The ubuntu installer uses parted - for the most part; The parted program in turn uses fdisk to create and modify partition tables and mkfs to create file systems.

GParted and its equivalents are merely front-ends to the linux partitioning tool kit. The Ubuntu installer is the same. It's a layer on top of parted and it executes it in the background, providing an easy to use abstraction of the plumbing behind it. The installer uses other programs, like resize2fs -to resize file systems - directly as well.

Parted does not use fdisk or mkfs. – psusi Mar 9 '12 at 19:52
