In computer networking, localhost is a hostname that means this computer. It is used to access the network services that are running on the host via its loopback network interface. Using the loopback interface bypasses any local network interface hardware.
On most computer systems, localhost resolves to the IP address 127.0.0.1, which is the most commonly used IPv4 loopback address, and to the IPv6 loopback address ::1.

type ipconfig(Windows CMD) and ifconfig(Linux terminal) and you can see the local address.

If you type localhost  into your browser, then your browser will know that you want to connect your computer to a server. If your computer is running web server software like Apache, then your browser will be served a web page by your own computer.
