Introduction to Data Structures and AlgorithmsData Structure is a way of collecting and organising data in such a way that we can perform operations on these data in an effective way. Data Structures is about rendering data elements in terms of some relationship, for better organization and storage. For example, we have some data which has, player's name 'Virat' and age 26. Here 'Virat' is of String data type and 26 is of integer data type.We can organize this data as a record like Player record, which will have both player's name and age in it. Now we can collect and store player's records in a file or database as a data structure.For example: 'Dhoni' 30, 'Gambhir' 31, 'Sehwag' 33If you are aware of Object Oriented programming concepts, then a class also does the same thing, it collects different type of data under one single entity. The only difference being, data structures provides for techniques to access and manipulate data efficiently.In simple language, Data Structures are structures programmed to store ordered data, so that various operations can be performed on it easily.
It represents the knowledge of data to be organized in memory. It should be designed and implemented in such a way that it reduces the complexity and increases the efficiency.Basic types of Data StructuresAs we have discussed above, anything that can store data can be called as a data structure, hence Integer, Float, Boolean, Char etc, all are data structures.

They are known as Primitive Data Structures.Then we also have some complex Data Structures, which are used to store large and connected data. Some example of Abstract Data Structure are:. Linked List. Tree. Graph.
Stack, Queue etc.All these data structures allow us to perform different operations on data. We select these data structures based on which type of operation is required. We will look into these data structures in more details in our later lessons.
