Question

What is data structure and types of data structure?

Answer 1

Data Structure is programming construct which allows us to store some information in a certain format with same data types.

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.

Answer 2

The data structure is a specific way to arranging the  data in a computer system .Linear ,tree ,graphs hash are the types of data structure

Explanation:

• The  main objective of data structure is to managing the data in a very easily and effective way .Following are the types of data structure.
• Linear: In this data structure the data is stored in a sequence manner i.e one by one array and list are comes under linear data structure .
• Tree:If we stored the data in the hierarchy manner then tree data structure is used .binary search tree is one of the example .

• Graphs: It stores the data in the non linear manner i.e not in the sequence manner .
• Hash: The hash data structure associatively stores the data there is hash function in it.
