Every day you open the Internet without thinking about what it really is. In this lesson we separate the Internet from the World Wide Web, meet its services and cloud computing, see how a browser and a search engine work, peek at the HTML tags and forms behind a web page, and finally clear up three confusing words — Internet, intranet and extranet — using real Namibian examples like Bank Windhoek internet banking.
