Is Visual Basic just a programming language or is it more than that?

It's more. Visual Basic was one of the first systems that made it practical to write programs for the Windows operating system. This was possible because VB included software tools to automatically create the detailed programming required by Windows. These software tools not only create Windows programs, they also take full advantage of the graphical way that Windows works by letting programmers "draw" their systems with a mouse on the computer. This is why it's called "Visual" Basic.

Visual Basic also provides a unique and complete software architecture. "Architecture" is the way computer programs, such as Windows and VB programs, work together. One of the major reasons why Visual Basic has been so successful is that it includes everything that is necessary to write programs for Windows.
