Maps, also known as dictionaries or associative arrays, are data structures that store key-value pairs. They allow efficient retrieval of values based on their corresponding keys.
Sets are collections of unique elements with no specific order. They do not store key-value pairs like maps but focus on storing distinct values.
Hash Tables: Hash tables use hash functions to map keys to indices in an array-like structure called a hash table. This allows efficient lookup and insertion operations.
Trees are hierarchical data structures consisting of nodes connected by edges. They can be used to implement various types of maps such as binary search trees and AVL trees.
