What is a CDN?

Content Delivery Network (CDN). A globally distributed network of servers designed to accelerate the loading of web resources (static files: images, videos, CSS, JavaScript, etc.) for end-users.

How it works:

• Content is copied to multiple servers located in different geographical locations.
• When a user requests content, the CDN determines the nearest server.
• Content is delivered to the user from the closest server, reducing latency and speeding up loading.

Advantages of using a CDN:

• Faster loading: Users access content more quickly.
• Reduced load on the main server: Part of the traffic is handled by CDN servers.
• Increased availability: If one CDN server is unavailable, requests are redirected to others.
• Improved SEO: Site loading speed is a ranking factor in search engines.

Example of using a CDN to connect a library:

<!-- Connecting jQuery via CDN -->
