Draw a timeline for each of the following scheduling algorithms. (It may be helpful to first compute a start and finish time for

12345 [234]

Answer:

See explanation below

Explanation:

Previos concepts

First Come First Serve (FCFS) "is an operating system scheduling algorithm that automatically executes queued requests and processes in order of their arrival".

Shortest job next (SJN), or the shortest job first (SJF) or shortest "is a scheduling policy that selects for execution the waiting process with the smallest execution time".

Shortest remaining time (SRF) "is a scheduling method that is a preemptive version of shortest job next scheduling'".

Round robin (RR) is an algorithm where the time parts "are assigned to each process in equal portions and in circular order, handling all processes without priority"

Solution for the problem

Assuming the dataset given on the plot attached.

Part a

For this algorithm the result would be:

Job A 0-6

Job B 6-(6+3) = 6-9

Job C 9-(9+1) = 9-10

Job D 10-(10+4) = 10-14

Part b

For this algorithm the result would be:

Job A 0-6

Job C 6-(6+1) = 6-7

Job B 7-(7+3) = 7-10

Job D 10-(10+4) = 10-14

Part c

For this algorithm the result would be:

Job A 0-1 until 14

Job B 2-(2+3) = 2-5

Job C 3-(3+2) = 3-5

Job D 9-(9+5) = 9-14

Part d

For this algorithm the result would be:

Job A 0-2 , 7-9, 12-14

Job B 2-4, 9-10

Job C 4-(4+1) = 4-5

Job D 5-7, 10-12

Write a program that prompt the user to enter the coordinate of two points (x1, y1) and (x2,y2), and displays the slope of the l

zzz [600]

Answer:

Here is code in C++.

//include headers

#include <bits/stdc++.h>

using namespace std;

//main function

int main() {

//variables to store coordinates

float x1,x2,y1,y2;

cout<<"Please Enter the coordinate of first point (x1,y1): ";

// reading coordinate of first point

cin>>x1>>y1;

cout<<"Please Enter the coordinate of second point (x2,y2): ";

// reading coordinate of second point

cin>>x2>>y2;

//calculating Slope of the line that connects these points

float m=(x2-x1)/(y2-y1);

cout<<"Slope of the line that connects these two points is : "<<m<<endl;

}

Explanation:

Declare four variables x1,x2,y1,y2 to store the coordinate of both points.

Read the coordinate of both the point from user. Calculate the slop of the

line which connects these two points with the formula m=(x2-x1)/(y2-y1).

Output:

Please Enter the coordinate of first point (x1,y1): 1 3

Please Enter the coordinate of second point (x2,y2): 5 12

Slope of the line that connects these two points is : 0.444444
