Ways to Avoid Internal Fragmentation

There are several ways to avoid Internal fragmentation. Some of them are mentioned below.

Variable-Sized Allocation Blocks

The system can make blocks of various sizes and use Variable-sized allocation instead of Fixed Size Allocation. Now when the system gets a request for memory allocation, it can assign the best-fit memory block to that particular process. In this way, it can be assured that a minimum amount of memory space is being wasted.

Dynamic Memory Allocation

Instead of using the basic memory allocation system to allocate memory blocks to the processes, dynamic memory allocation methods can be used. Using these methods only a specific amount of memory is assigned to a process and minimal to no memory is wasted in the process.

Internal Fragmentation is a problem that occurs due to poor memory allocation and it results in wastage of memory. When a process is loaded into the system it requests memory which is essential for its working. The operating system allocates memory to processes to work with but if the memory happens to be smaller and bigger than the process requirement the extra space goes unused. This small amount of memory unutilization is the major Internal Fragmentation appearing in the Operating System.
