Social networking websites have
changed the way that we
communicate. They allow people to
communicate interactively in real
time anywhere in the world. Groups
of likeminded people can share
information, opinions and interests

broadband connection. Social
networking provides a great way of
staying in touch with friends and
business contacts.
Instant messaging

message that is sent quickly • viruses
can be spread by instant messaging.

internet-only conversations, there is no additional cost at
either end. Skype™ is an example of a service that uses
VoIP. Being able to contact relatives and business
colleagues on the other side of the world at relatively low
cost is the biggest benefit. VoIP software is often used by
businesses for online conferences and meetings. This
reduces travel costs, travel time (and therefore loss of
productivity during this time) and the cost of hiring a
venue. As with all new technology, VoIP has its limitations:
• Reliability. VoIP service is dependent on the quality and
reliability of your broadband service and may not work if
there is a power cut. • Voice quality. Voices can sometimes
be distorted or there may be long pauses between
questions and answers. • Security. As with all internet
technologies, identity theft, viru
