Question # 3Suppose your system has a memory of size 100 MB using contiguous memory allocations and there are 4 fixed size partitions. Partition one of size 50, partition 2 of size 200, partition 3 of size 100 and partition 4 of size 150 Consider First 5 letters of your name. The ASCII code of the letters is the size of process and the alphabet is the name of process. The processes appear in alphabetical order. Q): How many processes will be loaded in the memory at a time? For contiguous memory allocation show the algorithms used to allocate memory partitions to each process and state which algorithm will work best and why? Also state the amount of internal and external fragmentation for the processes and partitions after allocation
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.…
Course: Operating Systems Given below is the pseudocode to synchronize processes P1, P2, P3, P4, P5, and P6 byusing three semaphores X, Y and Z that are initialized as follow: X=0, Y=0, Z= –2. TheOperating System can schedule the processes which are ready to execute in any order.List down at least 5 possible orders of execution in which the processes can run.
An operating system uses the Banker's algorithm for deadlock avoidance when managing the allocation of three resource types X, Ý, and Z to three processes PO, P1, and P2. The table given below presents the current system state. There are 3 instances of type X, 2 instances of type Y and 2 instances of type Z still available. The system is currently in a safe state. Answer the following questions! Allocation Max X Y z X Y PO 0 1 8 4 3 (a) If PO requests 2 instances of Z during the P1 3 2 current state, can it be granted? Explain! (b) If P1 requests 2 instances of X during the P2 2 1 1 3 3 3 current state, can it be granted? Explain! CO
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…

The control signal Ep or iEnableoutput allows the program counter to decrement its value. True False The control signal Ep or iEnableoutput sends the content of the program counter to the W bus. True False A tri-state buffer is needed for all data going to the W bus. True False In using 'assign' statement in Verilog, the left hand side must always be a register. True False In declaring a register in Verilog, the following format must be followed: reg [LSB:MSB] identifier; True False
Please refer to this textbook: “A. Silberschatz, P. B. Galvin and G. Gagne, “Operating System Principles,”7th Edition, John Wiley & Sons Inc., 2006.” And answer the following questions: Question:The Ricart& Argwala mutual exclusion algorithm: (a) Does not depend on time stamps in messages while Lamport's does. (b) Cannot handle the case where two or more processes request the same resource at the same time. (c) Does not require a process to send messages to the entire group while Lamport's does. (d) Requires fewer messages than Lamport's algorithm.
