In one sentence
Clients send requests over a network, and servers process them and return responses.
Key points
- A client initiates a request; a server listens, processes it, and returns a response.
- DNS, networking, compute, and application layers cooperate to complete a request.
- Cloud services still use this model even when servers are managed or hidden by serverless abstractions.
Exam takeaway
Understanding request paths helps identify latency, availability, and security boundaries.
