What is a key difference between a linked list and a hash table?

A linked list employs a hash function to significantly enhance data retrieval speeds, unlike a hash table which organizes its elements in a sequential manner, relying on direct element access rather than hash$-$based indexing.

A linked list is a sequential data structure where each element is connected to the next, while a hash table stores key$-$value pairs and provides fast data retrieval using a hash function.

Both data structures are renowned for their efficiency in sorting large datasets; however, the linked list is optimized for sequential access and manipulation, whereas the hash table excels in rapid, non$-$sequential access and data retrieval operations.

Linked lists and hash tables are designed to automatically prevent the inclusion of duplicate entries, utilizing unique mechanisms to ensure the distinctiveness of each element or key within their respective structures.
