1.2 communication

communicatons has been a key focus of change in the information age. The way most businesses and young people communicate in the 21st century has changed enormously from the way their parents and grandparents communicated in the middle of the 20th century. Email, chat, sms and digital voice and mobile videophones have rapidly become the way to communicate. We communicate much more, more quickly and more globally. One of the internets kiler applications has been Email. In 2001 it was estimated that 12 thousand million messages were sent daily and by 2003 there were 31 thousand milion sent daily, and by 2005 it has estimated that 75 thousand million messages are sent daily now, the reasons for this is because eamil has massive benefits for induviduals and businesses. One of the major benefits of email is the relatively low cost to the user of sending messages. A consistant theme of the developing internet, however, is that providers are trying to find ways of charging for services that have traditionally been free and email may not always be quite as free as it is at this moment. One of the major drawbacks is spam, or junk mail. Most estimates suggest that between 30 percent and 40 percent of email is junk mail or spam.
