Question
Do the Memory allocation for the given case using the Buddy System
A 1024 Kbyte (Mbyte) block of memory is already allocated in the computer memory. Show the results of Buddy System memory allocation of the following sequence .There are four processes. And corresponding memory needs.
Process 1 arrived first and requested 65 K Byte memory space
Process 2 arrived after process 1 and Requested 135 K Byte memory space
Process 3 arrived after process 2 Requested 215 K Byte memory space
After process 3 allocation is done, Release P1;
Process 4 arrived and requested 45 K Byte memory space
After process 4 allocation is done Release Process 2;
Lastly, Release Process 4.
End of memory allocation
