What is CDN?
A network of servers around the world that stores copies of your content closer to users
Why It Matters
CDNs make your website faster globally by serving content from the nearest location to each user
Real-World Example
A user in London loads images from a European server instead of waiting for them from Australia
“Understanding terms like CDN 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.”
