A system is running 2 CPU-bound tasks and 4 I/O-bound tasks. Each I/O bound task issues an I/O operation once every 1 millisecond of CPU. Each I/O operation takes 4 milliseconds. Assume that there is only one I/O device (so multiple I/O requests may have to queue). Assume that the context switch takes 0.2 milliseconds. Assume that each CPU-bound requires 10 milliseconds of CPU to complete and each I/O-bound task requires 2 milliseconds of CPU time. Show through a Gantt chart how the I/O and CPU are allocated and compute the average turnaround times for the CPU-bound and I/O bound tasks.

4. A multi-programmed operating system running on a single CPU assigns time slices of CPU time to the virtual machines that run the individual programs. Each virtual machine is given access to the CPU for a certain time (the time slice), during which it will continue to execute its program. The next time slice then goes to another virtual machine, and so on. Assume that each time slice is one millisecond (1/1000 of a second) long and the computer on...

A system consists of 1 CPU, 1 Disk, and 1 Network Interface. A web server running on this system consists of a process that waits for an HTTP request. Once the request is received, the process services it by fetching the requested file from disk (an I/O operation) and then by sending the file content to the client. Assume that serving a request consists of the following phases: i. Process uses the CPU for 2 msec (parse request) // CPU...

A given processor requires 1000 cycles to perform a context switch and start an interrupt handler (and the same number of cycles to switch back to the program that was running when the interrupt occurred), or 500 cycles to poll an I/O device. An I/O device attached to that processor makes 150 requests per second, each of which takes 10,000 cycles to resolve once the handler has been started. By default, the processor polls every 0.5 ms if it is...

scheduling program in C, please help
1 Objectives This programming project is to simulate a few CPU scheduling policies discussed in the class. You will write a C program to implement a simulator with different scheduling algorithms. The simulator selects a task to run from ready queue based on the scheduling algorithm. Since the project intends to simulate a CPU scheduler, so it does not require any actual process creation or execution. When a task is scheduled, the simulator will...
