So, to answer your question - yes, they are different. localhost is given an ip address in the 127.0.0.0 network and given to a virtual loopback network device lo. This device is present on all systems, regardless of whether they have a physical network device fitted (WiFi or Ethernet, for example).
ping is another simplest way of finding IP address of localhost or any other host in network, if you know the hostname or computer-name just ping and it will display IP address associated with it. Normally pint command is used to check if a host is alive and connected with network.
