OSP 2 is written within the Java programming language and scholars application their OSP 2 tasks in Java besides. for that reason as necessities for utilizing OSP 2 , scholars are anticipated to have reliable Java programming abilities; be well-versed in object-oriented programming innovations similar to periods, gadgets, tools, and inheritance; to have taken an undergraduate machine technology direction in info constructions; and to have operating wisdom of a Java programming atmosphere, i. e. , javac, java, textual content modifying, and so on. OSP 2 is the successor to the unique OSP software program, which used to be published in 1990 and programmed in C. OSP 2 involves a couple of modules, every one of which plays a uncomplicated working platforms provider, resembling gadget scheduling, cpu scheduling, interrupt dealing with, dossier administration, reminiscence administration, approach administration, source administration, and interprocess conversation. initiatives should be equipped in any wanted order as a way to growth in a fashion in keeping with the lecture fabric.
