A Namespace in computer science (sometimes also called a name scope) is an abstract container or environment created to hold a logical grouping of unique identifiers or symbols (i.e., names). An identifier defined in a namespace is associated only with that namespace.(Wikipedia: https://en.wikipedia.org/wiki/Namespace#:~:text=A%20namespace%20in%20computer%20science,associated%20only%20with%20that%20namespace.)
