Questions and Answers 100% Pass
What is the difference between a syntax error and a logic error in programming?
✔✔A syntax error occurs when the code violates the rules of the programming language,
preventing it from compiling or running. A logic error occurs when the code runs but produces
incorrect results due to a flaw in its logic.
How does iteration differ from recursion in solving problems?
✔✔Iteration involves repeating a block of code using loops, while recursion solves problems by
having a function call itself with modified parameters until a base condition is met.
What is the significance of Big-O notation in evaluating algorithms?
✔✔Big-O notation describes the efficiency of an algorithm in terms of time and space
complexity, helping to predict how the algorithm performs as input size grows.
Why is modularity important in software development?
✔✔Modularity allows a program to be divided into smaller, reusable components, making the
code easier to manage, debug, and extend.
1
,What is the role of an API (Application Programming Interface) in software development?
✔✔An API provides a set of protocols and tools that allow different software applications to
communicate with each other, enabling the integration of external services or libraries.
How does a sorting algorithm organize data?
✔✔A sorting algorithm rearranges the elements in a list or array according to a specific order,
such as ascending or descending.
What is the purpose of a database in computer systems?
✔✔A database stores, manages, and retrieves structured data efficiently, enabling applications to
handle large volumes of information.
How do Boolean operators influence decision-making in programming?
✔✔Boolean operators (AND, OR, NOT) combine or negate conditions, influencing the flow of a
program by determining which code blocks execute based on true or false evaluations.
What is the difference between lossless and lossy data compression?
2
,✔✔Lossless compression reduces file size without losing any data, allowing the original data to
be perfectly reconstructed. Lossy compression reduces file size by discarding some data, which
can result in a loss of quality.
How do computer simulations help in solving real-world problems?
✔✔Computer simulations model complex systems and scenarios, allowing researchers and
developers to analyze potential outcomes, test hypotheses, and make informed decisions without
real-world risks.
What are the ethical implications of artificial intelligence in decision-making?
✔✔Ethical implications include concerns about bias, privacy, accountability, and the impact of
AI decisions on individuals and society, requiring careful consideration and regulation.
How does cloud computing benefit businesses and developers?
✔✔Cloud computing offers scalable resources, cost efficiency, and flexibility, allowing
businesses and developers to access computing power and storage over the internet without
maintaining physical infrastructure.
What is the role of debugging in the software development process?
3
, ✔✔Debugging involves identifying, isolating, and fixing errors or bugs in code, ensuring that the
software runs correctly and efficiently.
How does parallel computing differ from traditional computing?
✔✔Parallel computing divides tasks into smaller sub-tasks that run simultaneously on multiple
processors, improving performance and reducing processing time compared to traditional,
sequential computing.
What is the significance of version control systems in collaborative programming?
✔✔Version control systems track changes to code, allowing multiple developers to collaborate,
manage versions, and revert to previous states if needed, improving project organization and
reducing conflicts.
What is an example of an undecidable problem in computer science?
✔✔The Halting Problem is an example of an undecidable problem, where it is impossible to
create a program that can determine whether any arbitrary program will halt or run indefinitely.
How do firewalls contribute to network security?
