I have been seeing reading and even downloading white paper but I don't understand how it works and it's purpose and application.
What is a 'White Paper'
A white paper is an informational document issued by a company to promote or highlight the features of a solution, product or service. White papers are sales and marketing documents used to entice or persuade potential customers to learn more about or purchase a particular product, service, technology or methodology. White papers are designed to be used as a marketing tool before a sale, and not as a user manual or other technical document developed to provide support to the user after making a purchase.
