Unit 7 The Fundamentals of Computer

Text 1 Data Structure
A data structure is a data type. Its values are composed of component elements that are
related by some structure.
Since a data structure is a data type, it has a set of operations on its values. In addition, there
may be operations that act on its component elements. The operations of a structured data type
might not only act on the values of the data type, they might also act on component elements of
the data structure.
The data type’s arrays and records are native to many programming languages. By using the
pointer data type and dynamic memory allocation, many programming languages also provide the
facilities for constructing linked structures. The first two higher-level abstract data types are stacks
and queues. They are extremely important to computing.
