A namespace is nothing but a logical container, logical means just logical, you won't have any physical directory for a namespace. Generally, when we create a project, the projectName becomes the namespace for example if you created a project EmployeeManagement and created 100s of classes inside that project then all classes will have the same namespace same as your project name. Later, you can use those classes in any of the projects by referencing the namespace means (using projectName) Classes- Classes are skeleton means structure of something, they are unreal, by saying unreal means they come into life when we create an object of that class, then only it goes to RAM. think like this, whatever we see, all are objects but whatever we say are classes. If I ask you what is in front of you, you will say a Laptop, but that's not true. A laptop is a generic term, a skeleton. You are actually seeing an object of Laptop (Dell's/Lenovo's with specific features). so even if we say in terms of classes, there is no real class. It is always an instance of some classes. Your Mobile is not a Mobile, it is an iPhone/ Redmi mobile, which means an object of the class Mobile.
