Various Types of Data Structure You Should Know

Data structures are a specialized way to organize and store information on computers in a way that we can carry out operations on the stored data with greater efficiency. They offer a broad and varied range of applications across all areas that comprise Computer Science and Software Engineering. They are utilized in nearly every software program that has been built. Additionally, types of data structure in the realm of the fundamentals that comprise Computer Science and Software Engineering. This is an important subject when it comes to Software Engineering interview questions. Therefore, as developers, we need to know a lot regarding data structure.

In this blog, I’ll briefly explain 8 types of data structure that every programmer should know.

What is Data structure?

Data structures are a way to organize and store information in a computer so that it can be utilizing to execute actions on it.

In the end, it’s not appropriate for analysis or the operations. Unstructured data is an extremely common issue. The estimate is that 80percent of all data in the world is not structuring.

Many organizations collect information and keep it in an unorganized fashion that does not work in making it easy to access.

There are various kinds (forms) of structure for data, each can be useful for specific tasks, but not all.

Therefore, it is the programmers responsibility to figure out what types of data structure is appropriate to efficiently analyze the data so that it can be utilize to solve problems or accomplish the objective.

The data structures form the basic principles of computer science, and are utilize in the majority of software systems.

The most common types of data structure


The term “array” refers to a form of data with a fixed size that can contain items of the same kind. It could comprise an integer array or floating-point numbers, an array of strings as well as an array of arrays (such as 2-dimensional arrays). They are indexable, which means that they can be accessing at random.

Linked Lists

The linked list can be described as a structure made up of of items that are in linear order, which are linked to one another. Therefore, you must access the data in a sequential manner and random access isn’t feasible. Linked lists offer an easy but flexible method of representing dynamic sets.


A stack is an LIFO (Last In First Out -the part that is which is finally placed in the first place can be accessed the beginning) structure that can be frequently found in a variety of programming languages. This type of structure is known”stack “stack” because it resembles an actual stack, a pile of plates.


A queue is an FIFO (First In, First Out) component that is first placed is accessible at first) structure that can be frequently found in a variety of programming languages. The structure is referring to as “queue” because it resembles an actual queue — people who are waiting in a line.

Hash Tables

Hash Table is a Hash Table is a type of data structure that can store value that has keys that are associated with each. It also supports search efficiently when you know which key is that is associating to the value. Therefore, it is extremely efficient when inserting and searching regardless what size the file.

Direct Addressing employs the one-to-one mapping of the keys and the values when storing in tables. There is however an issue with this method when there are a large quantity of key/value pair. The table could be enormous with so many records , and could be difficult or impossible to store in the amount of memory available in a normal computer. To get around this problem, we make use of hash tables.


The term “tree” refers to a structure that organizes data by hierarchy and linked. This structure differs from a linked listing, where when a linked list is created items are connecting in a linear manner.

Different kinds of tree types have been creating over the last few decades to fit specific applications and satisfy certain requirements. Examples include the binary search tree, B tree, treap red-black tree tree as well as AVL and the n-ary tree.


A heap is a specific instance in a tree of binary in which the nodes of the parent contrasting with their children by their respective values and are arranging in a specific way.


It is another types of data structure. A graph is made up of an infinite number of vertices, or nodes and an array of edges that connect these vertices.

The order of graphs is the amount of vertices within the graph. The size of graphs is determining by the number of edges within the graph.

Two nodes are considering to be adjacent if they are linking to one another by exactly the same edges.

Wrap Up

Every data structure has many uses and applications. A basic understanding of the types of data structure is the initial step to becoming a proficient programmer. To gain a thorough knowledge of the data structure, register in the data structure and algorithms course. C++ course and learn the most efficient programming language and data structures to tackle programming problems. You’ll be able to fully master analysing and implementing algorithms and also be able to determine the most effective algorithm for different circumstances.
