A "Package", the name seems very familiar but what exactly is a package when it comes to a web hosting manager. As the names itself says its meaning. Yes!!! it's a collection. But when you ask "what ?" the answer is "The collection of some predefined specifications". Thus a package can be explained as a collection of predefined specifications which define what a user or domain may have access to. WHM should have at least one package configured to start creating new user accounts with it.
