Key words * Blocked state- a process that cannot execute until some events occur, such as the completion of an I/O operation. * Exit state- a process that has been released from the pool of executable process by the OS, either because it halted or because aborted from some reason. * New state- a process that has just been created but has not yet been admitted to the pool of executable process by the OS. * Ready state- a process that is prepared to execute when given the

higher rate than experienced nurses (Patterson, 2009) I do believe things can be done to change these issues. I feel it is important, though it is not always practical to involve the new staff in the scheduling process and, as the article states, include as a “Team scheduling” process, rather than a “self scheduling”. This may make more people feel involved, and although it may not solve all of the issues, such as weekends or holidays, it may be a small change that will improve job satisfaction

Operating system concepts(Seventh edition) 2008.3 solutions to the exercises Chapter 1 1.1 In a multiprogramming and time-sharing environment, several users share the system simultaneously. This situation can result in various security problems. a. What are two such problems? b. Can we ensure the same degree of security in a time-shared machine as in a dedicated machine? Explain your answer. Answer: a. Stealing or copying one’s programs or data; using system resources (CPU, memory, disk space

INTRODUCTION The common statement we use to define a process is that a process is a program in execution. In more detailed version we can say that a process is a sequence of interdependent and linked procedures which at every stage consumes one or more than one resources to convert inputs into outputs. These outputs then serves as an input for the next stage until a known goal or an end result is achieved. A process in execution needs resources like processing resources

PROCESS MANAGEMENT b.1) Multitasking is when there is two or more programs running at the same time and both are working. The processor will allocate some resources to each program. The processor switching back and forth between tasks so quickly that might look like the processor doing the two things at once. It is also means performing more than one process on a single CPU. Multiple processes are queued and wait for their turn to be executed on CPU, but it appears as if they are running in parallel
