AP Computer Science Principles 100% Correct What is a `list comprehension` in Python, and how is it used? A `list comprehension` in Python is a concise way to create lists using a single line of code. It allows for the generation of lists by applying an expression to each element in an iterable, optionally filtering elements based on a condition. How does a `recursive` function work, and what is its purpose? A `recursive` function is a function that calls itself to solve a pro...

AP Computer Science Principles Vocabulary 100% Correct What is algorithm in computer science? An algorithm is a step-by-step procedure or formula for solving a problem or performing a task. It is a set of instructions designed to be followed in a specific order to achieve a desired outcome. Define abstraction and its role in programming. Abstraction is the process of simplifying complex systems by focusing on the essential features and ignoring the details. In programming, it h...

AP Computer Science Principles Exam with Verified Solutions What are algorithms, and why are they important in computer science? Algorithms are step-by-step procedures or formulas for solving problems. They are important because they provide a systematic way to solve computational problems and are foundational to programming and problem-solving in computer science. How does abstraction help in programming? Abstraction helps in programming by allowing programmers to manage comp...

AP Computer Science Principles Latest Version 100% Verified What is an algorithm? An algorithm is a step-by-step set of instructions designed to perform a specific task or solve a problem. What is the purpose of a loop in programming? A loop allows a set of instructions to be repeated multiple times until a certain condition is met. What does the term "abstraction" mean in computer science? Abstraction refers to simplifying complex systems by focusing on the main ideas while ...

AP Computer Science Principles Exam Prep with Verified Answers What is a "nested loop" and how is it used? A nested loop is a loop within another loop, used to iterate over multidimensional data structures or perform complex repetitive tasks. What does "code modularity" involve and why is it beneficial? Code modularity involves breaking code into smaller, reusable modules or functions, improving readability, maintainability, and testability. How does "recursion" work and wh...

AP Computer Science Principles Questions and Answers 100% Pass What is the difference between a syntax error and a logic error in programming? A syntax error occurs when the code violates the rules of the programming language, preventing it from compiling or running. A logic error occurs when the code runs but produces incorrect results due to a flaw in its logic. How does iteration differ from recursion in solving problems? Iteration involves repeating a block of code using loops, wh...

AP Computer Science Principles 100% Verified What is a "boolean" in programming? A boolean is a data type that represents true or false values. What is the purpose of a "constructor" in a class? A constructor initializes an object's state when it is created. What is a "list" in programming? A list is a data structure that holds an ordered collection of items, which can be of different types. What does "iteration" mean in the context of loops? Iteration refers to the ...

AP Computer Science Principles Final/AP Practice Questions with Complete and Verified Solutions How do computer networks facilitate the sharing of information? Computer networks allow multiple devices to connect and communicate, enabling the sharing of resources, data, and information across different locations. What is the significance of data compression in digital communication? Data compression reduces the size of files or data streams, making it faster and more efficient to tran...

AP Computer Science Principles College Board Questions with Verified Solutions What is a flowchart, and how is it used in designing algorithms? A flowchart is a graphical representation of an algorithm’s steps and decision points, used to visually map out the process flow and logic. How does a stack data structure operate, and what are its primary use cases? A stack operates on a Last In, First Out (LIFO) principle, where the last element added is the first one to be removed. It is ...
