Content Delivery Network also known as CDN plays an important part as far as a website owner or a blogger is concerned.
What is CDN?
A content delivery network, or content distribution network (CDN), is a geographically distributed network of proxy servers and their data centers.
Why Use CDN?
The idea behind CDN is to deliver the data by distributing it over different server, located in different part of the world, so that the data can be easily available, with high end performance.
If a data is stored on a single server, high number of request to retrieve that data can cause the server to fail, resulting in crashing of the website. This problem can be solved by distributing that data over different locations, with the help of CDN, so the the load on the servers can be minimized and high end performance can be achieved.
