Distributed hash tables

Distributed hash tables (DHTs) are a way for a large network of computers to efficiently store and find data collaboratively. Imagine a big library where each book is assigned a unique code, and the books are spread across many shelves managed by different librarians. When you want a book, you use its code to ask the right librarian, who guides you directly to the book’s location. Similarly, DHTs use algorithms to assign data to specific nodes (computers), enabling quick and decentralized access without relying on a central server, making data sharing scalable and fault-tolerant.
