Understand the basic concepts of Data Structures

Semantically data can exists in either of the two forms – atomic or structured. In most of the programming problems data to be read, processed and written are often related to each other. Data items are related in a variety of different ways. Whereas the basic data types such as integers, characters etc. can be directly created and manipulated in a programming language, the responsibility of creating the structured type data items remains with the programmers themselves. Accordingly, programming languages provide mechanism create and manipulate structured data items.
