Basically the content in a website can be categorized into to categories: * Dynamic content - generated by CMS like Drupal, Wordpress, or custom script like php, ASP etc. This content is dynamically assembled and severed to the browser hence called as Dynamic.
* Static Content - as the name implies this content does not change with request and is static. All multimedia things like image, audio, documents etc. come under this category.As your website traffic grows, your web server can get busy serving serving all these dynamic + static content. So in order for you site to handle more requests efficiently you can setup you main server to serve only the dynamic content and setup another server to server the static content, thus increasing the website capacity to handle more visitors.
