Operating system (OS) emulation consists of running a binary executable intended for a particular OS on a different OS. This ability allows users to run more programs and OS manufacturers to jumpstart new OSs with non-native programs. There are several OSs that can run binaries compiled for the same processor but for different operating systems. There are also systems that can run multiple OS s...

The Cnonus technology has been designed for building o'new generations" of open, distributed, scalable Operating Systems. CHoRus has the following main characteristics: ¡ Ír comÍ[tnication-based technology, relying on a minimal Nucleus integrating distributed processing and communication at the lowest level, and providing generic services used by a set of subsystem servers to provide extended s...

• uniform interfaces—same for kernel and user-level services • extensibility—can add new services • flexibility—can subtract/modify services • portability—easier to port operating system because os-specific part is smaller • reliability—smaller kernel makes its implementation likely to be more reliable. Also more well-defined APIs. • distributed system support—pieces can be on another machine. ...

Operating systems provide the fundamental mechanisms for securing computer processing. Since the 1960s, operating systems designers have explored how to build “secure” operating systems — operating systems whose mechanisms protect the system against a motivated adversary. Recently, the importance of ensuring such security has become a mainstream issue for all operating systems. In this book, we...

The course ‘Operating System Internals’ (OSI) usually focuses on teaching the concepts and issues surrounding the design of an OS in general. Students are advised to learn by example and through experiments, which are fundamental for the real understanding of operating system. Although controlled experiments with a commercial OS is one of basic approaches in organizing the practical work of stu...

Computers have brought about a revolution across all industries. Computers have become the most important part for the success of any enterprise. Computers are the best means for proper storage and management of data. They can assist as knowledge bases and can be utilized for financial transactions due to their processing power and storage capacities. PCs handle and keep a track of data which i...

As computers become more powerful it becomes feasible to develop computer models that more accurately approximate the real systems they are simulating. However, such models are increasingly complex, perhaps taking years to develop, so it is important to maximise reuse of existing models and design new models to facilitate reuse. Unfortunately many existing models are not easily reused for vario...

The purposes for the research and development of the RWC massively parallel computer project are (1) to e ciently support exible and integrated computation which are research targets in RWC Project, and (2) to pursue a general purpose massively parallel system e ciently supporting multiple programming paradigms, and (3) to realize a stand{alone system which has a mature operating system. For th...

Microsoft’s Vista (“Vista”) can be seen as a dramatic departure from previous versions of the vendor’s operating systems, in terms of security and file systems. This vendor’s technical advances in security have created problems for law enforcement and other computer forensics investigators. This paper will illustrate how changes to Vista’s file systems will impede the retrieval of inculpatory e...
