Difference between System Testing & Functional testing ?

[TGS Expert]

In a general sense, the term 'system testing' refers to the
testing of the system to ensure that it should perform as expected and
as required. Testing is performed module by module and also as a
whole. System Testing does not concern itself with the functionality of
the system and whether this is appropriate to meet the needs of the
users.

Whereas Functional Testing is to ensure that all the functionality in
the applications can perform correctly under all of the conditions that
the application could encounter when used in live processing.
