Introduction


Do you want to gain knowledge about data structure and the various types of data structures? If yes, congratulations you are in the right place. In this article, we will be dealing with the same.

What is Linear Data Structure?


Data structures are the in-depth concept of Software Development. The linear data structure is usually associated with computer science. Users use this structure for organizing, managing & stockpiling data format for systematic access and revision.

The computer; we use for several purposes; works on computer programs. These programs are directly dependent on the huge volume of data for performance. Here comes the need to arrange the data. And this arrangement of data in an organized system is defined as a data structure.

Today, linear data structures are utilized to organize bulky data while categorizing/indexing services. Precisely speaking, data structures are routes to well-organized and logical algorithms. The primary purpose of forming a linear data structure is to minimize the space and reduce the time complicacy of different tasks.

Now that you are well aware of the definition of linear data structure lets dive deep into the various types of linear data structure.

List of the linear Data Structure examples


1. Array


The array is one of the types of linear data structures that accumulate elements at memory locations. All the elements stores are contiguous in type. You can understand an array as a structure that stores invariable objects in a proper sequence.

The plan or scheme by which an array is formed is to store numerous data of the same type altogether. The 1st thing to be decided here is the size of the array; only then can one store the data. In an array, one can easily access or modify a particular element stored as per their locations.
You can understand the array with the help of an example: Suppose there are 100 patients in a hospital, then the size of the array has to be mentioned as 100. The age of all the students can then be stored in the created array. Here you need not create distinct variables for the ages of every patient. A simple traversal of the array will be enough to access its elements.

2. Stack


A stack is a data structure where the elements are arranged in such a manner that it follows up the LIFO principle. LIFO means last-in-first-out. Hence, in a stack, the last element stored will be removed first. Stack is often federated with 2 types of operations i.e. push and pop. Push  adding of an element & POP  removing the last element. You can understand the stack by means of an example: Suppose there is a heap of coins and the last coin kept on the pile is removed first.

3. Queue


While talking about the types of linear data structures, one has to include Queue Data Structure. Unlike a stack that works in the LIFO (last-in-first-out) manner, queue data structure works in the FIFO (first-in-first-out) principle. Here, in the queue data structure, the first element stored in the queue has to be initially removed. You can understand queue data structure with the help of an example: Suppose a queue of people in the bus stand; then the first person in the queue will enter the bus first followed by others.

4. Linked list


The linked list is another classification of data structure. Here, the user stores separate objects in a proper sequence. Every single object stored in the data structure will have the data and a reference to the succeeding object. A linked list has a head  the 1st element of the linked list. It also has a null  the final node of the linked list.
A linked list differs from the other 3 types of data structures mentioned above. The primary differences can be illustrated based on memory allocation, internal structure, and the operations executed on the linked list.

In an array, one can easily get on to any particular element; but in a linked list its much more tough & slow. It is because the indexing process in a linked list begins from the head and navigates through the entire structure until a particular element is reached. However, a linked list has an advantage over other types of data structures; i.e. adding or deleting elements can be done at the beginning very swiftly.

Final Takeaway


All in all, we can say that enormous data size is a prerequisite for the proper use of data structures in computer programs. You can opt for any of the 4 types of data structures while working on a computer program. Always remember, organized data enhances the performance of tasks over the elements.
