every page or representative pages on every Web site that wants to be searchable and reads it, using hypertext links on each page to discover and read a site's other pages. A program that creates a huge index (sometimes called a "catalog") from the pages that have been read.

    A program that receives your search request, compares it to the entries in the index, and returns results to you.

    So, in basic English, a search engine is a computer program that sorts through the internet and helps you to find information. Since the internet is so vast, unless you had the desired address of the site you wanted to visit you could possible spend days and weeks and even months to finding what you are looking for if you had to do it manually. A search engine automates this. Some examples of search engines are: Google, Bing, Yahoo, MSN, Ask.com and About. Once you have run your search and the page with the results shows on your screen you can link to the page you want by simply clicking on any of the links that appear in blue, you will then open that specific result. Also refer to picture above to see how to open the results in a new tab.
    Web Web
    At the bottom of the web page there will be links to more results. If you click on 2 it will take you to the second result page if you did not find the answer on the first page. All the other numbers indicate more pages with results. If the first page of results did not return what you were looking for, you can then click on one of the other pages to see whether there might be a result that you are looking for.
    NOTE: Search engines look for matching words. If you search for Franschhoek, the search engine will not know whether you are looking for restaurants or accommodation in Franschhoek or whether you want to know more about the history of Franschhoek.
    Web To get the best results, ask yourself: What exactly am I looking for? Specific terms usually return better results.
    NOTE: Search engines may include advertisements along with your search results. These ads are picked by the search engine based on your search terms, and look like the actual search results. These are called Sponsored Links. While it may be useful in some cases, remember that these are only advertisements.

    Downloading Files

    If you click on a link to a file, it may download automatically, but sometimes it just opens within your browser instead of downloading. To prevent it from opening in the browser, you can right-click the link and select Save Target As... (different browsers may use slightly different wording). You will be able to choose the folder where the file is saved.


    In the next window that opens, you can then decide where you want to save the document. Note: Usually it will save documents in your My Documents folder (see example below) In order to open your document you will have to navigate to your My Documents folder, using Windows Explorer and double-clicking the relevant document. Since the process of downloading a file varies from site to site, it may require some trial and error. You will follow the same procedure to download music, movies or pictures from the internet. Note: Some websites do not allow you to download files
