MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Collisions. Definition: A collision occurs when more than one value to be hashed by a particular hash function hash to the same slot in the table or data structure (hash table) being generated by the hash function.

Detailed explanation-2: -Collision in hashing The hash value is used to store the key in the hash table, as an index. The hash function can return the same hash value for two or more keys. When two or more keys are given the same hash value, it is called a collision. To handle this collision, we use collision resolution techniques.

Detailed explanation-3: -Explanation: In a hash table, if sevaral elements are computing for the same bucket then there will be a clash among elements. This condition is called Collision. The Collision is reduced by adding elements to a linked list and head address of linked list is placed in hash table.

Detailed explanation-4: -Open 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.
