Lecture 2: Module I: Introduction to Data & file structures. Lecture 3: Linear data Structures – Linked list and applications. Lecture 4: Stack and Queue. Lecture. Data structure usually refers to an organization for data in main memory. File structure: an organization for data on peripheral storage, such as a disk drive or. File Structures. ▫ Data structure for data stored on disk. ▫ Implementation of queries requires. • File structures. • Algorithms for operators. • Sorting, selection ( σ).

These linear structures are termed as arrays. But the ID that is assigned to a student would normally be considered as a single item. These are data structures used for space partitioning or binary space partitioning. From Wikipedia, the free encyclopedia. Arrays Queues Stacks Linked lists Nonlinear Data Structure This structure is mostly used for representing data that contains a hierarchical relationship among various elements. Categories of Data Structure The data structure can be subdivided into major types:

Let us take an example where the name of the student may be divided into three sub-items namely: But the ID that is assigned to a student would normally be considered as a single item. What is Data Structure?

In computer terms, a data structure is a Specific way to store and organize data in a computer's memory so that these data can be used efficiently later. Data may be arranged in many different ways such as the logical or mathematical model for a particular organization of data is termed as a data structure.

The variety of a specific data model depends on the two factors - Firstly, it must be loaded enough in structure to reflect the actual relationships of the data with the real world object. Secondly, the formation should be simple enough so that anyone can efficiently process the data each time it is necessary.

Categories of Data Structure The data structure can be subdivided into major types: There are two techniques of representing such linear structure within memory. The first way is to provide the linear relationships among all the elements represented using linear memory location.

These linear structures are termed as arrays.

The second technique is to provide a linear relationship among all the elements represented by using the concept of pointers or links. These linear structures are termed as linked lists.
