Internet, Web Browsing, Email and Digital Communication
This domain tests how the internet and web work, how to browse and search effectively, and how to use email professionally and safely.
Core concepts
- The internet is the global network of networks; the World Wide Web is a service on it made of linked pages.
- A URL has a scheme, domain, path, and sometimes a query, as in https://example.com/page?id=5. HTTPS encrypts traffic between browser and site.
- A browser renders pages; search operators such as quotes, site:, and filetype: narrow results.
- Email fields: To is the main recipient, Cc is a visible copy, and Bcc is a hidden copy.
Worked example
A school must email 300 parents and hide all addresses from one another. Put the school's own address in To and all parent addresses in Bcc. The reasoning is that Bcc recipients do not see one another's addresses, which protects privacy. Putting them in Cc would expose every address.
Traps that cost marks
- Using Reply All when only the sender needs a reply.
- Treating Cc as hidden; Bcc is the hidden field.
- Clicking shortened or mismatched links in unexpected emails.
- Assuming HTTPS guarantees a trustworthy site; it only secures the connection.
