Internet Kya Hai? What Is the Internet? Definition and Basic Concept

The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to communicate with each other. It is the largest Wide Area Network (WAN) ever created, connecting billions of devices, servers, and users across every country in the world.

The word Internet comes from ‘Interconnected Networks’. Every computer, smartphone, tablet, smart TV, server, and IoT device that connects to the internet becomes part of this massive global network. They all communicate using shared rules (protocols), primarily TCP/IP, which ensures that data sent from one corner of the world reaches the correct destination on the other side.

In Hindi, the Internet is called Antarjaal (अंतरजाल) or simply Internet (इंटरनेट). The term Antarjaal literally means ‘inter-net’ or ‘between networks’ in Sanskrit-derived Hindi.

Search Engines: How They Work and Popular Examples

A search engine is a web-based tool that allows users to search for information on the internet by entering keywords or phrases. The search engine scans its index of billions of web pages and returns the most relevant results based on complex ranking algorithms.

How a Search Engine Works

• Crawling: Search engine bots (called spiders or crawlers) systematically browse the web and discover new and updated web pages
• Indexing: The discovered pages are analyzed and stored in a massive database called the search index
• Ranking: When a user searches, the algorithm ranks indexed pages by relevance, authority, and hundreds of other factors
• Displaying Results: The ranked pages are shown as SERP (Search Engine Results Page) to the user

Search Engine	Owner / Company	Country	Market Share / Notes
Google	Alphabet Inc. (Google)	USA	World’s most used search engine; over 90% global market share; uses PageRank algorithm

Frequently Asked Questions (FAQs)

Q1. What is the Internet and who invented it?

The Internet is a global network of interconnected computers using TCP/IP protocols. It evolved from ARPANET, created by the US Department of Defense in 1969. The foundational TCP/IP protocol was designed by Vint Cerf and Bob Kahn in 1973, earning them the title ‘fathers of the internet’. The World Wide Web, which is the most popular internet service, was invented by Tim Berners-Lee in 1989.

Q2. What is the difference between the Internet and the World Wide Web?

The Internet is the global infrastructure of interconnected networks including cables, routers, servers, and protocols. The World Wide Web (WWW) is one service that runs on top of the internet. It consists of web pages linked by hyperlinks, accessed through browsers using HTTP/HTTPS. Other internet services like email, FTP, and VoIP also use the internet but are not part of the WWW.

Q3. What is the difference between SMTP, POP3, and IMAP?

SMTP (Port 25/587) is used for SENDING emails. POP3 (Port 110) is used for RECEIVING emails by downloading them to your device and removing them from the server. IMAP (Port 143) is also used for RECEIVING emails but keeps them on the server, allowing access from multiple devices. IMAP is preferred for modern multi-device use.

Q4. What is SaaS, IaaS, and PaaS in cloud computing?

SaaS (Software as a Service) delivers complete software applications over the internet, such as Gmail, MS Office 365, and Dropbox. IaaS (Infrastructure as a Service) provides virtual servers and storage, such as Amazon EC2 and Azure VMs. PaaS (Platform as a Service) provides a development platform for building applications, such as Google App Engine and Heroku. SaaS is the most commonly used type by end users.

Q5. What is e-commerce and what are its types?

E-commerce is buying and selling goods and services over the internet. The main types are: B2C (Business to Consumer, like Amazon and Flipkart), B2B (Business to Business, like Alibaba and IndiaMART), C2C (Consumer to Consumer, like OLX and Quikr), and G2C (Government to Citizen, like IRCTC and DigiLocker). G2B (Government to Business), C2B, and G2G are additional types.

Q6. Who founded Google, Facebook, and YouTube?

Google was founded by Larry Page and Sergey Brin in 1998. Facebook was founded by Mark Zuckerberg in 2004. YouTube was founded by Chad Hurley, Steve Chen, and Jawed Karim in 2005 and was later acquired by Google in 2006.
