Further, fault tolerance was migrating to dependability (Jean Claude Laprie was an indisputable authority and expert in this domain, see more: which later emerged as the concept of resilience.
In principle, all these new properties had a concrete reasoning and meaning behind them: when something erroneous has happens, any system of our design should be able to cope with the problem.
In this paper we try to evolve an optimized scheduling algorithm by reducing the seek time, the rotational latency, and the data transfer time in runtime.
This algorithm has the feature to manage the bad-sectors of the hard-disk.
Oftentimes, what makes the difference between the performance of one operating system over the other could be the underlying implementation of its job scheduling algorithm.
This paper therefore examines, under identical conditions and parameters, the comparative performances of First Come First Serve (FCFS), Shortest Job Next (SJN) and Round Robin (RR) scheduling algorithms.As we started to have more access to hardware enhances, we could think in scaling our systems to have better performance.But this was not as easy as we first thought, because many hardware and software problems emerged.But a process needs both CPU bound and I/O bound for completion of its execution.With modernization of computers the speed of processor, hard-disk, and I/O devices increases gradually.The Conference looks for significant contributions to all major fields of the Computer Science, Engineering and Information Technology in theoretical and practical aspects.Authors are solicited to contribute to the conference by submitting articles that illustrate research results, projects, surveying works and industrial experiences that describe significant advances in the following areas, but are not limited to.The improvement of the wireless communication leads to advance research in Li Fi technology through Visible Light Communications (VLC) Technology.5th International Conference on Computer Science, Engineering and Applications (CSEA 2019) will provide an excellent international forum for sharing knowledge and results in theory, methodology and applications of Computer Science,...more5th International Conference on Computer Science, Engineering and Applications (CSEA 2019) will provide an excellent international forum for sharing knowledge and results in theory, methodology and applications of Computer Science, Engineering and Applications.more Introduction for second edition / Preface When in 1989 an anonymous reviewer commented on my short paper that “this classification should be extended to description of distributed systems,” (Yet another approach to classification of redundancy, CIM IMEKO Symp.1990, Helsinki, pp.117-124) I was really excited, because people in the research community were thinking much deeper and wider than myself (- I had just defended my Ph D).
