Usted ( abbreviated Ud.) and tú both mean you. Both are singular. You use tú, the informal singular, for close friends, people younger than you (by a generation, not just a year or so), your pets (Sit! Stay!), and anyone who invites you to use tú. Usted is the formal singular. Anyone who signs your paycheck is Ud., someone you've just met, anyone older than you, anyone giving you service (travel agent, police officer, salesclerk, etc.) unless you are asked to use the tú form. By the way, each of these has a plural. For tú it's vosotros, which is used in Spain but not too frequently elsewhere. For Ud., it's ustedes (Uds.) which is also used as the default for a plural tú. Argentina has the "vos" form, but it's distinct from all of these.
"Tu" is intimate - a close friend, relative, or your girlfriend/wife. "Usted" is proper - an adult you are not formally acquainted with, or don't know well, or someone superior to you (boss, police officer).
'tu' is singular AND informal; it is used for addressing one person only, and used informally, so you use tu with your family, or with friends, but not when talking with your boss or your teacher.
'vous' is plural OR formal. You use it when adressing several persons (like 'you guys' or 'you'all'), or when talking formally to an individual (someone with a different rank, or when the person is much older, ...)
usted is manly used in older people or to show respect it the polite way to say you, and tu is for people you have much more confidence
It is the plural of "you". There is another less used form, the familiar plural, or "vosotros".
