Questions with Answers and Explanations (Class 7)

1. What is Artificial Intelligence (AI)?

Answer:
Artificial Intelligence (AI) is the ability of a computer or machine to think, learn, and make decisions like humans.

Explanation:
AI helps machines learn from data and perform tasks such as recognizing faces, understanding voice commands, and controlling traffic.

2. How is AI helpful in homes?

Answer:
AI helps in homes by automating daily tasks like lighting, temperature control, and security.

Explanation:
Smart homes use AI to learn user preferences and save energy by automatically adjusting devices.

3. How can traffic be controlled using AI?

Answer:
AI controls traffic by analyzing data from cameras and sensors to manage traffic signals.

Explanation:
AI helps reduce congestion by changing signal timings based on real-time traffic conditions.

4. What is the main goal of intelligent security in smart cities?

Answer:
To improve surveillance and threat detection.

Explanation:
AI systems monitor CCTV cameras and detect unusual activities, improving public safety.

5. Which technology is used to monitor traffic on smart highways?

Answer:
Roadway sensors.

Explanation:
Roadway sensors collect data about vehicle speed and traffic flow to improve road safety.

6. What is facial recognition?

Answer:
Facial recognition is an AI technology used to identify people by analyzing their facial features.

Explanation:
It is commonly used in security systems and mobile phones for identification.

7. What are autonomous vehicles?

Answer:
Autonomous vehicles are vehicles that can drive themselves using AI.

Explanation:
They use sensors, cameras, and AI software to avoid accidents and improve traffic flow.

8. How does AI improve safety on smart highways?

Answer:

1. Java Keyword 👉 Definition: Keywords are reserved words in Java that have special meaning to the compiler. They cannot be used as identifiers (like variable names). 👉 Example: class , public , static , void , int , if , else public class Example { public static void main(String[] args) { int number = 10; // 'int' is a keyword if(number > 5) { // 'if' is a keyword System.out.println("Number is greater than 5"); } } } 2. Java Token 👉 Definition: A token is the smallest unit in a Java program. 👉 Types of Tokens: Keywords Identifiers Literals (numbers, characters, strings) Operators ( + , - , * , / ) Separators ( ; , {} , () ) 👉 Example: int a = 10; // Tokens: int, a, =, 10, ; 3. Java Data Types 👉 Definition: Data types define the type of data a variable can store. Two categories: Primitive Data Types (8 types) byte → 1 byte (e.g. byte b = 100; ) short → 2 bytes (e.g...
