The chain is generated from that position as a linked list. Collision is resolved by storing multiple values together in that same index. Closed Hashing or Open Addressing tries to utilize the empty indexes in a hash table for handling collision. popular case studies in psychology

"Open addressing, or closed hashing, is a method of collision resolution in hash tables. With this method a hash collision is resolved by probing, or searching through alternative locations in the array (the probe sequence) until either the target record is found, or an unused array slot is found, which indicates that there is no such key in the table. Well-known probe sequences include: " - Open hashing techniques
