Understanding Data Structures

The video tutorial introduces computational thinking and focuses on data structures, specifically trees and graphs. It explains the importance of data structures in efficiently storing and accessing data. The tutorial covers linear and nonlinear data structures, with a detailed look at tree structures, their hierarchical nature, and applications. It also explores graph structures, their components, and real-world applications. The video concludes with a comparison of trees and graphs and suggests a creative activity to reinforce understanding.

What is the primary purpose of data structures in computing?

• To make data look organized

• To store data in a way that is efficient for processing

• To increase the size of data

• To confuse programmers

Which of the following is an example of a static linear data structure?

• Stack

• List

• Array

• Queue

In a tree data structure, what is the term for a node with no children?

• Root

• Trunk

• Branch

• Leaf

Which of the following is NOT a real-world application of tree data structures?

• Educational syllabi

• Decision making processes

• Social media networks

• File system organization

What is a common analogy used to describe tree data structures?

• A family tree

• A social network

• A city map

• A shopping list

What is a key characteristic of graph data structures?

• They are always linear

• They cannot represent complex relationships

• They consist of vertices and edges

• They have a single root node

Which of the following is a common use of graph data structures?

• Organizing a company's hierarchy

• Mapping transportation routes

• Storing a list of items

• Creating a family tree

Which of the following best describes a vertex in a graph?

• A root node

• A cycle in the graph

• A line connecting two points

• A point where two edges meet

How does a tree differ from a general graph?

• A tree can have cycles

• A tree is a type of graph without cycles

• A tree has multiple roots

• A tree is not a graph

Which statement is true about all trees?

• Trees have multiple root nodes

• All graphs are trees

• All trees are graphs

• Trees always contain cycles
