What is Latency?

The time delay between a request and its response

Why It Matters

Lower latency means faster, more responsive applications that users enjoy using

Real-World Example

A button that responds in 50ms feels instant, while 2000ms feels sluggish

“Understanding terms like Latency matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
