Internet, Web Browsing and Email
What the domain covers
Internet, Web Browsing and Email tests how the internet differs from the web, how URLs and browsers work, how to search effectively, and how to use email fields safely.
Core rules
- The internet is the global network of networks; the World Wide Web is one service on it, made of web pages linked by URLs. An ISP provides access.
- URL anatomy:
scheme://host/path?query.httpsis HTTP over TLS (encrypted);httpis not. A browser stores cache and cookies; private/incognito mode does not make you anonymous to the network or websites. - Search operators: quotes for an exact phrase,
site:to limit to a domain,-to exclude a word,filetype:for a file type. - Email fields: To for action recipients, Cc for visible information recipients, Bcc for hidden recipients. Reply goes to sender; Reply All goes to all listed recipients; Forward sends to new people.
- Attachments should be relevant and scanned; never open unexpected attachments.
Worked example
https://school.example/notes/it.html?page=2 has scheme https, host school.example, path /notes/it.html and query page=2. For a class announcement, put all parents in Bcc and your own address in To: recipients then cannot see each other’s email addresses, which protects privacy.
Traps
- Treating Cc and Bcc as the same; Cc is visible.
- Using Reply All for a reply meant only for the sender.
- Calling
http://secure because a padlock icon is expected - check the actual scheme. - Confusing an email address (
name@domain) with a URL (https://domain).
