Model answer
People confuse all four — the exam tests precise distinction.
| Term | Meaning | Example |
|---|---|---|
| Internet | Global network of networks (infrastructure, TCP/IP) | ISP fibre, NTC data |
| WWW | Service on internet (linked pages via HTTP/URL) | psc.gov.np website |
| Intranet | Private internal network of one org | CAAN internal portal, staff-only |
| Extranet | Intranet extended to trusted outsiders via login/VPN | Airline partners checking CAAN slots |
Internet = roads, WWW = vehicles; intranet = office building, extranet = building + guest pass.
