Internet, Email and Web Basics
What this domain tests
This domain tests basic network and web vocabulary, URL and email structure, browser/search skills, and safe, polite online behavior.
Core rules
- The internet is the global network of networks; the World Wide Web is a service of linked pages on it.
- An IP address identifies a device; DNS translates a domain name into an IP address.
- A URL has parts: scheme, host, path, and optionally query and fragment.
- HTTP/HTTPS transfer web pages; HTTPS encrypts traffic between browser and server.
- Email address form: local-part@domain. To is the main recipient, Cc is a visible copy, Bcc is a hidden copy.
- Reply goes to the sender; Reply All goes to the sender and recipients visible in To and Cc.
- Search effectively with exact phrases in quotes, minus to exclude, and site: to limit a domain.
- Netiquette: clear subject, no ALL CAPS, quote only relevant text, respect privacy.
Worked example
Break down https://www.example.com/notice?id=5#top. Scheme: https. Host: www.example.com. Path: /notice. Query: id=5. Fragment: top. This tells you the page is requested securely from that host, the server receives id=5, and the browser is directed to the “top” section. The https part protects the connection; it does not prove the content is true.
Traps
- Using Bcc wrongly can expose or hide recipients; Bcc protects addresses from other recipients.
- Reply All can send a private reply to a whole list.
- A padlock icon means encrypted transport, not a trustworthy or official site.
- Typing a web address into a search box may lead to an advert or wrong site.
- Attachments may be blocked for size or for malicious content; never open unexpected ones.
