Dropbox, how does it work?

If someone send me a link to data stored in a dropbox account.

How do I access it, if I dont have my own drop box account?

As the link posted by Tomsk says, the file/data you are being given would be in a Public folder. The owner of the file/data would then make a link that they'd send you. Using that link would allow you access to the file.
