Data Structure Applied Areas on ComputerDefinition of Data Structure Applied Areas on Computer - A data structure is a way of organizing data that not only store data Items, but also establish relationship among each other. Deep knowledge regarding the relationship between data items allows designing of efficient algorithms for the manipulation of data items. They are designed to organize data to suit specific purpose such that it can be accessed and operate in appropriate manner. The efficiency to store, access and process data in excellent manner gave rise to the concept of data structure. Alternatively data structure is a way of organising data in computer so that it can be used efficiently.



What are the Types of Data Structure?


There are generally two types of data structure. They are built in data Structure and User defined Data structure.


Built In Data Structure – Integer, float, Pointer, Char etc.


User Defined data Structure – Graphs, Tree, Array, Stack, Queue etc.


In which areas Data Structure is applied?


The data Structure is extensively used in number of field or areas some of them are –



  1. Artificial Intelligence

  2. Operating System

  3. Simulation

  4. Graphics

  5. Statistical analysis

  6. Compiler Design

  7. Database Management System

  8. Numerical Analysis



Popular Examples of Data Structure



  1. Array
    - Array is a data structure used to store homogeneous data values at contiguous locations. The Size of the array must be provided before storing the data. Alternatively, an array is systematic order of same objects which are arranged in rows and columns. Example – Let we look an example for declaring an array –



Int lookarray (50); - This is an integer array named lookarray where upto 50 elements can be stored.



  1. Linked List – This is the data structure which store data not in contiguous location and uses pointers for linking or locating the data. It has dynamic size and easy to insert or delete the data. There are various types of functions that linked list create like delete, insert, update etc.

  2. Stack
    - Stack is a linear data structure which play a particular order in which the operations are performed. The order may be LIFO (Last in First Out) or FILO (First in Last Out). There are three basic operations performed in stack. They are Push, Pop and Isempty.

  3. Push: Adds an item into the stack. If the stack is full, then declared to be an Overflow condition.

  4. Pop: Removes an item from the stack. The items are popped in the reversed order in which they are pushed. If the stack is empty, then declared to be an Underflow condition. Peek or Top: Returns top element of stack.

  5. isEmpty: Returns true if stack is empty, else false.


  6. Queue - A queue or FIFO (first in, first out) is a collection of elements, with two main operations:


    1. Enqueuer - The process of adding an element to the collection.(The element should added from the rear side)

    2. Dequeuer - The process of removing the first element that was added. (The element is removed from the front side).



  7. Hashing – Hashing is used to search data according to related keyed used therein. Like storing employee name keyed using phone no. What next to do are –

  8. Insert a phone number and corresponding name.

  9. Search a phone number and fetch the name.

  10. Delete a phone number and related name.



So there are many other data structure used in computer organisation to use data efficiently. So this is a short description regarding Data Structure Applied Areas on Computer.

When Task Scheduler gets Infected by Malware

When Task Scheduler gets Infected by Malware

When Task Scheduler gets Infected by Malware - We are familiar with malware attacks on Computer. The hackers infect one or more files and thereby attaining full control on the System. There are millions of victims who had loosen either data or dollars in this respect. In this article we see a System file which is infected by these hackers at first stage. The System file infected by malware at first stage is Task Scheduler Engine (Taskeng.exe). The Task Scheduler Engine is a system file located in C:\Windows\System32 folder. This location is the default location for Taskeng.exe.



The Task Scheduler Engine is responsible for keeping track of tasks set to run at a time predefined by the user of the PC. As said earlier, the original location of this scheduler is C:\Windows\System32 folder. But it is suspicious if the location of scheduler gets change. If it is found in some other folder then it must be infectious. As a result, you constantly get a…

How to Project Android Phone Screen on Windows PC


Project Android Phone Screen on Windows PC - Four out of Five of us have Smartphones in our Pocket. We spend lots of time on Smartphone utilities like Facebook, Twitter, WhatsApp, YouTube and other interesting Apps. These Smartphones are tremendously used due to Android Operating System installed in it. Android OS is one the successful mobile based OS running in the market.

On the Other side, Microsoft is emphasizing on features to ease Android user's connectivity with it. Microsoft has done lots of improvement for mobile utilities to the Windows 10 version 1809. With this upgradation, we can easily project Android phone screen on Windows PC. The extensive use of such features is seen on Digital Smart TVs Today. The introduction of Wi-Fi feature makes more reliable and user friendly.

So, if you are boredom with 5-6-inch Android Screen and want to mirror it on Computer screen, then read the full article to know the process, how to proj…

Fix Windows could not find a driver for your network adapter error

Fix Windows could not find a driver for your network adapter error


A Computer run smoothly with the coordination of Software & Hardware. In the absence of any one it will not run at all. Software being the Master utilizes each hardware attached to the System. And each hardware is operated with the help of Device Drivers installed in it. Operating System (OS) uses these device drivers to control & utilize each hardware when needed. Each hardware connected to the system must have their own Device Driver installed. A device driver is a program to initiate a hardware when required by Operating System.




Suppose, you want your PC to connect to the Network, it can only be possible when your PC has network related Device Driver. These Device Drivers are easily downloaded from Manufacturer Websites. In this article we focus on Network related problem. Suppose, your PC not obtaining Network connectivity. And each time you are getting an error message saying "Windows could not find a d…
