... common types of non-repudiation evidence are the evidence of proof of creation of a message and evidence of proof of receipt. Non-repudiation often involves the participation of a trusted third ... technically designed as a set of capabilities that is built on top of the Windows 2000 operating system. Therefore, the cluster service is not an innate part of the operating system, although the operating ... comparing two similar systems. The choice of operating systems running on the server is critical in determining the scalability of a server system. Quite simply, some operating systems are more...
