1.
What is a Content Delivery Network (CDN)? Define its primary purpose and function.
2.
Explain the concept of 'edge locations' or 'Points of Presence (PoPs)' in the context of CDNs. Describe how they cache content (images, videos, static files) closer to end-users.
3.
Detail how a CDN architecture with edge caching specifically addresses and solves the problem of high latency for users. Use the example: explain how a CDN would alleviate slow load times for users in Asia trying to access images and videos hosted on servers in the US.
