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

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

What is text compression?
Text compression is a method of converting text into binary code for storage
Text compression is the process of encrypting text to protect it from unauthorized access
Text compression is a technique used to duplicate text data to improve redundancy
Text compression is the process of reducing the size of a text file by encoding data more efficiently while maintaining its meaning
What is casting in Python coding?
Casting is the process of creating a copy of a variable for backup purposes
Casting is the process of converting one data type into another, such as converting a string to an integer
Casting is the process of combining multiple variables into a single variable
Casting is a method of hiding errors in the code to make it run smoothly
What is a variable in coding?
A variable is a type of function that performs calculations in a program
A variable is a storage location in memory that holds a value which can be changed during the program’s execution
A variable is a specific type of error that occurs when the program cannot access data
A variable is a fixed value in the program that cannot be changed once it is set
What is input in coding?
Input is the data or information that is provided to a program for processing by the user
Input is a type of error that occurs when the program cannot access data from the user
Input is a process of storing data permanently in a database
Input is the result produced by a program after it has processed data
What is output in coding?
Output is the process of entering data into a program for it to process
Output is the process of storing data temporarily in a program's memory
Output is a type of error that occurs when the program cannot process data correctly
Output is the result produced by a program after processing input
