Understanding Trees and Binary Trees in Computer Science

What is a tree in computer science?

• A data structure consisting of nodes and pointers

• A hardware component

• A type of function

• A programming language

What is the root node of a tree?

• The node at the very bottom of the tree

• A node that contains pointers to other trees

• The node with no child nodes

• The topmost node in a tree data structure

What are leaf nodes?

• Nodes at the very bottom of the tree

• Nodes that can store data

• The topmost node of the tree

• Nodes with at least two child nodes

What is a binary tree?

• A tree where each node can only have zero, one, or two child nodes

• A tree structure used exclusively for binary operations

• A tree with nodes that have data and two pointers

• A tree where each node can have up to three child nodes

How can binary trees be represented in memory?

• As a series of interconnected networks

• Through a single, linear array

• With dictionaries, as shown in Python

• Using linked lists

What is a common use of binary trees?

• Generating random numbers

• For creating visual graphics

• Database applications for efficient searching and sorting

• Storing simple lists of data

What is a subtree?

• A smaller tree structure within a larger binary tree

• The process of removing nodes from a tree

• A set of nodes and edges from any single node down through all of its descendants

• A tree that grows in a virtual environment

What is NOT a typical use for trees in computer science?

• Calculating arithmetic expressions

• Wireless networking and router tables

• Storing and managing file and folder structures

• Implementations of the A* pathfinding algorithm

How are nodes in a binary tree connected?

• Through a central server

• By using a stack

• With pointers

• Via email

What operation is NOT mentioned as a binary tree operation?

• Adding

• Multiplying

• Traversing

• Deleting
