Dot net is not network enabled technology, it's just a platform. NET provides tools and libraries that enable developers to create Windows software much faster and easier. .NET benefits end-users by providing applications of higher capability, quality and security. The .NET Framework must be installed on a user’s PC to run .NET applications.
