Considerations for Algorithms and Programs

How does a check digit function in data validation?

• It is used to verify the integrity of identification numbers by adding a single digit to the original number.
• It is used to add a letter to the original number
• It is used to decrease the length of the original number
• It is used to encrypt the identification numbers

Which of these IS a benefit of implementing error handling into a program?

• Decreased reliability

• Decreased execution time

• Improved user experience

• The program uses less computer resources

Which of these is an example of data that would benefit from a limit check?

• Personal identification number (PIN) for an ATM card
• Email address

• Mother's maiden name
• Profit

What is the purpose of data validation?

• To make the data less secure
• To slow down the system
• To make the data more confusing and inconsistent
• To ensure that the data entered into a system is accurate, consistent, and secure.

What is a JSON file?

• A file used for storing video content
• A file format that stores data in a structured and organized manner

• A file format for audio data
• A type of image file

In programming, what is the difference between an array and a list?

• Arrays and lists are the same thing
• The main difference is that arrays have a fixed size, while lists can dynamically change in size.
• Arrays can only store numbers, while lists can store any type of data
• Arrays are used in Python, while lists are used in Java

What is meant by a dynamic data structure in programming?

• A data structure that can only be accessed sequentially
• A data structure that can only store integers
• A data structure that can grow or shrink in size during execution
• A data structure that remains fixed in size

What is meant by data verification?

• Collecting new data
• Ensuring that data is in a suitable format for processing

• Deleting all data
• Checking and confirming the accuracy and quality of data
