WebSeparate Chaining is the collision resolution technique that is implemented using linked list. When two or more elements are hash to the same location, these elements are represented into a singly-linked list like a chain. Since this method uses extra memory to resolve the collision, therefore, it is also known as open hashing. WebOpen Addressing, which is also known as closed hashing is a technique of collision resolution in hash tables. The main idea of open addressing is to keep all the data in the same table to achieve it, we search for alternative slots in the hash table until it is found.
