01

Understand the idea

Download speed describes throughput while latency describes response delay. A fast download test can coexist with delayed interactive responses.

Context
02

Practical step
03

Know the limits

A single speed-test result does not measure the performance of every website or server.

Important limit

Make the reading useful.

Take a moment to check your understanding. This is a reflection aid, not a certification or account check.
