It was envisaged as a communications system to be used in a national emergency. • The first Internet went "live" in 1969 with two sites, UCLA and SRI (Stanford Research Institute). The Internet originated as the realm of the military, research centres, universities and government who identified its data transporting capabilities as significant. • In the 1980s the use of computers became more widespread. In 1989, Compuserve (now run by America Online) and MCI Mail provided the first commercial email connections to the Internet.

  18. Hyperlinks • Hyperlinking is a way of moving between website pages • The text to be hyperlinked is recognizable by being underlined or a different colour • Images or a combination of text + image can also perform hyperlinks

  19. Web browsers are programmes used to explore the Internet

  20. Email for beginners

  21. What is email? • Electronic mail or e-mail is one of the most popular uses of the Internet. • With an e-mail account you can send an electronic message (much like a letter) to anyone with an e-mail account but you need to know their e-mail address. • An e-mail address looks like this: your username, then an @ ('at') symbol, and then a domain name (something .com, .net, or .org in most cases). E.g. szinn@uwc.ac.za

  22. Setting up a account • Type the URL “gmail.com” in the address bar • Select (click on) “create an account” • Have your diary or cell phone handy to record the user name and password you decide to choose • Complete the online format and submit • You will receive a welcome message from Gmail

  23. Sending an email • Select “Compose mail” • In the “To” field, enter the recipient’s email address • In the “Subject” field type a heading describing the gist of the email • The space below is the area where you type your message much like a letter • When completed you select the “send” button

  24. Other options and fields • “Attach a file” option allows you to attach documents, images or any files saved on your computer • CC stands for carbon copy & is used if you want to send a message to multiple people, add the extra addresses in the CC field separated by commas • BCC stands for blind carbon copy. BCC works just like a carbon copy, except the e-mail addresses you type in BCC cannot be seen by recipients.

  25. Netiquette • Never send an email in CAPITAL LETTERS only. It is the equivalent of shouting • When communicating with people not your closest friends address them with respect. Use complete sentences with proper capitalization and punctuation. Refrain from using shorthand abbreviations, such as “u” for you. • Refrain from flaming (bashing) - hostile and insulting interaction between Internet users • Don’t use emoticons with people you don’t know well.

  26. Search Engines

  27. Search Engines - Introduction • A collection of programs that gather information from the Web, index it, & put it in a database so it can be searched. • Search engines take keywords or phrases you enter, search the database for words that match the search expression, and return them to you. • The results (called hits)are hyperlinks to sources that have descriptions, titles, or contents matching the search expression.
