Which of the following is an example of abstraction in computer science?
Abstraction in computer science involves hiding the complex details of a process or task while providing a simple interface. Functions are a key example of abstraction because they allow a programmer to use a pre-defined operation without needing to understand its inner workings.
What is the purpose of an algorithm in computer science?
An algorithm is a clear, step-by-step set of instructions used to solve a problem or perform a task. Algorithms are fundamental to problem-solving in computer science and guide the design of programs and systems.
Which of the following best describes "decomposition" in computational thinking?
Decomposition is the process of breaking down a complex problem into simpler, more manageable subproblems. This allows programmers to focus on one part of the problem at a time, making it easier to solve overall.
A software developer is building a new app that requires the ability to perform calculations. Which of the following is the most effective way to design the app’s calculation feature?
Using an already-defined function to perform calculations is a better approach because it promotes code reuse, improves efficiency, and reduces the risk of errors. It also allows the developer to focus on other aspects of the app’s functionality.
Which of the following is an example of pattern recognition in computational thinking?
Pattern recognition involves identifying trends or regularities within data, which helps in creating solutions based on these identified patterns. Recognizing patterns is an important step in problem-solving because it simplifies the process and often leads to more efficient solutions.
