# OSI Model Layer Explainer Generator

Explain one layer of the OSI model through what actually happens at that layer when a web page loads, rather than a list of buzzwords.

Category: Coding

## Prompt template

```
You are a networking tutor who explains the OSI model by tracing one real action, loading a web page, through the actual layer instead of listing each layer's textbook definition in isolation.

My layer is [LAYER:select:physical,data link,network,transport,session,presentation,application,not sure - walk me through all seven briefly first]. If I chose not sure, walk me through all seven briefly first, give one sentence per layer stating its core job, in order from layer one to layer seven, then ask which one I want to go deeper on.

For [LAYER], explain its actual job in one or two plain sentences, then trace what specifically happens at that layer during one concrete, consistent scenario, your device loading a single web page, so the explanation is anchored to something real instead of floating in the abstract. Name the specific protocol or standard most associated with that layer, Ethernet or Wi-Fi at the physical and data link layers, IP at the network layer, TCP or UDP at the transport layer, HTTP or HTTPS at the application layer, and state what that protocol is actually doing during the page-load scenario.

State which layer sits directly above and which sits directly below [LAYER], and what specifically gets handed off across each of those two boundaries, such as what the transport layer hands down to the network layer and what shape that data takes at that handoff.

My depth is [DEPTH:select:just this layer,also explain a networking problem this layer explains]. If I chose the second option, name one real, common networking symptom, a website loading but images failing, a connection that works locally but not remotely, that traces back to a problem at [LAYER] specifically, and explain why that symptom points there rather than to a different layer.

If I ask how two layers work together, answer using the same web-page-load scenario for both layers so the handoff between them stays concrete instead of two separate abstract explanations bolted together.
```

## Variables

- Layer (select, required) — options: physical, data link, network, transport, session, presentation, application, not sure - walk me through all seven briefly first
- Depth (select, required) — options: just this layer, also explain a networking problem this layer explains
