QuickBASIC is a BASIC compiler/interpreter for DOS and OS/2. It should not be confused with QBasic, which is an interpreter-only version of QuickBASIC 4.5 with a reduced instruction set. An IDE has been included with QuickBasic since version 2.0.
The final product in the QuickBASIC line was QuickBASIC Extended 7.1, also called Microsoft BASIC Professional Development System 7.1 or QBX. (According to Wikipedia's QuickBASIC entry, the QBX IDE did not run under OS/2.)
Microsoft eventually replaced QuickBASIC with Visual Basic. (Visual Basic 1 for DOS can compile most (if not all) QB code unchanged.)
QBasic
QBasic is an interpreter that Microsoft distributed with later versions of MS-DOS. It is based on QuickBASIC 4.5, with the compiler and parts of the language removed. Any program specifically written for QBasic will work under QuickBASIC 4.5 or later without changes.
"Standard"
The QuickBASIC language has become something of a de facto standard, inspiring several later compilers, many of which attempt to be QB-compatible (with varying degrees of success). A few of the modern compilers include:
