Final answer:
In Dynamic Partitioning of memory management, the placement algorithm that selects the smallest memory block large enough for the request is called Best Fit.
Step-by-step explanation:
In the Dynamic Partitioning technique of memory management, the placement algorithm that chooses the block that is closest in size to the request is called Best Fit.
The goal of this algorithm is to reduce the size of the unused memory fragments that are left, which are commonly known as internal fragmentation. When a process requests memory, the best fit algorithm searches through all the free memory blocks and chooses the smallest block that is large enough to accommodate the requested size.
The dynamic partitioning technique can employ various placement algorithms, each with different strategies for selecting free memory for processes.
Besides best fit, other common algorithms include first fit, where the first block that is large enough is chosen, and worst fit, which selects the largest block available, often leading to significant internal fragmentation. The best fit approach attempts to find a balance between efficiently using memory and minimizing waste.
