Your Facebook profile is a web page other members will see if they look you up. It gives people an idea about who you are and what your interests include. There you can upload your picture. Facebook assumes that many of the people with whom you will want to connect work for the same company, went to the same school or live in the same town as you. To make it easier to find friends, Facebook gathers information about you and everyone else. It does it to create a dense network of contacts. The upside is that you will be able to see old classmates or coworkers who have Facebook accounts. The downside is that everyone else in that network will be able to find you. You can choose not to answer questions if you don’t like them. You may also not accept invitations to become friends if you do not want to and just follow posts on the wall.
