FCFS



SSTF



SCAN



CSCAN

The x-axis and y-axis shows the time taken and locations in the disk respectively. Yellow, green, blue and red curves denote FCFS, SRTF, SCAN and CSCAN respectively.

Please note that the curves may overlap resulting in the colours being superimposed on each other especially when the request sequence is small. To see invisible curves hover the mouse over various points of the visible curves
