The acronym CDN stands for Content Delivery Network. It is an interconnected system of cache servers that utilize geographical proximity as a condition for distributing web content. The content in a content delivery network exists as numerous copies on tactically dispersed servers. If a content delivery network is big, it can have thousands of servers around the world.
This makes it possible for the provider to transmit the same content efficiently and reliably to numerous requesting client computing devices even if the bandwidth is limited. The content delivery network is handled by the CDN management software. The software dynamically analyzes which server is closest to the client and then sends the content based on the calculations.
This process will not only reduce the distance that the content must travel to reach the destination but also decreases the number of hops that a data packet should make.
