About Data Structures Question Bank With Answers

The data structure, in computer science, is defined as a data organisation, management, and storage format that allows efficient access and modification. In simpler words, data structures can be termed as the collection of data values, the relationship prevailing among them and the functions and operations that are possible to be applied to the data.

They are the basis of Abstract Data Types (ADT). The ADT is used to define the logical form of data type, whereas the data structure describes the physical form of a data type. Data structures are of different types and are suited for different kind of applications, and some are also highly specialised for specific tasks only. Data structures provide a medium to manage a large amount of data efficiently for uses such as databases and internet indexing services.

Data structure generally depends on the capability of the computer in fetching and storing data inside the memory of computer, which is to be specified by a pointer. The implementation of data structure generally requires to write a set of procedures that would create and manipulate the instances of a particular structure. It is not possible to analyse the efficiency of data structure separately from the operations.

All these concepts and basics can be learned from the data structures question bank with answers PDF as it includes questions that have the ability to give a detailed overview of a data structure without any doubt.

Frequently Asked Questions on Data Structure Question Bank With Answers

Question 1.
What are the advantages of data structures?

Answer:
Some of the advantages of data structures are

  • It allows information storage on hard disks.
  • It provides means of management for large datasets, for example, databases or internet indexing services.
  • It is required for designing efficient algorithms.
  • It allows security to storage by providing safe storage of information on a computer.
  • It helps in data usage and processing on a software system.
  • Processing of data can be much easier with the data structure.
  • In the data structure, a person can access the data anytime at any place using the internet, which is a beneficial aspect of data structuring.

Question 2.
What are the disadvantages of data structure?

Answer:
Some of the important disadvantages of the data structure are:-

  • Applications which are using data structure for operations requires a highly qualified professional resource that can manage the operations related to the data structure easily. Acquiring this professional resource is very difficult.
  • If the data structure used to maintain and control the application is more significant, then it must require a lot of workforces. Increase in labour cost will make data structure operations expensive.
  • Designing a data structure is very difficult as it involves a complex algorithm. It will require a lot of time and testing to prove that it is ready to be used in a organisation.

Question 3.
What is a binary tree in data structure?

Answer:
Binary tree in computer science can be defined as a tree data structure in which each node consists of at most two children. These two children are referred to as the left child and the right child. The binary tree sometimes is also interpreted as an undirected rather than as a directed graph. In these cases, the binary tree is an ordered and rooted tree. Some authors also use a rooted binary tree in spite of the binary tree to emphasise on this particular fact.

Question 4.
What do you understand by a linked list?

Answer:
Linked list is defined as a collection in a linear way of data elements whose orders are not mentioned by their physical placement in the memory. Instead, in this case, each element points to the next element. This is a type of data structure that consists of a collection of nodes which together can be represented as a sequence.
