  There are many techniques to store and retrieve data and the performance of these techniques is depending upon the type and structure of data. According to given question hashing is the fastest ways to store and retrieve data.
  Almost all searching technique, the search time is dependent on the number of items and many key comparisons are involved. Hashing is a technique where search time is independent of the number of items. This technique uses hash function to generate an address from a key. We can write hash function as follows
  h(k)=a;
  Where h is hash function, k is the key, a is the hash value of the key.
