What does the biography of the Prophet mean?

Biography of the Prophet is the collection of the whole life of the Prophet (pbuh) from before his birth to after his death. All events directly related to him, information about his blessed body, information about his morals and attitudes are handled by paying attention to timing. It is not a primary source of religious knowledge for matters related to faith and worship. These and similar issues are dealt with in the books titled hadith / sunnah.
