 Related Questions A real time process is a process that must respond to the events within a certain time period. A real time operating system is an operating system that can run real time processes successfully Latest Answer : can u name some of the real time o.s ... A real time operating system has well defined fixed time constraints. Process must be done within the defined constraints or the system will fail. An example is the operating system for a flight control Describe different job scheduling in operating systems? Scheduling is the activity of the deciding when process will receive the resources they request.FCFS: --- FCSFS stands for First Come First Served. In FCFS the job that has been waiting the longest is Paging is solution to external fragmentation problem which is to permit the logical address space of a process to be noncontiguous, thus allowing a process to be allocating physical memory wherever the Switching the CPU to another process requires saving the state of the old process and loading the saved state for the new process. This task is known as a context switch.Context-switch time is pure overhead, Waiting state Latest Answer : processor:busy stateprocess:waiting state ... ->Selects from among the processes in memory that are ready to execute, and allocates the CPU to one of them.->CPU scheduling decisions may take place when a process:1.Switches from running to waiting Latest Answer : Disk schedulers in current operating systems are generally work-conserving, i.e., they schedule a request as soon as the previous request has finished. Such schedulers often require multiple outstanding requests from each process to meet system-level ... ->Dispatcher module gives control of the CPU to the process selected by the short-term scheduler; this involves:Switching contextSwitching to user modeJumping to the proper location in the user program Latest Answer : The short-term scheduler (also known as the dispatcher) decides which of the ready, in memory processes are to be executed (allocated a CPU) next, following a clock interrupt, an IO interrupt, an operating system call or another form of signal. Thus ... Throughput – number of processes that complete their execution per time unitTurnaround time – amount of time to execute a particular processWaiting time – amount of time a process has Latest Answer : Throughput:Total amount of work done in a unit of time.Waiting Time:The amount of time that is taken by a process in ready queue.Turn Around Time:The sum total of waiting time & execution time is known as the turnaround time.Response Time:The time ... Multi programming: Multiprogramming is the technique of running several programs at a time using timesharing.It allows a computer to do several things at the same time. Multiprogramming creates logical Latest Answer : yeah its precise...but can u throw more light on the differences between multiprogramming and multi tasking??thanks in advance ...
