system as a set of independent system servers using the primitive, generic services of a microkernel. Compared with traditional operating systems, the micro-kernel approach adds two new aspects to the low-level kernel foundation: distribution and subsystem support. In other words, this technology adds to the traditional monolithic architectures the necessary modularity, key to their evolution, introducing the object oriented approach to operating system design. The micro-kernel provides a virtual

CHAPTER 6 6.4) John von Neumann, usually considered the developer of the computer as we know it today, set down a series of guidelines known as the von Neumann architecture for computers. The major guidelines include: Memory holds both programs and data which is known as the stored program concept. This allows programs to be changed easily. Memory is addressed linearly- there is a single sequential numeric address for each and every memory location. Memory is addressed by the location number without

There is now an identifiable trend in industry toward downsizing that is replacing expensive mainframe computers with more cost-effective networks of personal computer that achieve the same or even better results. This trend has given rise to the architecture of the Client/Server Computing. The term Client/Server was first used in the 1980s in reference to personal computers on a network. The actual Client/Server model started gaining acceptance in the late 1980s. The term Client/Server is used to describe
