Facebook is a social networking site.  It allows you to create an electronic group of friends. 

Users create a profile. They then populate with their interests, activities, geographical location, schools, jobs etc.  They can also upload their photos and videos. People that are not currently in your friends list can only see basic information about you, unlike sites like Friends Reunited.

The network is created when you invite people to be your friend.  Facebook, as with most social networking sites requires both parties to confirm that they are friends.  Once someone is your “friend” they can then view your profile that you created on-line.  You can put as much or as little information in as you want.

Once you have created your profile, you can then invite people to be your friend, join groups, networks or discussions which interest you and make new contacts.

Facebook can be used to create a basic webpage to keep in touch with your friends, share interests, photos, files and events.
