Facebook
Facebook is a social utility that connects people with friends and others who work, study and live around them.
The Facebook social network has revolutionised keeping in touch over the Internet. Friends and families can now connect with each other in a network of relationships, sending emails, playing quizzes and games, sharing photos and generally having casual day-to-day contact that is often difficult due to geographical distances and busy lifestyles.
