Define thrashing.
Thrashing is the accident of high page traffic and low CPU utilization. It is observed that the cause of thrashing is an under-commitment of memory to programs. The cure is to enhance the memory allocation for each program. This may perhaps have to be achieved by removing some programs from the memory that is by decreasing the degree of multiprogramming.

We are faced with three major components of the page-fault service time. 1. Service the page-fault interrupts. 2. Read in the page. 3. Restart the processes.
What makes a Just-in-Time inventory system differ from a traditional inventory system?
Explain the Resource Ownership and Control Operating systems are required to handle many different types of resources. CPU , memory, and I/O devices are some of the varied sys
Explain fixed partitioning. Partitioning are the simpler techniques that don't involve virtual memory. Partitioning has been used in numerous variations in operating systems.
4. Describe priority scheduling algorithm. Consider the following set of processes. Show the order in which the algorithm will schedule these processes. Assume preemptive and non-p
What is an operating system process? How is it different from a program? Why do we need the concept of a process, rather than simply talk about programs running in memory? The e
what is the function of operation management?
