Question

Describe data structure and describe about its need and types

Answer 1

♦ DATA STRUCTURE: A data structure is a logical method of representing data in memory using the simple and complex data types provided by the language.

Data structures can be classified into the following two types:
• Simple data structure
• Compound data structure

*. Simple data structure: These data structures are generally built from fundamental data types i.e. , int, float, char etc.
Its two types are:
(1). Array
(2). Structure

*. Compound data structures: These data structures are formed by using simple data structures and are more complex.
Its two types are:
(1). Linear data structures: These are single level data structures, having their elements in a sequence.
Example:
(a). Stack
(b). Queue
(c). Linked list

(2). Non-linear data structures: These are multilevel data structures.
Example:
(a). Tree
(b).Graph.

Answer 2

The scheme of organizing related information is known as ‘data structure’. 

The types of data structure are:
Lists: A group of similar items with connectivity to the previous or/and next data items.
Arrays: A set of homogeneous values
Records: A set of fields, where each field consists of data belongs to one data type.
Trees: A data structure where the data is organized in a hierarchical structure. This type of data structure follows the sorted order of insertion, deletion and modification of data items.
Tables: Data is persisted in the form of rows and columns. These are similar to records, where the result or manipulation of data is reflected for the whole table.
