Programming L1

What is the purpose of programming in computing?

• To create documents

• To define the binary representation of data

• To discuss its role in computing

• To play video games

Answer explanation

The purpose of programming in computing is to discuss its role in computing, not to create documents, define binary representation of data, or play video games.

Imagine Abigail is working on her computer science project. She needs to understand how her computer stores the project files. What is she trying to understand?

• The way computers process human languages

• The representation of data and programs

• The difference between machine and high-level languages

• The structure of a simple program

Answer explanation

Binary representation in computers refers to the representation of data and programs in the form of 0s and 1s, which is the fundamental language understood by computers.

During a computer science class, Michael was asked to identify which of the following is NOT a type of programming language used in real-world computing.

• Machine language

• High-level language

• Assembly language

• Quantum language

Answer explanation

The correct choice is 'Quantum language' as it is NOT a type of programming language, unlike Machine language, High-level language, and Assembly language.

Scarlett is working on a web project and needs to choose a programming language that is usually interpreted for client-side scripting. Which language should she choose?

• C++

• Java

• JavaScript

• C#

Answer explanation

JavaScript is usually interpreted, unlike C++, Java, and C# which are usually compiled languages.

Why is sequencing important in programming a recipe app for Ava?

• It defines the binary representation of the app

• It ensures the app is written in high-level language

• It explains the role of programming in app development

• It describes the structure and explains why sequencing is important

Answer explanation

Sequencing in a simple program describes the structure and explains why sequencing is important for the program to function correctly.

During a project meeting, Anika suggests using pseudocode to accomplish what task?

• To strategize their next multiplayer video game session

• To outline the program's flow for their upcoming design document

• To evaluate the pros and cons of different programming languages

• To categorize different types of programming languages for their report

Answer explanation

Pseudocode is primarily used to show program flow using a design document, helping to plan and visualize the logic of a program before actual coding.

Imagine Aiden is working on a project that involves automating tasks in a computer. What is the role of programming in Aiden's project?

• To provide entertainment

• To define the structure of the program Aiden is working on

• To control the behavior of the computer in Aiden's project

• To create graphical user interfaces for Aiden's project

Answer explanation

Programming is essential in computing as it controls the behavior of a computer, allowing users to perform various tasks and operations.

Charlotte is working on a project that requires a high-level programming language for easier maintenance and readability. Which of the following languages should she use?

• Assembly

• Machine language

• Python

• Binary code

Answer explanation

Python is an example of a high-level programming language because it is designed to be easily readable and writable by humans, unlike low-level languages like Assembly or Machine language.

Liam is working on a project that requires fast execution and is considering using a compiled language. Jackson argues that for their project's flexibility during development, an interpreted language might be better. What is the primary difference between the languages they are discussing?

• Compiled languages are used for web development, while interpreted languages are used for system programming.

• Compiled languages are translated into machine code before execution, while interpreted languages are translated during execution.

• Interpreted languages can only be used on Windows operating systems, while compiled languages can be used on any platform.

• Compiled languages are older and not used anymore, while interpreted languages are modern and widely used.

Answer explanation

Compiled languages are translated into machine code before execution, while interpreted languages are translated during execution.

Why is sequencing important when programming a recipe app for Aria and Samuel?

• It determines the color scheme of the app's user interface.

• It defines the order in which recipe steps are executed by the user.

• It ensures that the app uses the least amount of memory on Abigail's phone.

• It allows the app to be written in multiple programming languages.

Answer explanation

Sequencing is important in a simple program as it defines the order in which statements are executed, ensuring the program runs correctly.
