What is Localhost? Explained for Beginners - MyThemeShop

There are so many technical jargons that are commonly used while discussing networking, server management, and data transfer. One can easily get confused.

One such term is “localhost”. If you are also confused and scratching your head, thinking what exactly is localhost, stick tight as we will be discussing the same in detail.

The internet is a large network that works on a certain set of parameters and rules. It takes a lot of bandwidth perse to transfer, view, and upload any information on the internet.

You must have come across terms like localhost, local machine, home machine, or patterns like 127.0.0.1. The important question is, what is localhost, and what does it really do?

1 What Exactly is localhost?

Let us try to explain the same using an example. Let’s say you are trying to connect to https://mythemeshop.com. It is a domain name which is located at a certain IP address.

We usually connect to websites using their domain names (like mythemeshop) instead of their IP address due to the obvious reason – domain names are easier to remember as compared to an IP address like 192.0.2.1.

When you are trying to connect to 127.0.0.1, it will always connect to your own system, or let’s say your own PC.

In short, localhost is your own computer that has a default IP address of 127.0.0.1. You try to connect to 127.0.0.1 on any PC or computer, that will connect you to the same computer.

Localhost is the server that is used by your own computer. The term is majorly used in the context of networking.

2 What is localhost used For?

As you know that it takes a certain bandwidth to communicate on the internet. Localhost was primarily created so that developers, network engineers could test things on their own local system first before taking it live on the main server or the internet.

Let’s say we at MyThemeShop want to test out a new design for our website. Before going live, we want to make sure that all the functionalities in the new design work absolutely fine. For eg: the payment gateway, file download, content structure work absolutely fine after we implement the new design.

Though, before directly taking the new theme design live on the website, we would first want to test all the functionalities.

In order to test the same, we can use the localhost, i.e. create our own computer as a server, test the functionalities of the new theme. Once we test all the functionalities, we can then take the theme live on our website.

This would help us transition from our old design to a new design seamlessly without breaking any functionality on the website.
