Correct.  The limit is 4 primary partitions per disk.  The number of
logical partitions is, effectively, unlimited, because a logical
partition chain is formed using a linked list.  Logical partitions must
be created "within" an extended partition.  Most implementations limit
the possible number of extended partitions to 1.  Extended
partitions are logically similar to BSD disk slices.

Somewhat.  It depends on the system design, OS, and boot software.  In
most cases, what is used is similar in principal (but not
implementation) to extended/logical partitions.  It's really to vague a
question to answer specifically.  Most high-end systems will support
some form of volume management.

Volume Management systems (e.g. LVM, EVMS) solve some problems and
introduce others.  The largest problem they introduce, in my opinion, is
additional administration complexity.
