Quick-Revision Knowledge: Revision and References

Module CA-11 — Consolidated final revision#

Use this table as a last-minute check, not a substitute for reading the preceding explanations. When a row seems unfamiliar, return to its corresponding lesson and the earlier module indicated.

One-page self-testing method#

1. Read a heading (for example, network protocols) and recall four names before looking at its table.
2. For each name, give one job and one easily confused neighbour: SMTP sends; IMAP accesses a mailbox.
3. Attempt the associated 12 MCQs without notes, then read every answer explanation, including correctly guessed answers.
4. Mark uncertainties in three columns: acronym, concept pair, and historical fact. Review the matching earlier lesson ID rather than repeatedly memorizing the same wrong association.
5. On the next review, try applied scenarios first. Recognizing the correct answer when choices are visible is easier than recalling it independently.

Master exam traps to avoid#

• Do not use CPU as a synonym for the entire desktop cabinet.
• Do not confuse a unit's printed symbol: MB and Mb differ by a factor of eight.
• Do not treat Unicode as identical to the ASCII coding scheme.
• Do not assume Web, Internet, browser and search engine are interchangeable.
• Do not assume an encrypted link guarantees that the site using it is honest.
• Do not mistake scanned QR for NFC, which is radio communication.
• Do not accept a blanket “first computer” claim without knowing the qualifying definition.
• Do not confuse receiving money with authorizing a payment request.
