Starting Internet Explorer In order to get connected to the WWW, we are going to open the Internet Explorer program. Do this now by double-clicking on the Internet Explorer icon on the desktop. Throughout this training, Internet Explorer will also be referred to as Explorer or IE. A screen similar to the picture below should appear: Address Bar and URL
Favorites (Bookmarks) As you use the Web, you will find sites that you want to re-visit. You do not have to write down the URL for those sites. You can use Explorer to save your favourite URLs for you in the Favourites folder. To do this, once you arrive at a site that you want to save, click on: 1. Favorites 2. Add to Favorites The term ‘Favorites’ is often used interchangeably with ‘bookmarks’; saved URLs are, in fact, better known as bookmarks.
Links Links or hyperlinks are usually words or pictures in a document or Web page that connect to another document or Web page. Links are usually underlined or in a different colour than the regular text in the Web page so that it is easy to spot.

Clicking on the downward pointing black triangle will scroll down. Clicking on the upward pointing black triangle will scroll up. You can also pick up the sliding button in the middle of the triangle buttons and reveal more of the screen that way.

CRITICAL EVALUATIONWhy Evaluate What You Find on the Web? Anyone can put up a Web page about anything Many pages not kept up-to-date No quality control most sites not “peer-reviewed” less trustworthy than scholarly publications no selection guidelines for search engines

Search Services Web Portal A Web portal is a single point of access to information which is Linked from various logically related internet based applications and of interest to various type of users Portals present information from diverse sources in a unified way. They provide an excellent way for enterprises to provide a consistent look and feel with access control and procedures for multiple applications, which otherwise would have been different entities altogether. Examples are Yahoo, MSN
Search Services How do search engines work? Search engine databases are selected and built by computer robot programs called spiders – crawling on the WWW. They cannot think or type a URL or use judgment to "decide" to go look something up and see what's on the web about it. (Computers are getting more sophisticated all the time, but they are still brainless.)
If a web page is never linked to in any other page, search engine spiders cannot find it, unless its URL is sent to the search engine companies as a request that the new page be included. After spiders find pages, they pass them on to another computer program for "indexing." Text, links, and other content in the page are stored in the search engine database's files so that the database can be searched by keyword and whatever more advanced approaches are offered, and the page will be found if your search matches its content.
Ranking of websites Word proximity and placement Popularity - a link to a page is a vote for it Importance - traffic, popularity of pages linking to a page Subject specific Some types of pages and links are excluded from most search engines by policy. Others are excluded because search engine spiders cannot access them. Pages that are excluded are referred to as the "Invisible Web" -- what you don't see in search engine results.
