Hashmap is a data structure that stores key-value pairs and allows for quick retrieval of values based on keys.

• Hashmap uses a hash function to map keys to indices in an array.

• Collisions can occur when multiple keys hash to the same index, which can be resolved using techniques like chaining or open addressing.
