Difference between unique visitors and users

General questions

Hello,

I have a problem. I can’t understand why the number of users is different of the number of unique visitors.
Does someone can explain me ? Is it a problem on my tracking ?

Thanks in advance.

Ok here what I know:
the visitors are the visits from a repeated returned visitors, unique visitors are the visits which came from users they never been in your site before.

for example when you visit your website it means a visit
but if i visit your website its unique visit since this is my first time I visited your site.

I hope this was useful information
