db_block is the Oracle block size. Usually it is the size of the OS block or a multiple of it. Extent is a group of db_block together. Everytime Oracle expands the size of an object. It will get a group of db_block (which is a extent). And the size of the extent (no. of db_block) that it will try to get is specified when you create the object.
