There is no difference in meaning between someone and somebody , but somebody is more common in spoken English, and someone is more common in written English.
You don't usually use 'someone' or 'somebody' as part of the object of a negative sentence. Don't say, for example, ' I don't know someone who lives in York '. You say 'I don't know anyone who lives in York'.
In questions, you can use someone , somebody , anyone , or anybody as part of the object. You use someone or somebody when you are expecting the answer 'yes'. For example, if you think I met someone, you might ask me 'Did you meet someone ?' If you do not know whether I met someone or not, you would ask 'Did you meet anyone ?'
