unique visitors exact defination

guy i little confused regarding the meaning 'unique visitors'. so please tell me exact difination unique visitors.

 

Unique vistor is one person. It is basicaly how many new people see the site. Some stats list unique as 24 hours. So if someone goes to your site 5 times it only counts as 1 unique vistor in 24 hours. If they come back after 24 hours they are unique vistor again.

Some stats let you set time before any repeat vistors is counted as unique. I hope this helps figureing it out.

 

Oh, looks like rcj662 has said it all
