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.
