What techniques can be employed to minimize memory fragmentation?

To minimize memory fragmentation, several techniques can be employed. One effective technique is memory pooling. This involves allocating a large block of memory and then dividing it into smaller, fixed-size chunks. This reduces the chances of fragmentation by ensuring that similar-sized allocations are grouped together.

Another technique is to use a buddy allocator. This method splits memory into blocks of varying sizes that are powers of two. When a block is freed, it can be combined with adjacent free blocks to form larger blocks, minimizing fragmentation.

Additionally, using a garbage collector can help manage memory more efficiently. It can reclaim unused memory and compact memory spaces, which reduces fragmentation over time.

Defragmentation strategies can also be applied. These strategies involve rearranging allocated memory to create larger contiguous blocks of free memory. This is particularly useful in environments where memory allocation and deallocation happen frequently.
