Question

Difference between fixed partition and dynamic partition in memory management

Answer 1

In fixed partitioning, the main memory is not utilized effectively. The memory assigned to each process is of the same size that can cause some processes to have more memory than they need.

In dynamic partitioning, the main memory is utilized very effectively. The memory assigned to each process is exactly what is needed for the execution of the process.

Answer 2

Partitioning means creating a section

on a drive to store data. Now partitioning

can be done in two ways

1) Fixed Partition

2) Dynamic Partition

              

Fixed Partition

In fixed partition a fixed memory is allocated

to a drive and cannot be easily expanded.

In this type of partitioning memory utilization is not done

in effective manner as we don't know how much memory we'll require

for a particular task before performing it and as a result sometimes memory is wasted in the process.

 

Dynamic Partition

Dynamic partitions can change its size when its required to.

Here the memory utilization becomes more effective as the memory is allocated

Dynamically(as per the requirement).
