A hash table is where data storage for a key-value pair is done by generating an index using a hash function.
Open Hashing (aka Separate chaining) is simpler to implement, and more efficient for large records or sparse tables.
Closed Hashing (aka Open Addressing) is more complex but can be more efficient, especially for small data records.

Closed hashing involves storing all key-value pairs directly in the hash table, while open hashing involves using separate data structures (such as linked lists) to handle collisions. Closed hashing typically has better memory management and faster access times for non-colliding keys, while open hashing can handle a larger number of collisions without needing to resize the hash table. In database applications, closed hashing may be preferred for smaller datasets with minimal collisions, while open hashing may be more suitable for handling large volumes of data with frequent collisions.
