The meaning of ‘CDN’ in Network/Internet is ‘Content Delivery Network’.
Meaning of ‘CDN’
CDN stands for Content Delivery Network and is a system of distributed servers used to deliver web content to users. The idea behind a CDN is to provide an efficient method of delivering content to end users, regardless of their geographic location or speed of connection.
A CDN works by caching content on servers located throughout the world. When a user requests a webpage or file from the network, the request is routed through the closest server in order to reduce latency and improve performance. By distributing the content over different servers, a CDN can ensure that content is delivered quickly and reliably without being overloaded in any one region.
One of the most common uses of a CDN is for streaming media such as video or audio files. A CDN helps ensure that these files are delivered quickly and without interruption by having them stored on multiple servers so that if one server becomes overloaded, the other servers can take up the slack. This also helps prevent “hot spots” which can occur when too many users request data from one server at once.
Another popular use for CDNs is for websites with large amounts of static resources such as images, JavaScript files, and CSS stylesheets. By caching these resources on multiple servers, it reduces strain on the origin server and makes it easier to serve up these resources faster to end users no matter where they are located in relation to the origin server.
CDNs have become increasingly important as online traffic has increased exponentially in recent years due to mobile devices taking up more web traffic than ever before. As more websites rely on dynamic content pulled from databases or stored remotely in cloud services like Amazon S3 or Microsoft Azure Storage, having an efficient way to deliver this content fast is essential for providing good user experience.
In addition to reducing page loading times, using a CDN can also help protect against distributed denial-of-service (DDoS) attacks which involve overwhelming a website with fake requests from multiple sources in order to take it offline temporarily. By routing requests through multiple global locations spread out across multiple networks, it can make it much harder for attackers to bring down your website or service with an attack like this.
In summary, CDNs are an essential part of modern web infrastructure and are used all over the world by companies big and small alike in order to keep their websites running fast and reliably no matter where their visitors may be located geographically or what type of connection they may have available.
