A comparative study of technologies developed in perspective of distributed operating systems

The collection of processors that do not share memory and clock is called distributed operating system. It is an infrastructure which is programmed so that it allows the use of multiple workstations as a single integrated system. In distributed OS users can access remote resources as they access local ones. The advantages of distributed operating systems are performance through parallelism, reliability and availability through replication and in addition scalability, expansion and flexibility of resources. This research paper includes a detailed and comparative introduction of different state-of-art technologies and operating systems, their internal structure, design and key features which are developed in perspective of distributed operating systems. These operating systems includes Chorus, V-systems, Amoeba and Mach.
