Verification, validation and test data

Which type of data validation checks if the data entered is of the correct type (e.g., numeric, text)?

• Range check

• Length check

• Type check

• Pattern check

What is a "range check" in data validation?

• It checks if the data is within a specified range of values

• It checks if the data is a valid email address

• It checks if the data is a whole number

• It checks if the data is a valid date format

Which of the following is an example of a format check in data validation?

• Ensuring a phone number contains only numbers and dashes

• Verifying that a number is within a specific range

• Checking that a password is at least 8 characters long

• Ensuring that an email address is unique

What is the purpose of data validation in a computer program?

• To convert data into a different format

• To store data in a secure location

• To generate random data for testing

• To ensure that data entered meets certain criteria or constraints

What is the primary purpose of data verification in a computer system?

• To encrypt sensitive data

• To organize data in a database

• To check the accuracy and correctness of data before it is processed

• To generate random data for testing

What is the main difference between data validation and data verification?

• Data validation encrypts data, while data verification organizes it.

• Data validation generates random data, while data verification checks for completeness.

• Data validation and data verification are synonymous terms.

• Data validation checks the format of data, while data verification checks its accuracy.

Which of the following is an example of a data verification process?

• Generating a random set of numbers for testing purposes

• Double-checking a bank account number before processing a transaction

• Converting text data to numeric format

• Rearranging data in a spreadsheet

Why is data verification important in computer systems?

• It helps ensure that data is stored securely

• It reduces the risk of processing incorrect or inaccurate data

• It speeds up the processing of data

• It is not necessary for effective data management

What type of test data is used to ensure that a program works with typical, everyday input?

• Normal data

• Abnormal data

• Extreme data

• Boundary data

Which type of test data is used to test how a program handles input that is outside the expected range or limits?

• Normal data

• Abnormal data

• Extreme data

• Boundary data
