What is hash table and hash function?
In computing, a hash table (hash map) is a data structure that implements an associative array abstract data type, a structure that can map keys to values. A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value can be found.

A hash table is typically an array of linked lists. When you want to insert a key/value pair, you first need to use the hash function to map the key to an index in the hash table. Given a key, the hash function can suggest an index where the value can be found or stored: index = f (key, array_size)
What does chaining mean in a hash table?
As mentioned earlier, chaining means that each key/value pair in the hash table, the value is a linked list of data rather than a single cell. For example, imagine that the key 152 holds the value “John Smith”. If the value “Sandra Dee” is added to the same key, “Sandra Dee” is added as another element to key 152, just after “John Smith”.
