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

hiding the underlying details.




How is a variable used in programming?


✔✔A variable is a storage location in memory that holds data, which can be changed or

manipulated during program execution.




1

,What is the significance of "conditional statements" in programming?


✔✔Conditional statements allow a program to make decisions and execute different code paths

based on whether certain conditions are true or false.




What is the function of an IDE (Integrated Development Environment)?


✔✔An IDE is a software application that provides comprehensive tools for coding, debugging,

and testing programs.




What is the difference between a compiler and an interpreter?


✔✔A compiler translates an entire program into machine code before execution, while an

interpreter translates and executes code line by line.




What is a function or method in programming?


✔✔A function or method is a block of code designed to perform a specific task, which can be

called upon when needed in a program.




What is the purpose of data types in programming?


✔✔Data types define the kind of data a variable can hold, such as integers, floats, or strings,

ensuring proper handling and manipulation of data.

2

,What does "syntax" refer to in computer programming?


✔✔Syntax refers to the set of rules that define the correct structure and format of code in a

programming language.




What is a "parameter" in the context of functions?


✔✔A parameter is a variable used in a function to receive input values when the function is

called.




What is the role of "debugging" in the software development process?


✔✔Debugging is the process of identifying, isolating, and fixing bugs or errors in a program to

ensure it runs correctly.




What does "iteration" mean in programming?


✔✔Iteration refers to the repetition of a process or set of instructions in a loop until a certain

condition is met.




What is a "binary number system"?




3

, ✔✔The binary number system is a base-2 numerical system that uses only two digits, 0 and 1, to

represent all possible numbers.




What is the significance of an "array" in programming?


✔✔An array is a data structure that stores a collection of elements, typically of the same data

type, in a contiguous block of memory.




What does "encapsulation" mean in object-oriented programming?


✔✔Encapsulation is the concept of bundling data and the methods that operate on that data

within a single unit or class, restricting direct access to some of the object’s components.




What is the purpose of "inheritance" in object-oriented programming?


✔✔Inheritance allows a new class to inherit properties and behaviors (methods) from an existing

class, promoting code reuse and organization.




What is "polymorphism" in the context of programming?


✔✔Polymorphism is the ability of different objects to respond in their own way to the same

method or function call, allowing for flexible and reusable code.
