2. In programming languages a data type is an attribute of a datum which tells the computer and the programmer something about the kind of datum it is. This involves setting constraints on the datum, such as what values it can take and what operations may be performed upon it. Common data types may include: integers, floating-point numbers, and alphanumeric strings.

3. In computer science, a data structure is a way of storing data in a computer so that it can be used efficiently. Often a carefully chosen data structure will allow the most efficient algorithm to be used. The choice of the data structure often begins from the choice of an abstract data type. A well-designed data structure allows a variety of critical operations to be performed, using as few resources, both execution time and memory space, as possible. Data structures are implemented by a programming language as data types and the references and operations they provide.
