Comp $431$ Final Project midnight : $15/06/2024$

$1)$ The project simulates the memory management technique, "Multiple Partitions $-$Variable Regions", known in IBM machines as MVT $($Multiprogramming with Variable number of Tasks$).$

$2)$ Write a program to simulates the behavior of MVT memory management. technique.

$3)$ Consider a memory of size $2$ GB$=2048$ MB$,512$ MB is allocated for the OS$.$

$4)$ Initially, the ready queue and the job queue are represented by the text files ready.txt and job.txt$,$ each line in the files contains:

Process$-$no process$-$size time$-$in$-$memory

Read the given text file ready.txt and allocates all the process to memory in the same

order given in the file.

Whenever a job finishes execution, a new job is brought from the job queue on FCFS

with skip.

$5)$ I suggest to use a table data structure to represent PCB that contains, process$-$id$,$ size, time in memory, base & limit registers.

$6)$ When the number of holes in memory $>3,$ a compaction$($defrag$)$ must be done, that is$,$ reallocates the jobs again in memory creating one big hole at high memory.

$7)$ You should maintain a lists of allocated regions and free holes.

$$ What is the output of the project?

$$ Use graphics to show a diagram of memory contents in details.

$$ The contents of the ready & job queues in every step.

$$ Which job finishes execution, which job brought into memory to replace it $($ready queue$).$

$$ A diagram showing memory allocated partitions and free holes when the job finishes execution.

$$ A diagram showing all memory partitions before and after compaction.
