What is localhost?

Localhost is a special word that refers to the computer you're using right now. When you use a website or program, it has to communicate with other parts of the computer, like the web browser or server. When a program is set to use localhost, it means it's only communicating with itself on your computer.

In web development, developers use localhost to test their websites and apps before they're published online. This allows them to make sure everything works correctly and looks good before other people can see it. It's like trying on a new outfit at home before going out to show it off to others.

So, in summary, localhost is the computer you're using right now, and it's used in web development to test websites and apps on your computer before they're shown to others online.

Based on the image provided, it appears that the user is highlighting the IP address 192.168.1.9 which is associated with the eth0 network interface. This indicates that the user's machine is configured to use the eth0 interface for connecting to the internet and that the highlighted IP address is the machine's local IP address.

Local IP addresses are used to identify devices on a local network and can be used to access local resources such as a local server or the local host address. In this case, the user can access a local server running on their machine by entering the local IP address (192.168.1.9) into their web browser.

http://192.168.1.9:port
