Assume that a memory module contains three holes of 10MB each. A sequence of 14 requests for 1MB each will be processed (See the diagram below). For each of the memory allocation methods listed below, draw a diagram representing how memory is allocated and determine the sizes of the remaining holes after all 14 requests have been satisfied. First fit Next fit C. Best fit d. a. b. Worst fit Hint - For the Next fit, the following allocation starts with the hole following the previous allocation 10 Mb 10 Mb 10 Mb
2. a) Your colleague has invented a new scheduling algorithm using the multilevel queue approach. This list of processes showing CPU burst times is below. There are three queues used in the application. The processes all start on the first queue and receive upto 10ms of burst time. Once the process has received the 10ms on the first queue, if the process still requires burst time it is passed to the second queue where it receives upto 20ms. Once the process has received the 20ms on the second queue, if the process still requires burst time it is passed to the third queue where it receives CPU time until it is completed. The operating system will only start allocating CPU time to processes on the second queue when queue 1 is empty. The operating system will only start allocating CPU time to processes on the third queue when queue 2 is empty. Process Number P1 P2 P3 P4 Burst time (ms) 21 8 35 50 i) Does this algorithm give higher priority to any queue over the others and any processes…
There are many parameters that could be used to describe disk performance; among them are: number of bits per track disk capacity (in bits) number of disk surfaces rotational speed rotational latency transfer rate tracks per surface sectors per track blocks per track sectors per block seek time speed of disk arm block-read time number of blocks Some of these parameters are independent, and others are (approximately) linearly related. That is, doubling one doubles the other. Decide which of these parameters are linearly related. Then, select from the list below, the relationship that is true, to within a close approximation. Note: none of the statements may be true exactly, but one will always be much closer to the truth than the other three. Also note: you should assume all dimensions and parameters of the disk are unchanged except for the ones mentioned. a) If you divide tracks into half as many blocks, then you double the read time for a block.…
The following terminology is used when referring to this memory hierarchy: hit- The requested data resides in a given level of memory. Mass- The requested data is not found in the given level of memory. Hit rate - The percentage of memory accesses found in a given level of memory. Mass rate- The percentage of memory accesses not found in a given level of memory. Hit time - The time required to access the requested information in a given level of memory. Miss penalty - The required to process a miss, which includes replacing a block in an upper level of memory, plus the additional time to deliver the requested data to the processor. Why does the text make this claim: The time to process a miss is typically significantly larger than the time to process a hit.
A single-CPU system has four processes, P1, P2, P3 and P4 in the ready queue. The execution times and I/O needs for these processes are given below. All times are in ms. (hint: when a process starts an IO operation, it is removed from the ready queue and put back at the end of the queue only when it completes its IO). Process P1: Arrives at 0ms, needs 23ms of CPU time. Performs I/O for 5ms after 10ms of its execution time, then another 5ms after 20ms of its execution time. Process P2: Arrives at 3ms, needs 12ms of CPU time. Performs I/O for 10ms after 5ms of its execution time. Process P3: Arrives at 1ms, needs 15ms of CPU time. Performs I/O for 1ms after 7ms of its execution time. Process P4: Arrives at 2ms, needs 8ms of CPU time. Performs I/O for 5ms after 4ms of its execution time. We assume that the CPU is idle if no one of these four processes is using it. Using Round Robin scheduling algorithm with a Time Quantum of 4ms and ignoring the context switch time, determine: a) The…
Problem DescriptionThe Tower of Hanoi ProblemTower of Hanoi is a mathematical game consisting of three pegs (P1, P2 and P3) and a stack of disks of different diameters. Disks can slide onto any peg. The game starts with all disks stacked on P1 and ends at the point where all disks stacked on P3. The game player is required to move all disks from P1 to P3 using P2 as a buffer. Three rules must be followed when playing the game(1) Only one disk may be moved at a time.(2) Each move involves taking a disk on the top of a peg and place it on the top of another peg. (3) A disk of a larger diameter should never be placed on top of a disk of a smaller diameter. The diagrams below demonstrate the starting state and goal state of the game with 5 disks.Starting state Goal stateP1 P2 P3 P1 P2 P32RequirementsIn this assignment, students are required to solve the Tower of Hanoi (with five disks) using state space search algorithms implemented in Python.Two state space search algorithms: (1) a blind…
