What is a collision in a hash table?

Answer: Collision is defined as the event that takes place when the clash appear due to the information persisting the same hash value get in contact. This mechanism occurring in the hash table is called collision and is dependent on the type of application.

Collision becomes difficult to be avoided in a large set of the hash table as the data set is difficult to be found while in small hash table it is still detectable but cannot be avoided completely.
