Hashes are implemented using hash functions to map data to unique fixed-size values, typically used for fast data retrieval.
Hash functions are used to generate a unique hash value for each input data
Hash tables use these hash values as keys to store and retrieve data efficiently
Common hash functions include MD5, SHA-1, and SHA-256
Hash collisions can occur when different inputs produce the same hash value
Singleton design pattern ensures a class has only one instance and provides a global point of access to it.
