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:
“The research on gender and morality shows that women and men looked at the world through very different moral frameworks. Men tend to think in terms of “justice” or absolute “right and wrong,” while women define morality through the filter of how relationships will be affected. Given these basic differences, why would men and women suddenly agree about disciplining children?”
—Ron Taffel (20th century)
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (1893–1978)
