The loopback adaptor has nothing to do with any physical hardware: it's a service provided internally by the operating system.

2localhost is an internal IP address, which is handled directly by the kernel. No external network is involved (thus no network card). Is is used to handle "network" connections to the same machine. – vonbrand – 2013-03-14T09:58:50.203
