Internet, Web Browsing and Email Communication

This domain tests how the web actually works, how to search and browse efficiently, and how to use email fields and protocols correctly.

How the internet and web work

  • The internet is the global network of networks; the World Wide Web is one service running on it. Browsers work client–server: your browser requests a page over HTTP/HTTPS, and DNS translates the domain name into an IP address.
  • URL anatomy: https://school.example.in/notice?id=12 - protocol, domain, path, query. HTTPS with a padlock means the traffic is encrypted; it does not prove the site is honest.
  • Browser tools: address bar, tabs, bookmarks, history, cache, cookies, downloads. Incognito/private mode stops local history storage but does not hide you from your ISP, network or websites.
  • Search operators: "exact phrase" in quotes, -word to exclude, site: to limit to one site, filetype:pdf for a format.

Email essentials

  • Address: local-part@domain. Fields: To (person who must act), Cc (informational copy, visible to all), Bcc (hidden copy - use for large groups to protect addresses).
  • Protocols: SMTP sends mail; POP3 downloads it (often removing it from the server); IMAP keeps mail synchronised across devices.
  • Keep subject lines specific, quote context in replies, avoid reply-all, watch attachment size limits, and treat unexpected links or attachments as phishing until verified.

Worked example

A teacher must email 60 parents about a parents' meeting. Correct method: put the teacher's own address in To, and all 60 parent addresses in Bcc. Reasoning: each parent receives the message, but no parent can see another family's address - this avoids a privacy breach and spam complaints.

Traps that cost marks

  • Treating "internet" and "WWW" as synonyms.
  • Believing HTTPS guarantees a genuine site - always check the spelling of the domain.
  • Confusing Cc with Bcc.
  • Swapping SMTP (send) with POP3/IMAP (receive).
  • Claiming incognito mode makes you anonymous.
