          1.2 Communicating on Internet

          Communication is the most popular use of the Internet, with email topping the list of all the
          technologies used. Some of the types of communication technologies used also include email
          discussion groups, Usenet news, chat groups, and IRC. These are unique to networked computer
          environments and have come into wide popularity because of the Internet. Other technologies,
          including video and audio conferencing and Internet telephony, are also available on the Internet.
          They require more multimedia capabilities of computer systems and are more taxing of network
          resources than the others. They also are adaptations of other technologies to the Internet.
          Most of the technologies that are unique to the Internet require communication to be done in
          text—letters with some symbols and punctuation.




             Notes   Communicating  effectively  involves  taking  the  time,  except  in  informal
             communications, to use correct  grammar, spelling,  and  punctuation  and  writing  an
             appropriate message.  When replying to a message include the pertinent  parts of the
             message and use an appropriate and interesting subject header in any case.

          authority, or control on the Internet. Domain names are formed by the rules and procedures of
          the Domain Name System (DNS). Technically, any name registered in the DNS is a domain
          name.
