Final/AP Practice Questions with
Complete and Verified Solutions
How do computer networks facilitate the sharing of information?
✔✔Computer networks allow multiple devices to connect and communicate, enabling the
sharing of resources, data, and information across different locations.
What is the significance of data compression in digital communication?
✔✔Data compression reduces the size of files or data streams, making it faster and more
efficient to transmit or store information.
How do logic gates function in computer circuits?
✔✔Logic gates perform basic logical operations (AND, OR, NOT) on one or more binary inputs
to produce a single binary output, forming the building blocks of digital circuits.
What is an API, and how is it used in software development?
✔✔An API (Application Programming Interface) is a set of protocols and tools that allows
different software applications to communicate and interact with each other.

,How does a firewall protect a computer network?
✔✔A firewall monitors and controls incoming and outgoing network traffic based on security
rules, helping to prevent unauthorized access to or from a private network.
What is the purpose of a database in managing information?
✔✔A database is used to store, organize, and manage large amounts of structured data, allowing
for efficient retrieval and manipulation of information.
How does recursion work in programming?
✔✔Recursion occurs when a function calls itself within its code, allowing for the repetition of a
process until a certain condition is met, often used for solving complex problems.
What is the impact of Moore’s Law on the evolution of computing?
✔✔Moore's Law observed that the number of transistors on a microchip doubles approximately
every two years, leading to continuous improvements in computing power and efficiency.
How do peer-to-peer networks differ from client-server networks?
✔✔In peer-to-peer networks, all devices share resources directly with each other without a
central server, while in client-server networks, clients request resources from centralized servers.
2
,What is the role of cybersecurity in protecting digital information?
✔✔Cybersecurity involves practices and technologies designed to protect systems, networks,
and data from digital attacks, unauthorized access, or damage, ensuring information integrity and
privacy.
What is the role of machine learning in artificial intelligence?
✔✔Machine learning allows artificial intelligence systems to learn from data, improve their
performance over time, and make decisions or predictions without explicit programming.
How do version control systems assist in software development?
✔✔Version control systems track and manage changes to code over time, enabling multiple
developers to collaborate, maintain code history, and revert to previous versions if needed.
What is a software framework, and how does it facilitate development?
✔✔A software framework provides a foundation with predefined structures and components,
simplifying development by offering reusable code and best practices for building applications.
How does caching improve the performance of computer systems?
3
, ✔✔Caching stores frequently accessed data in a faster, temporary storage area, reducing the time
required to retrieve data and improving overall system performance.
What is the difference between synchronous and asynchronous processing in computing?
✔✔Synchronous processing requires tasks to be completed one at a time in a specific sequence,
while asynchronous processing allows tasks to be performed concurrently, improving efficiency
and responsiveness.
How does the concept of Big Data impact data analysis and decision-making?
✔✔Big Data refers to extremely large datasets that require advanced processing techniques,
enabling more comprehensive analysis and more informed decision-making through insights
derived from vast amounts of information.
What is the purpose of a software development lifecycle (SDLC)?
✔✔The SDLC provides a structured approach to software development, including phases such
as planning, design, implementation, testing, and maintenance, ensuring systematic and efficient
project management.
