Question 2
The operating system maintains a linked list where each node represents each
partition. Every node has three fields:
A field that stores a flag bit which shows whether the partition is a hole or a process.
A field that stores the starting location of the partition.
O
A field that stores the size of the partition.
Draw the linked list that represent the memory allocation shown here.
Redraw the linked list after process 2 terminates.
Redraw the linked list when process 4 is loaded.
Assume process 4 requires 300 memory address and allocation
uses first fit algorithm.
