User Guide

How to use this calculator?

1. Choose your desired Algorithm in the dropdown menu.

2. Input the Arrival Times for the processes.

   IMPORTANT: Please follow this format when typing the input:

   • Input the arrival time of the first process, follow by a space, then type the arrival time of the second process
   • E.g. 0 2 4 6 8 10

3. Input the Burst Times for the processes.

   IMPORTANT: Please follow this format when typing the input:

   • Input the burst time of the first process, follow by a space, then type the burst time of the second process
   • E.g. 8 8 8 8 8 8

4. Input the Priority for the processes (Only applicable for Non Preemptive Priority & Preemptive Priority).

   IMPORTANT: Please follow this format when typing the input:

   • Input the priority of the first process, follow by a space, then type the priority of the second process
   • E.g. 1 2 3 4 5 6

5. Input the Time Quantum for the processes (Only applicable for Round Robin).

   IMPORTANT: Please follow this format when typing the input:

   • E.g. 3

6. After completing the all the inputs required, click the Calculate button to begin the calculation

7. Output will be shown on the output panel.
