WebHashing technique is used to calculate the direct location of a data record on the disk without using index structure. In this technique, data is stored at the data blocks whose address is generated by using the hashing function. The memory location where these records are stored is known as data bucket or data blocks. WebGeneral form: h1 (k, j) = (h (k) + j) mod n. Example: Let hash table of size 5 which has function is mod 5 has already filled at positions 0, 2, 3. Now new element 10 will try to insert. 10 mod 5 = 0.
