B-tree vs. Binary tree — What's the Difference?
By Tayyaba Rehman — Published on January 3, 2024
B-trees are balanced tree data structures optimized for systems that read and write large blocks of data. Binary trees are hierarchical structures with each node having at most two children.

Key Differences
B-trees are multi-way trees designed for disk storage where nodes can have more than two children. This structure reduces the number of disk accesses necessary for operations. Binary trees, on the other hand, are simpler tree structures where each node has at most two children, typically referred to as left and right child.
In a B-tree, each node can hold multiple keys and can have multiple children, leading to a balanced and shallow structure ideal for storage systems. The number of keys and children in each node depends on the order of the B-tree. In contrast, a Binary tree follows a strict structure where each node can have zero, one, or two children, leading to a potentially deeper tree structure.
B-trees are widely used in databases and file systems due to their efficiency in handling large data sets and maintaining sorted data. They are optimized for systems that read and write large blocks of data. Binary trees are fundamental in computer science, used in various applications like expression parsing, searching, and sorting algorithms.
The balance of a B-tree ensures that all leaf nodes are at the same depth, providing efficient access and search operations. Binary trees can become unbalanced depending on the insertion and deletion order, which can affect their performance in search operations.
B-trees dynamically adjust their height and balance by splitting and merging nodes, which makes them adaptable to various data operations. Binary trees require additional mechanisms like rotation in AVL trees or red-black trees to maintain balance.
