1Textbookcs4-q1

What is Artificial Intelligence (AI)? Explain with an example. Mention the applications of AI.

Ans.AI (Artificial Intelligence) is the ability of a computer or machine to think, learn, and make decisions like humans, using data and patterns instead of emotions. Example: a voice assistant like Siri understands spoken commands and gives useful replies by processing language data. Applications of AI: Healthcare (diagnosing diseases from X-rays/MRIs), Education (adapting lessons to student needs), Transportation (self-driving cars, route optimization), Retail & E-commerce (product recommendations), Smart Assistants, Security (facial recognition), Robotics, and Natural Language Processing.
2Textbookcs4-q2

What is Machine Learning (ML)? Differentiate between supervised and unsupervised learning with suitable examples. Mention the applications of ML.

Ans.ML (Machine Learning) is a part of AI where computers learn from data and improve themselves without being directly told what to do. Supervised Learning uses labeled data (data with correct answers) - e.g., an image recognition system trained on pictures already labeled 'cat' or 'dog' can later identify a new picture correctly. Unsupervised Learning uses unlabeled data - e.g., a machine given many unlabeled photos automatically groups similar-looking nature photos together and face photos together. Applications of ML: recommendation systems (YouTube, Netflix), search engines (Google autocomplete), healthcare (disease detection), finance (fraud detection), self-driving cars, and voice recognition.
3Textbookcs4-q3

How does Artificial Intelligence play a crucial role in the field of robotics? Explain.

Ans.AI helps robots think, learn from experience, and make decisions instead of only following fixed instructions. AI allows robots to sense their surroundings using sensors, find patterns, and act according to the situation, making them flexible and useful in cleaning, medicine, factories, and transport. For example, a cleaning robot uses sensors to detect a wall and AI helps it decide to turn and continue cleaning instead of stopping. Without AI, the robot would simply stop at the obstacle.
4Textbookcs4-q4

What is Integrated AI? Mention any two uses of integrated AI tools in office work with examples.

Two uses in office work: (i) Google Docs uses Smart Compose and Grammar Check to make writing and editing faster and more accurate. (ii) Microsoft Office 365's Excel uses Data Analysis to automatically find patterns and create charts from office data.
5Textbookcs4-q5

What is the Internet of Things (IoT)? How does IoT help in the development of smart cities and smart homes?

Ans.The Internet of Things (IoT) is a technology where everyday physical objects like machines, home appliances, vehicles, lights, and security systems are connected to the internet, allowing them to collect and share data and work automatically without human help. In smart cities, IoT is used in traffic control systems, smart streetlights, and public safety alarms to help cities run better.

6Textbookcs4-q6

How does cloud computing make computing tasks reliable? Mention the features of cloud computing.

Ans.Cloud computing makes computing tasks reliable because data and applications are stored on remote servers with automatic backup, so users don't lose their work even if their own device fails, and they can access their files anytime from any device with an internet connection. Features of cloud computing: On-Demand Service, Broad Network Access, Resource Pooling, Rapid Elasticity, Measured Service, and Virtualization.
7Textbookcs4-q7

What is cloud computing? Explain the cloud computing models.

Ans.Cloud Computing is a technology that allows people to store, manage, and access data and programs over the internet instead of using their own computer's hard drive, providing services like storage, software, and processing power through online servers. The cloud computing models are: (i) SaaS (Software as a Service) - ready-made software accessed via the internet, e.g., Google Docs, Gmail. (ii) PaaS (Platform as a Service) - a platform for developers to build and deploy apps, e.g., Google App Engine, Firebase.

9Textbookcs4-q9

How does e-governance make services reliable and effective for citizens? Illustrate with examples.

Ans.e-Governance provides government services online, making them faster, more transparent, and accessible without visiting government offices physically. For example, citizens can check SEE exam results online, fill passport application forms, or pay electricity and water bills through apps, saving time and reducing corruption through transparent digital records. This makes services more reliable because they are available anytime and processed faster than manual paperwork.
10Textbookcs4-q10

How does e-education change the traditional education system? Why is it reliable for the teaching-learning process? Illustrate with examples.

Ans.e-Education changes the traditional education system by allowing students and teachers to connect online for classes, share study materials, and take exams without being physically present in school - for example, attending online classes on Zoom or watching recorded lessons on YouTube. It is reliable for teaching-learning because it offers flexibility (learning anytime, anywhere), access to a wide range of digital resources, and personalized learning at each student's own pace, though it still depends on a stable internet connection.
11Textbookcs4-q11

Mention the merits and demerits of cloud computing.

13Textbookcs4-q13

What are ethical issues in AI? Explain the ethical issues in AI.

Ans.Ethical issues in AI are the fairness, safety, and privacy concerns that arise from how AI is built and used. The three main ethical issues are: (i) Bias - AI may treat people unfairly if trained on unbalanced data, e.g., favoring one gender in job screening. (ii) Privacy - AI systems handle personal data like photos and voice recordings, which can leak if not protected. (iii) Security - AI systems used in hospitals, banks, and factories can be hacked and misused, causing serious harm like stolen money or dangerous control of machines.
