Hashing and Hash Tables in Computer Science

Hashing and Hash Tables in Computer Science

Hi,

“Hashing” means in the terms of Computer Science that it is a transformation of some string characters into a shorter fixed length value.

Yes, “Hashing” is a “Data Structure” which is used in Computer Science.

The uses of “Hashing” are as follows:

• It is used to index database items.

• It is used to retrieve database items.

• It is also used to for finding an item faster.

• It is used for finding the original values.

• It is used for implementing an associative array.

• It is also used to compute index into array of buckets and slots.

In Computer Science, it is used as a “Hash Function”, “Hash table” and for “Collision resolution”.

In Computer Science, “Hash Table” is a data structure which is used to implement an associative array and a structure which can map the keys into values. “Hash Table” are used, when:

• Implementing an associative array.

• Compute index into array of buckets and slots.

Yes, the “Hash Table” is always based on the principles of “Hashing”.

Hope this answer will help you a lot.
