What is the use of the Static Resources in Salesforce?

Hi Anjali,

Static resources allow you to upload content that you can reference in a Visualforce page. Resources can be archives (such as .zip and .jar files), images, stylesheets, JavaScript, and other files.
Static resources are managed and distributed by Lightning Platform, which acts as a content distribution network (CDN) for the files. Caching and distribution are handled automatically.

Static resources are referenced using the $Resource global variable, which can be used directly by Visualforce, or used as a parameter to functions such as URLFOR().
