Basic Concepts
Vanguard was generally very similar to the V-System, but added support for true object oriented programming of the operating system. This meant that kernel and server interfaces were exported as objects, which could be inherited and extended in new code. This change has no real effect on the system itself, it is primarily a change in the source code that makes programming easier.
For instance, Vanguard had an I/O class which was supported by a number of different servers, networking and file servers for instance, which new applications could interact with by importing the I/O interface and calling methods. This also made writing new servers much easier, both because they had a standard to program to, as well as being able to share code more easily.

Famous quotes containing the words basic and/or concepts:
“Justice begins with the recognition of the necessity of sharing. The oldest law is that which regulates it, and this is still the most important law today and, as such, has remained the basic concern of all movements which have at heart the community of human activities and of human existence in general.”
—Elias Canetti (b. 1905)
“During our twenties...we act toward the new adulthood the way sociologists tell us new waves of immigrants acted on becoming Americans: we adopt the host culture’s values in an exaggerated and rigid fashion until we can rethink them and make them our own. Our idea of what adults are and what we’re supposed to be is composed of outdated childhood concepts brought forward.”
—Roger Gould (20th century)
