Getting Connected Internet

Given: A list of website addresses whose purposes are to be identified.

Concept: Every website is created for a specific purpose. By visiting the website and reading its home page, one can identify its purpose.

Solution:

| Website Address | Purpose |
|---|---|
| mygov.in | A citizen engagement platform of the Government of India where citizens can participate in governance, share ideas, take polls, and contribute to government initiatives and campaigns. |
| swayam.gov.in | A national online education platform (Study Webs of Active Learning for Young Aspiring Minds) that offers free online courses from school level to post-graduation, conducted by top faculty of Indian universities and institutions. |
| ndl.iitkgp.ac.in | National Digital Library of India — a virtual repository of learning resources including books, articles, theses, and other academic content for students and researchers at all levels. |
| farmer.gov.in | A portal dedicated to farmers (Kisan Suvidha) providing information on weather, market prices, plant protection, agri-inputs, and government schemes related to agriculture. |
| ors.gov.in | Online Registration System — a portal that allows citizens to register and book appointments at government hospitals and health centres across India. |

Conclusion: Each website serves a distinct public service purpose — governance, education, digital library, agriculture, and health respectively.

Given: Three email IDs to be checked for validity.

Concept: A valid email ID must follow the format: username@domainname.extension
- It must contain the '@' symbol separating the username from the domain name.
- The username can contain letters, numbers, dots (.), underscores (_), and hyphens (-).
- There must be a domain name followed by a dot and an extension (e.g., .com, .in).

Analysis of each email ID:

| Email ID | Valid / Invalid | Reason |
|---|---|---|
| Aayush. gmail.com | Invalid | It does not contain the '@' symbol. A dot (.) has been used instead of '@' to separate the username from the domain. The correct format should be Aayush@gmail.com |
| School_yahoo.com | Invalid | It does not contain the '@' symbol at all. The underscore (_) has been used instead of '@'. The correct format should be School@yahoo.com |
| Suhana@rediffmail.com | Valid | It follows the correct format — username (Suhana) + @ symbol + domain name (rediffmail) + extension (.com). |

Conclusion:
- Email IDs (i) Aayush. gmail.com and (ii) School_yahoo.com are invalid because they are missing the mandatory '@' symbol.
- Email ID (iii) Suhana@rediffmail.com is valid.

Given: A list of keywords prepared for searching information on the topic 'Green Revolution'. We need to identify which keywords are NOT much useful.

Concept: The Green Revolution refers to a period (mainly 1960s–70s) of agricultural transformation that involved the development of high-yielding varieties of crops (especially wheat and rice), use of fertilisers, pesticides, and irrigation to increase food grain production. Effective keywords should be specific and directly related to the topic.

Analysis of each keyword:

| Keyword | Useful / Not Much Useful | Reason |
|---|---|---|
| Agriculture | Not much useful | Too broad and general. Searching 'Agriculture' will give millions of unrelated results not specific to Green Revolution. |
| Norman Borlaug | Useful | He was the father of the Green Revolution and developed high-yielding wheat varieties. Directly relevant. |
| M.S. Swaminathan | Useful | He is known as the father of the Green Revolution in India. Directly relevant. |
| Wheat farming | Useful | Wheat was the primary crop of the Green Revolution. Relevant and specific. |
| Dairy farming | Not much useful | Dairy farming is related to the White Revolution (Operation Flood), not the Green Revolution. Not relevant. |
| Fish farming | Not much useful | Fish farming is related to the Blue Revolution, not the Green Revolution. Not relevant. |
| Crop yield | Useful | Increasing crop yield was the main objective of the Green Revolution. Relevant. |
| Genetically modified crops | Useful | Related to modern agricultural biotechnology which evolved from Green Revolution research. Relevant. |
| Biotechnology | Not much useful | Too broad. While biotechnology has some connection, the keyword alone will not give specific Green Revolution results. |

Keywords that are NOT much useful:
1. Agriculture — too general and broad.
2. Dairy farming — related to White Revolution, not Green Revolution.
3. Fish farming — related to Blue Revolution, not Green Revolution.
4. Biotechnology — too broad; not specific to Green Revolution.

Conclusion: To get precise and relevant search results about the Green Revolution, one should use specific keywords like Norman Borlaug, M.S. Swaminathan, Wheat farming, Crop yield, and Genetically modified crops, and avoid overly broad or unrelated terms.
