WebOpen Hashing or Chaining method creates an external chain of values that has the same index. 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.
