Datarakenteiksi, often translated as "data structures" in English, refers to the fundamental ways of organizing and storing data in a computer so that it can be accessed and manipulated efficiently. The choice of data structure significantly impacts the performance of algorithms that operate on the data. Different data structures are suited for different types of operations and requirements.

Common examples of data structures include arrays, which store elements of the same type in contiguous memory locations, allowing for fast access to elements by their index. Linked lists, on the other hand, store elements as nodes, where each node contains data and a pointer to the next node, enabling efficient insertion and deletion of elements.

Trees are hierarchical data structures where elements are organized in a parent-child relationship, with a root node at the top. Binary search trees, a specific type of tree, allow for efficient searching, insertion, and deletion operations. Graphs represent a collection of nodes (vertices) connected by edges, used to model relationships between objects.

Stacks and queues are linear data structures that follow specific access rules. A stack operates on a Last-In, First-Out (LIFO) principle, while a queue follows a First-In, First-Out (FIFO) principle. Hash tables provide a mechanism for fast lookups using a hash function to map keys to array indices. Understanding and selecting the appropriate data structure is a crucial aspect of computer science and software development for optimizing performance and resource utilization.
