Savoir 

Savoir is usually used with a clause; that is, a group of words including a conjugated verb. These clauses can be introduced by words like que, qui, quand, où, combien, ce que, ce qui, etc., to express the knowledge of facts (i.e. I know that/who/when/where...):

Je sais qu'il vient ce soir.I know that he's coming tonight.

Il sait ce que tu veux.He knows what you want.

Tu ne sais pas qui l'a fait.You don't know who did it.

Ray sait combien d'allumettes il y a dans la boîte.Ray knows how many matches there are in the box.

Elle ne sait pas où elle va.She doesn't know where she's going.

Ils savent à quelle heure le magasin ferme.They know what time the shop closes.

Je ne sais pas ce qui se passe.I don't know what's going on.

Savoir can also be followed by an infinitive to express how to do [something], which can be equivalent to can do [something] in the sense of having a skill.

Il sait jouer aux échecs.He knows how to play chess.  
He can play chess.
