Suppose the following disk request sequence (track numbers) for a disk with 200 tracks is given: 23, 89, 132, 42, 97, 35, 187 Assume that the initial position of the R/W head is on track 100. Draw the diagrams for arm movement for the seek strategies given below. Calculate the total and average number of tracks travelled and conclude which strategy performed best in the given scenario. Note: You can use pencil and paper method to draw, but you have to write your id on every pic included in the answer sheet.

a) FCFS

b) SSTF

c) SCAN

d) C-SCAN

(a) The Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, and are characterised by the fact that every number after the first two is the sum of the two preceding ones: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 114, … etc. By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two. We define Fib(0)=0,...

This project involves writing a program to calculate the terms of the following sequence of numbers: 0 1 1 3 5 11 21 43 … where each term is twice the second previous term plus the previous term. The 0th term of the sequence is 0 and the 1st term of the sequence is 1. The example below shows how to calculate the next sequence term: Current sequence: 0 1 Calculate next term: 2 * 0 + 1 = 1...
