What is DNS, HTTP, and Public_HTML?


You’ve probably heard about the world wide web before. But what exactly is it? It’s an endless topic. This article will discuss the DNS, HTTP, and Public_html directories. You’ll learn how these things work and why they’re essential. After all, the Internet is a global platform that’s constantly growing.

Hypertext transfer protocol (HTTP)

Hypertext transfer protocol is an application layer protocol of the Internet protocol suite. It is used for distributed hypermedia information systems. This protocol enables the transfer of text, graphics, audio, and video. It is widely used in the distribution of online books and other information. It is used in Internet browsers and intranet and extranet applications.

HTTP is used to transmit data between web browsers and servers. It uses an ASCII-like alphabet based on a server/client model. The client sends an HTTP request to the server and a corresponding response with HTML files or other content.

Domain name system (DNS)

DNS is a network protocol that links IP addresses and domain names. This allows you to find websites by name or send an email using that name. When you type a website’s URL into your browser, the DNS sends a query over the Internet that matches the domain to its IP address. The IP then fetches the website’s content. This process occurs within milliseconds.

There are several types of servers involved in the DNS. Some are registries that run top-level domains. They also maintain a database called zone files. Registrars sell domain names to website owners and usually offer additional services. The DNS system is overseen by an organisation called ICANN.


HTTP, or HyperText Transfer Protocol, is a set of rules that mediate communication and data transfer between links on the Internet. The protocol is a vital part of the Internet and carries requests from your computer to a web server. It also helps you post content to servers, fetch parts of documents, and update Web pages on demand.

HTTP, the HyperText Transfer Protocol, defines the data transfer standard between web servers and browsers. HTTP also defines the format of web pages and the structure of the messages it sends and receives.

Public_html directory (www)

The WWW and Public_html directories are used to store website files. While WWW is usually a physical folder on your host, it can also be a link to the PUBLIC_HTML directory. The WWW directory is best iTthereforef you want to keep a copy of your website.

You can find the Public_html directory in the root directory of your cPanel account. In cPanel, the path to this folder is /home/username/public_html/. The /home/username is your cPanel username.


The “www” prefix is a standard convention of the Internet. This allows websites to have the same address as other domains. While most users cannot tell the difference between a non-www website and a www site, search engine crawlers do. Googlebot, for example, treats non-www pages as duplicate content. So, you may consider whether or not to use the “www” prefix on your website.

The protocol, or “web address,” is the URL part that tells the browser to send information to the server. Most modern web browsers do not require the user to enter this information. Domains are usually composed of many computers. Paths are a subset of the domain.
