A linked list allows fast addition of elements. However, finding anything in the linked list requires sequential scanning, making it unsuitable for quick key retrieval. Thus, it's an efficient solution for logging data, creating temporary buffers, and organizing data to make sequential reads from head nodes.
Preemption is often used in different cache implementations. The cache contains data restorable from other memory sources with larger latency, stored in main memory for smart memory usage. Effective use requires storing only a small data snapshot due to main memory limitations.
