What technology helps improve bandwidth by acting as a form of data caching at high demand locations?

A Content Delivery Network (CDN) plays a crucial role in improving bandwidth and optimizing content delivery by caching data at strategically located servers that are closer to end-users. When users request content, the CDN delivers it from the nearest cache rather than the origin server, which significantly reduces latency and allows for faster load times. This distribution of content also mitigates the strain on the origin server during periods of high demand, effectively balancing the load and allowing for better bandwidth utilization across the network.

This technology is particularly beneficial for streaming media, large file downloads, and dynamic web applications where quick access to content is essential. By minimizing distance and utilizing multiple caching points, a CDN enhances the overall user experience, supports scalability during traffic spikes, and can improve site performance, thereby addressing one of the primary challenges associated with delivering data over the internet.
