 # OS-Scheduler
 Operating systems scheduling algorithms visualization.
+it is an OS scheduler using different scheduling algorithms
+This module is responsible for generating a schedule for the current processes in the system to specify the
+CPU usage by these processes.
+implemented 4 scheduling algorithms:
+1. Non-Preemptive Highest Priority First.(HPF)
+2. First Come First Served. (FCFS)
+3. Round Robin with fixed time quantum.(RR)
+4. Preemptive Shortest Remaining Time Next.(SRTN)
+
+Library used for GUI : Tkinter  
+Library used for plots : matplotlib  
+Startup window for selecting (Input file) and (Selecting an algorithm to draw its corresponding scheduling
