It is a social network like Facebook, except better.

 

[B. Diddy]

Perhaps Google can explain it to you in more detail: Share and discover, all across Google - Google+

You can connect with friends, make new friends, join a community that shares the same interests, post pictures and videos, get news updates and updates from your favorite celebrities, and about a zillion other things. It's intimately connected with all of your other Google services, making it easy to share items from your Google account, or things you see on websites.
