Data Structure

Representing information is fundamental to computer science. The primary purpose of most computer programs is not to perform calculations, but to store and retrieve information - usually as fast as possible. We must organize that information in a way that allows us to find the answers in time to satisfy our needs.
In computer science, a data structure is a particular way of organizing data in a computer so that it can be used efficiently. Different kinds of data structure algorithms are used to different kinds of applications, and some are highly specialized to specific tasks. For example, databases use B-tree indexes for small percentages of data retrieval and compilers and databases use dynamic hash tables as look up tables. Even an integer or floating point number stored on the computer can be viewed as a simple data structure.
