type
What does “debugging” mean in software development?
✔✔ Finding and fixing errors or bugs in the code
What is the purpose of a loop in programming?
✔✔ To repeat a block of code multiple times based on a condition
What is the main advantage of using functions in code?
✔✔ To break down complex problems into reusable and manageable parts
1
,What is an algorithm?
✔✔ A step-by-step procedure for solving a problem or performing a task
What is a variable in computer programming?
✔✔ A storage location that holds a value which can change during program execution
What is object-oriented programming?
✔✔ A programming paradigm based on the concept of objects that contain both data and
methods
What is the role of RAM in a computer system?
✔✔ It temporarily stores data and programs that are currently in use by the CPU
What does IP address stand for?
