GCSE Computer Science Paper 2: Topic 3

What is the primary goal of defensive design in programming?

• To prevent the program from crashing due to user errors

• To ensure the program is user-friendly

• To make the program aesthetically pleasing

• To make the program run faster

What does iterative testing primarily focus on?

• Testing the complete software at the end

• Testing the documentation

• Testing each module during its development

• Only testing the user interface

What is the main purpose of terminal testing in software development?

• To ensure all parts of the program work together

• To test the final product for performance

• To test the program's installation process

• To check individual modules

Which testing method involves checking the entire program at the end of the development process?

• Iterative testing

• Validation testing

• Terminal testing

• Module testing

What type of error is caused by not following the syntax rules of the programming language?

• Index error

• Validation error

• Runtime error

• Logical error

What is the purpose of validation in defensive programming?

• To enhance the graphical user interface

• To reduce the cost of software development

• To improve program efficiency

• To ensure user input meets certain criteria

What is the role of authentication in defensive design?

• To improve the resolution of images in the program

• To increase the program's marketability

• To make the program install faster

• To verify the identity of the user

Which type of testing data is on the edge of being allowed?

• Normal data

• Boundary data

• Invalid data

• Erroneous data

What is the difference between invalid and erroneous data?

• Invalid data is correct type but wrong, erroneous is wrong type

• Invalid data is the wrong type, erroneous is not

• Invalid data is always numerical, erroneous is textual

• There is no difference; both terms mean the same

Why is it important to test software with erroneous data?

• To evaluate the user manual's clarity

• To assess the speed of the program

• To ensure the program handles unexpected data types gracefully

• To check the color scheme of the interface
