What is hashing and its uses ? Hashing is the process of taking any digital value for example a password and applying some kind of mathematical operation to it which is known as a hashing algorithm or hashing function and obtaining the resulting changed value called a hash or hash value. Hashing is a function used to map data to a fixed-length value. Businesses use hashing in authentication systems and to also validate different types of data such as files Hashing can help prevent data breaches and protect stored info. What are hash tables ? A hash table which is also known as a hash map is a data structure that maps keys to values. It is one part of a technique which is called hashing, the other of which is called a hash function. A hash function is essentially a algorithm responsible for creating indexes where values can be found or stored and with this data structure it is beneficial because all data has a structure which follows a key value pair system where data can be easil...
