What is a binary number system?

• The binary number system is a base-2 numeral system that uses only two digits, 0 and 1, to represent numbers

• The binary number system is a base-10 numeral system that uses digits 0 through 9 to represent numbers

• The binary number system is a numbering system that uses letters and symbols instead of numbers for computation

• The binary number system is a mathematical system that alternates between three different digits: 0, 1, and 2

What is an Algorithm?

• An algorithm is a programming language used to write software applications

• An algorithm is a random sequence of numbers used to encrypt data

• An algorithm is a type of computer hardware that processes data

• An algorithm is a step-by-step set of instructions designed to perform a specific task or solve a problem

Decomposition is a component of computational thinking. What is decomposition?

• Decomposition is the process of breaking down a complex problem into smaller, more manageable parts to make it easier to solve

• Decomposition is the process of converting binary numbers into decimal numbers

• Decomposition is a technique used to randomly generate code for solving problems

• Decomposition is the process of merging multiple solutions into one large problem

Abstraction is a component of computational thinking. What is abstraction?

• Abstraction is the process of randomly generating numbers to solve complex problems

• Abstraction is the process of filtering out unnecessary details to focus on the essential aspects of a problem

• Abstraction is the process of converting high-level programming languages into binary code

• Abstraction is a method of physically removing data from a computer system

What is iteration in coding?

• Iteration is the process of converting programming languages into machine code

• Iteration is the process of repeating a set of instructions in a loop until a certain condition is met

• Iteration is the process of writing code without using any loops or repetitions

• Iteration is a technique used to permanently store data in a computer’s memory

What is data integrity?

• Data integrity refers to the accuracy, consistency, and reliability of data

• Data integrity is the process of encrypting data to prevent unauthorised access

• Data integrity is the ability of a system to store unlimited amounts of data without errors

• Data integrity is a method of compressing data to save storage space

What is a check digit?

• A check digit is a randomly generated number assigned to every dataset for identification

• A check digit is a type of encryption method used to protect sensitive data

• A check digit is a special character used to separate numbers in a database

• A check digit is an extra digit added to a number to detect errors in data entry or transmission

What is encryption?

• Encryption is a method of compressing data to reduce file size

• Encryption is the process of permanently deleting files from a computer system

•  Encryption is the process by which a readable message is converted to an unreadable form to prevent unauthorised access

• Encryption is a technique used to improve the speed of a computer processor
