What happens when initial/next extents are taken?

I do have a conceptual problem -- actually I have a doubt about how the process for Oracle works when initial and next extents are already taken. So does Oracle search for contiguous disk blocks or just for free space at the tablespace?

An extent must occupy contiguous space in your tablespace's datafile. When an extent is allocated (initially or subsequently), Oracle must find enough contiguous free space for that extent. Once if finds that space, the extent is allocated. If there is not enough contiguous free space, Oracle will give you an error.
