🔹 Answer: (A) Mobile phones, vehicles, and various devices

🔑 Key Points:

GPS stands for Global Positioning System.

It is used to determine the exact location of an object or person on Earth using satellites.

GPS is commonly integrated into mobile phones, cars, navigation systems, drones, smartwatches, and delivery services.

📌 Important Point:
GPS helps in navigation, tracking, emergency services, and even agriculture and disaster management.

ℹ️ Additional Info:

GPS was developed by the United States Department of Defense, but is now available for civilian use globally.

It works using a constellation of at least 24 satellites orbiting the Earth.

🔹 Answer: (C) Viewing stars, planets, and constellations

🔑 Key Points:

Stellarium is a planetarium software that shows a realistic sky in 3D, just like what you would see with the naked eye, binoculars, or a telescope.

It helps users explore the night sky, identify stars, planets, constellations, and celestial events.

🔹 Answer: (C) Vinton G. Cerf

🔑 Key Points:

Vinton G. Cerf, along with Robert E. Kahn, is widely recognized as the "Father of the Internet".

He played a leading role in developing the TCP/IP protocols, which form the foundation of the Internet.

These protocols enabled inter-networking – connecting multiple networks into a single global network (the Internet).

📌 Important Point:
The successful development and standardization of TCP/IP protocols by Vinton Cerf was a critical milestone in the creation of the modern Internet.

ℹ️ Additional Info:

Tim Berners-Lee is credited with inventing the World Wide Web, which runs over the Internet.

Vinton Cerf also worked with DARPA (Defense Advanced Research Projects Agency) during the early stages of Internet development.

🔹 Answer: (A) Google, DuckDuckGo, Yahoo, Bing

🔑 Key Points:

Search engines are tools used to search for information on the internet.

Examples include:

Google – The most widely used search engine.

DuckDuckGo – Known for privacy-focused search.

Yahoo – A web portal with a search engine.

Bing – Developed by Microsoft.

📌 Important Point:
Search engines are different from social media, productivity apps, or streaming services — they help users find web content efficiently.

ℹ️ Additional Info:

Search engines use web crawlers to index pages and algorithms to rank and return results based on user queries.

Some search engines, like DuckDuckGo, are known for not tracking user activity.
