Networking & Internet Services
Internet & Web Infrastructure
Core concepts required for board short-answer questions:
- World Wide Web (WWW): A global hypertext system of linked documents accessed over the internet using HTTP/HTTPS.
- Web Server vs Web Client: A server (e.g. Apache, IIS) hosts website resources and answers HTTP requests; a client (browser) requests and renders them.
- Web Address (URL) vs E-mail Address: A URL specifies protocol and domain path (
https://site.org/page), while email uses mailbox routing ([email protected]). - Downloading vs Uploading: Downloading fetches files from a remote server to local storage; uploading sends files from local machine to remote host.
Internet & Transfer Protocols
Standard communication rules prescribed in the syllabus:
| Protocol | Full Form | Port | Function |
