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.
