The internet only works because devices agree to follow the rules. This module will test your ability to memorise definitions, categorise protocols, and apply them to real-world exam scenarios.
An agreed way of doing things.
A standard provides universal rules so that hardware and software from different manufacturers can interact (e.g., USB port shapes, Ethernet cables).
A specific set of rules for transferring data.
These govern exactly how messages are formatted, sent, and received across a network so devices can understand one another.
Categorise the following statements quickly. Remember the core definitions!
"An agreed way of doing things."
Categorise all items to continue.
Different protocols have highly specific jobs. You must memorise these four foundational rules.
Data packets are rolling in! Read the scenario and decide if it's safe to use HTTP (Plain text) or if it requires HTTPS (Encrypted).

SENDING ONLY
Used to send emails from your device to a mail server.
RECEIVING (Download)
Retrieves emails. It usually downloads the email and deletes it from the server.
RECEIVING (Sync)
Retrieves emails but leaves a copy on the server. Keeps your inbox synchronised across devices.
Read the envelope scenario. Click the correct server postbox to process the request.
Current Scenario
"I want to send an email with an attachment to my colleague."
Process all emails to continue.
Click a scenario on the left, then click the matching protocol on the right. This simulates a classic 4-mark OCR question.
Match all protocols to finish.
Excellent work, Student.
