Data Structures and Algorithms Quiz

What is a data structure?

• A programming language

• A method to organize and store data efficiently

• A type of database

• A computer hardware component

Which of the following is NOT a data structure?

• Array

• Stack

• CPU

• Linked List

What is the primary purpose of a database?

• To write code

• To store and organize data for retrieval and updates

• To execute programs

• To create data structures

Where is data in a database stored?

• RAM

• Registers

• Hard disk, CDs, and DVDs

• Cache memory

What differentiates data structures from databases?

• Databases store related data permanently, while data structures manage data for algorithmic operations

• Data structures store data permanently like databases

• Databases do not use data structures internally

• Data structures and databases are the same

Which of the following data structures operates in a Last In, First Out (LIFO) manner?

• Queue

• Stack

• Graph

• Array

What is the main purpose of an algorithm?

• To store data permanently

• To solve a problem step by step

• To execute hardware instructions

• To create databases

Which factor determines the efficiency of an algorithm?

• The programming language used

• The size of the program code

• The time and space complexity

• The type of computer hardware

What is the worst time complexity among these algorithms?

• O(1)

• O(Log n)

• O(n³)

• O(n!)

The running time of an algorithm depends on:

• The speed of the CPU

• The number of inputs processed

• The programming language used

• The size of the screen
