Bring the ideas back
Outcome: Recall and apply the central ideas from the lessons due today without rereading them first.
Before you begin
Try each prompt from memory. Then reveal the model answer and compare the idea, not the exact wording. If the idea is unclear, reopen the original lesson after the attempt. Completion still requires your confirmation.

What “AI” usually means in everyday tools
Software that has learned patterns from large amounts of data and uses those patterns to produce predictions, suggestions, content, or decisions when it receives new input.
Example: phone camera — input is a low-light photo; output is a brighter, clearer image produced by patterns learned from many previous images. (Other valid: autocomplete, traffic prediction, chatbot reply.)

What opportunity cost is and how it helps everyday decisions
The value of the next-best alternative you give up when you choose one option. It is not only money; it includes time, attention, and other resources.
Example: spending an evening watching videos instead of practising a skill — the opportunity cost is the progress or practice you did not get. (Any clear “chosen option vs next-best forgone alternative” is valid.)
Reopen the original lesson after attempting both questions (note: the file may still be a short placeholder if the full lesson was not finished earlier).

How to explain an idea clearly using Context, Point, and Example
Context (set the situation), Point (state the main idea clearly), Example (give one concrete illustration).
Context orients the listener so they know why the idea matters; the point then lands clearly; the example makes it concrete. Without the structure, details can feel floating and hard to remember.

How DNS helps your browser find a website
DNS translates the human-readable domain name into the numerical IP address the computers on the network actually use to reach the server.
You can keep the same easy-to-remember name even if the server’s IP address changes (for example when a site moves to a new host). DNS is the lookup that keeps the two linked.
