DSA Linked Lists in Memory
This lesson is part of DSA · All levels
Summary
This topic explains how linked lists are mapped to the physical memory of a computer. Unlike arrays with adjacent elements, node linked lists are spread out and linked by addresses stored on the pointer. The null pointer marks the end of the list, and each insertion only changes the neighboring pointer without touching the other elements.
Key points
- Node is not adjacent; address is stored on field pointer
- Pointer null marks the last node
- Inserting nodes only requires updating the neighboring pointer
- The allocation is spread out so that the memory can be fragmented.
