CPU BURST:cpu burst is that when cpu wait for input process and after completion input burst cpu do process on that job...
cpu burst is like a car and input output burst is like a pedestrian..bec cpu speed is much faster than input output burst...we can not reduce the speed of cpu burst but we can increase the input out put speed...

CPU Burst :- "The amount of time the process uses the processor before it is no longer ready".
Types Of CPU burst :-
1. Long burst : ("Process is CPU bound")
2. Short burst : ("Process I/O bound")

I/O Burst :- "Input/Output burst is that after completion the input burst CPU do process on that job".
Explanation :- CPU burst is like a car and input Input burst is like a pedestrian , because CPU speed is much faster than Input Output burst , we can not reduce the speed of CPU burst but we can increase the Input Output speed.

CPU burst is when the process is being executed in the CPU. I/O burst is when the CPU is waiting for I/O for further execution. After I/O burst, the process goes into the ready queue for the next CPU burst.

Preemptive SJF: This scheduling algo processes the job with minimum CPU burst time. if any other job arrives having lesser CPU BT. It will preempt the current one and provide CPU to the shortest one. CPU BT: the time taken by a process for execution by CPU and IO BT: time taken for IO event.
