A linked list is like a string of pearls — each pearl holding a piece of data, and a thread that ties it to the next. In the world of programming, a linked list is a sequence of elements, where each element, called a node, holds data and a reference — or a pointer — to the next node in the chain. Unlike arrays, where elements sit next to each other in memory, linked lists are dynamic. They grow and shrink as needed. There's no wasted space, no need to predict how much data you'll need. Each node has two parts — the data, which is the information you care about, and the next, which is the pointer to the next node. Think of it like a letter that not only carries a message but also tells you where to find the next letter in the series.
