A linked list is made up of nodes, each of which has a data element and a pointer (or reference) to the node after it in the list. Each node in dynamic partitioning represents a memory block that can be assigned to a process. The linked list initially reflects the whole memory block that is accessible. In this article, we will explore the Linked List for Dynamic Partitioning, what Dynamic Partitioning is in Memory Management, and also the implementation of Linked List in Dynamic Partitioning. Dynamic Partitioning in Memory Management Computer systems employ the memory management approach known as "dynamic ... Read More
