In computer science, a data structure is a way of organizing and storing data in a computer so that it can be used efficiently. Different kinds of data structures are suited to different kinds of applications, and some are highly specialized to specific tasks. Data structures provide a means to manage large amounts of data efficiently for uses such as large databases and internet indexing services. Common examples include arrays, linked lists, stacks, queues, trees, graphs, hash tables, and heaps. The choice of data structure often depends on the problem that needs to be solved and the performance characteristics required (e.g., speed of access, memory usage).
