Complete web development tutorial 2021


A website can be defined as a collection of several webpages that are all related to each other and can be accessed by visiting a homepage, using a browser like Internet Explorer, Mozilla, Google Chrome or Opera. In this tutorial, we will explain the concept of website development, from the simplest to the most advanced. It will help novice users to learn all about websites and how they are designed and maintained. At the same time, this tutorial has enough material to help even system administrators to broaden their knowledge about websites.


This tutorial is meant for all those readers who would like to understand the entire process of setting up a well-designed website. We strongly believe that this tutorial will help almost everyone who wants to set up a website, without having to take professional guidance from a technical person.


We have designed this tutorial, keeping in mind the requirements of beginners, especially those who come from a non-technical background. Hence, we don’t assume any existing knowledge of website development from the readers.

Website Development - Introduction

A website can be defined as a collection of several webpages that are all related to each other and can be accessed by visiting a homepage, by using a browser like Internet Explorer, Mozilla, Google Chrome, or Opera. For example, the website address of Homekazi is −

  • The protocol used to access the website, which in this case is http, meaning port 80. It can also be https; port 443.

  • The subdomain which by default is www.

  • The domain name; domain names are normally chosen to have a meaning. Like in our case “tutorialspoint”, we can understand that this website offers tutorials.

  • The suffix name which can be .com, .info, .net, .biz, or country specific. For detailed information, please refer the following Wikipedia link −

  • The directories or in simple words, a folder in the server that holds this website.

  • The webpage that we are looking at, in our example, it is “about_careers.htm”.

  • Why Do We Need Websites?

    Websites primarily act as a bridge between one who wants to share information and those who want to consume it. If you are running a business, then it is almost imperative for you to have a website to broadcast your offerings and reach out to potential clients at a global stage.

    The following points explain why it is important to have a website −

  • A website is an online brochure where you can advertise your business offers.

  • It gives you a platform to reach out to a far-and-wide global customer base.

  • If you are a blogger, you have the possibility to influence your readers.

  • You can show all your ideas and publish them on a website.

  • If you have a business idea, then you don’t have to wait. You can straightaway open an online shop and sell your products or services online. An added advantage is that the online shop will be open 24/7 for your clients, throughout the year.

  • How to Setup a Website?

    A website is composed of several elements and while setting up a website, you would have to take care of each of them.

  • To set up a website and make it live, you should first purchase a hosting plan.

  • Select a domain name for this website.

  • Point the DNS records to the server or the hosting provider.

  • Develop the content that you want to publish on the website.

  • Check if you need to purchase a public certificate and install it.

  • Publish the webpage on the Internet.

  • In the subsequent chapters of this tutorial, we will discuss each of these steps in detail.

  • The skills required to set up a website can vary from very basic to the most advanced. If you are going to set up a professional website for a global audience, then you should have the following set of skills or you would have to hire a group of people to do this job for you.

    Content Experts

    Content experts supply the content that is to be published on the website. They design the content as per the requirement of the target audience and then, edit and polish the content before it gets published.

    Content experts normally rely on the expertise of the site designer and the webmaster. Note that the content can be text, data, images, audio or links.

    Website Designer

    A web designer is a technical person who designs and maintains the Graphical User Interface (GUI) of the website. For example, where the buttons should be placed, how the images are to be displayed, etc.

    Graphic Designers

    Graphic designers develop image files that are to be included in the website. These professionals have a keen understanding of developing suitable graphics for the web environment.

    Web Developers

    Web developers create the program codes to manipulate the supplied content, based on the site design established by the website designer. A web programmer should use a set of programing languages to compile specific functions that the webpages should do in the background. Here is a set of important programing languages that a web programmer must be good at −

  • HTML / XHTML − These are the markup languages which you will use to build your website. A web programmer must have a good understanding of HTML and XML.

  • PHP − It is a popular programming language to develop webpages. You can collect more information on PHP on − .

  • PERL Script − PERL is another language which is being used to develop interactive Web Applications. If you are planning to use PERL to develop your website, then please browse our tutorial – to know more about PERL.

  • Java or VB Scripts − These scripts are required to perform user-level validations and to add more interactivity to your Website. So, a web developer is required to have adequate knowledge of any of these client-side scripts.

  • AJAX Technology − AJAX is the latest technology on the Web. Google and Yahoo are using this technology to give a better browsing experience to their website visitors.

  • ASP or JSP − Web developers are required to be well-versed with ASP or JSP to develop interactive websites. 

  • Macromedia Flash − You can use Macromedia Flash to build a Website. It can be a little time-consuming to learn this technology, but once you learn how to use it, then you can develop attractive websites using Flash.

  • Hardware and Software Support Resource

    The Support Resource upgrades the hardware and software as and when needed. They play a crucial role in keeping the system up and running in a flawless manner.

    Marketing and Promotion

    Marketing professionals mostly use popular Social Media Platforms such as Facebook and Twitter to promote the content and resources available on the site. They reach out to the target audience and create awareness among them.

    System Administrator

    A System Administrator knows how to set up and point the protocols as HTTP, FTP, SMTP and DNS records. System administrators are those experts who look after every aspect of website development and its maintenance.

    Web Researcher

    You should research on new tools, trends and issues affecting the web technology. Web researchers report to the webmaster regarding new techniques that can be integrated in the website. They optimize appropriate site traffic and evaluate site development tools, which can be either hardware or software.

  • You can communicate with your customers, giving them an opportunity to express themselves.

  • You can provide valuable customer support by having a trouble-ticket system.

  • If you have an official website with a domain, then you can have your personalized email. For example, (it is much better than Development - Domain Name

Website Development - Domain Name

Domain name is the part of your online address and your visitors will use it to find you easily. For example, homekazi domain name is Your domain name is unique to you. Once you have registered it, nobody else can register the same one if you continue to renew it.

Registering a domain name can be easy because you can select whatever name you want, but what you choose is crucial for your business future or your blogging website. So, in this section, let us focus on some rules that we must keep in mind before we purchase a domain name.

Rule 1 − Choose a domain name that can be your brand name, if required. Our domain name is really branding because there is no generic keyword string like that can be hard to memorize where the ‘–’ is located.

If your brand doesn’t have numbers don’t purchase a domain with numbers because there is no brand matching from the user perspective. For example,

Rule 2 − If you have the financial possibilities, then you can purchase domains with various extensions such as .com, .net, .info, .biz, etc. In our case, it would be like,, There are domains that are misspelt, such as a similar case is If you write one ‘o’ is missing, but still it will redirect you to the official website

Google Page

Rule 3 − You must ensure that this domain name is not a trademark or is copyrighted.

Rule 4 − Find a short domain name. The lesser the characters in a domain name, the easier it is to type, to say, to share and to get shortlisted on social media platforms and in search results.

Rule 5 − Extensions are suffixes, such as .com or .net, at the end of the web addresses. These can have specific use, so ensure to choose an extension that works for your business. The .com domain extension is by far the most popular, but it can be tough to get a short and memorable .com domain name because it is around for so long. If your webpage is serving locally, then you can buy it with the suffix of your country.

Rule 6 − If your domain name is not going by the brand name, then at least you should use specific keywords which describes your business, for example, It helps improve your rank on search engines (which increases traffic) and it also makes more sense to your customers.

Domain Name Extensions

First domain type is Top Level Domain (TLD). These top level domains include any extensions which contain only one suffix — for example, .net, .info, .biz and so on.

Second Level Domains (2LDs) are domain names containing one more level after the .com or .co suffix. For example, is a second level domain style as it contains an additional suffix after the .com that shows the website originates in Australia.

gTLD is a Generic Top-Level Domain and includes addresses like – .marketing, .estate, .fashion and .photography. This is a booming segment which is very popular recently and there is a huge range to choose from, whatever your industry!

CcTLDs are Country Code Top-Level Domains which are usually restricted to certain countries. These are domains like .au, .uk, .ae, .us, etc.

Extension also has a meaning. The meanings of some top-level domains are listed as follows −

  • .com – commercial − This is an open TLD; any person or entity is permitted to register and it is always the main TLD.

  • .org – organization − This is an open TLD; any person or entity is permitted to register. But, it is originally intended for use by any non-profit organizations. But as of now, there are no such restrictions and the .org domain name is being used by numerous organizations.

  • .net – network − This is an open TLD; any person or entity is permitted to register. It was originally intended for use by domains pointing to a distributed network of computers, or "Umbrella" sites that act as a portal to a set of smaller websites.

  • .edu – education − This TLD is limited to specific higher educational institutions such as, but not limited to, trade schools and universities.

  • .mil – military − The .mil TLD is limited to use by the United States military.

  • .arpa – Address and routing − It is for Advanced Research Projects Agency in the early days on the Internet, .arpa is now exclusively used as an Internet infrastructure TLD.

In the next chapter, we will understand how to register a domain name.

Domain Name Registration

To register a domain name involves registering the name you want with an organization called ICANN through a domain name registrar. For example, if you choose a name like "", you should go to a registrar, pay a registration fee that costs around 10 USD per year for that name. That will give you the right to the domain name for a year. You should renew it annually for the same amount per annum.

Some webhosts will register your domain name for free, if you purchase a hosting plan from them, while others will do it for you as well, but you will must foot the registrar fees and charges.

Some of the biggest registrars where you can register your domain are given below −

Now, let us see step by step how to register a domain name at GoDaddy.

Firstly, we should choose our domain name and see if it is free for purchase.


In my case, I wrote “ “and clicked “Search Domain”.

Search Domain

As you can see in the results that are in the following screenshot, this domain is already taken and it is not free. Then GoDaddy will recommend me other similar names, which we might be interested in.

Similar Meaning

We will select another domain name that GoDaddy suggested us, which is “”.

  • Click on the green “Select” button.
  • Then click on “Continue to Card” as shown in the screenshot given below.

Continue Cart

On the other page, GoDaddy will ask if I want to hide my personal information from the internet for an extra fee with regards to this domain name, because by default they are open to public.

Make it Private

GoDaddy is an accepted Domain name registrar. It is also a Hosting provider which offers you hosting services for your website. It allows you to purchase and at the same time gives a suitable plan for your website.


Click “Continue to Cart”.


In the webpage that opens next, you must choose the number of years for your domain that it will be required with the possibility to extend this period.

  • Also, you have the possibility to buy other similar domains.
  • Click “Proceed to Checkout”.


As we are a new customer, we will click on “Continue”.

New Customer

In the Billing Section, we should fill genuine data because it should match with the payment information.

Billing Section

In the account information, we will enter an email id (we will get all the billing related and other notifications to this email address), username, password and PIN (this email id is also important for account resetting or other ownership issues, if the account gets hacked).

Account Information

Now, we should enter the credit card details or PayPal details. Then click “Continue” as shown in the following screenshot.

Card Details

The following screen will show up once the purchase of the domain is successful.

Purchase Domain

Website Development - Subdomains

Subdomains are extensions of domain name that you can forward to URLs or point to IP addresses and directories within the hosting account or different servers. Sub domains function separately from your main domain. We can create areas of a website by using subdomains.

Website Development - Domain Privacy

Internet Corporation for Assigned Names and Numbers (ICANN) broadly requires that the mailing address, phone number and e-mail address of those owning and administrating a domain name should be made publicly available through the "WHOIS" directories. But this rule enables spammers, direct marketers, identity thieves or other attackers to use the directory for personal information. Although ICANN has been exploring changing WHOIS to enable greater privacy. There is a lack of consensus among major stakeholders as to what type of change should be made. However, with the offer of private registration from many registrars, some of the risk has been mitigated.

There are four contact positions in a domain's WHOIS record, which are −

  • Owner
  • Administrator
  • Billing and
  • Technical

Some registrars will not shield the owner organization name to protect the ownership of the domain name.

Let us now have a detailed stepwise understanding of what is being discussed here.

Go to the URL and then enter the domain name of which we want to see the public data.

ICANN Whois Page

The next step is to click on “Lookup” as shown in the following screenshot.

Look Up

Enter the Captcha that is displayed on the webpage as shown in the following screenshot, then click on “Lookup”.


The information that this domain name has will be shown as follows. The main section is “Contact Information” which has some subsections like −

  • Registrant Contact
  • Admin Contact
  • Tech Contact

Each of these sections have −

Name and Surname, Company name, Address, Phone Number and email address. The following screenshot shows the registrant name which in this case is, LLC

Registrar Name

The following screenshot shows the information of when the domain name was registered and when it will expire.

Important Dates

While the last screenshot will show the name servers (DNS) of the domain.

Configure DNS Record on a Hosting Platform

DNS records are mainly used to convert domain names into servers’ IP that host this website. It is important to mention that the records are entered at domain registrars. They generally provide you with a DNS manager panel. The main purpose is that people and applications don’t have to remember big numbers to navigate to a domain. For example, has an IP of, so it is easier to remember a friendly name.

Pointing a Domain to an IP is done through a record. For example: A

There are other types of DNS records that are used for a webpage, depending on the functions that we need to publish.

S.No Type of Record & Explanations

A Record

Connects an IP Address to a host name


CNAME Record

Allows more than one DNS name for a host


MX Record

Ensures email is delivered to the right location


NS Record

Contains the name server info


TXT Record

Provides additional info about a host or more technical info to servers


SRV Record

Finds computers that host specific services


AAAA Record

Provides IP addresses that do not fit a standard A Record format


SPF Record

Used to help prevent against spam

Let us now see it practically: earlier the domain was purchased at GoDaddy, which needs to now point to an IP. For doing this, we must follow the steps given below.

To begin with, you should start with entering the username and password. Then click on “Manage My Domains”.

Manage Domains

Select the Domain whose DNS should be managed by clicking on Setting. Click on “Manage DNS “.

Manage DNS

A new window will pop up and you must then select the record that you want to enter. In this case, we should enter A Record to publish on the website.

A Record

The boxes shown in the following screenshot will be opened. In the “Host” box, enter the subdomain name which will be www and in the “Points to” box enter the IP – In the “TTL” drop box, we need to select 1 Hour, which means in one hour the record will be spread globally and the webpage will be effective. Once all this is done, click “Save”.

Website Development - CMS Platforms

In this chapter, we will first discuss how to make the right choice for your website and which Content Management System (CMS) Platform to choose for your website.

Choosing the Right Website

Let us understand this by asking ourselves a few questions and then discuss the concept in detail.

Question 1 − How much money do we want to spend?

Answer − This is one of the main questions because it is directly related to the budget. If your budget is low, then you should think of something non-commercial and not too complicated.

Question 2 − How much time do we have to plan for the maintenance?

Answer − If you are going to publish many offers, having a blog to moderate, etc., then for sure you will need a dynamic website. You must have extra staff for handling all this, thus this question correlates with the Question 1. Otherwise you should have a flat website, which we will explain in the following chapters.

Question 3 − Will the website be used as an e-commerce site for selling products online?

Answer − If this is the case, you should look for a platform which is called e-commerce. There are many such open source and commercial ones such as Magento, Opencard, Shopify, etc.

Question 4 − Should the view be adaptable for different screens like mobiles?

Answer − If this is one of the main criteria and if there are not many other changes in terms of information in the website; then you should go with a flat website having features like Bootstrap.

Question 5 − Will my website interact with social media or other third party platforms?

Answer − You will need a record for all the events happening on your website and they will be saved in a database. For keeping all this data and records, you will need a dynamic website.

Question 6 − What type of web programing language or platform is easier to find?

Answer − Depending on the country, there are several programing languages or platforms which are more popular than the others. So, you should first find a platform that goes with the trends of your region.

CMS Platform

Content Management System (CMS) Platforms are applications which allow to create and run your website. You will get an Admin Panel, which is an interface where you can create and update pages, posts and other type of content (images, videos, etc.) and arrange the content the way you need.

You will also be able to change the design of the site through the admin panel by installing themes (design templates) and changing them. All the actions are done simply by clicking on various buttons. You don’t have to write codes or scripts in most cases, so you can manage your content easily.

The most prominent CMS platforms are WordPress, Joomla and Drupal. They are free and open source CMS engines. That means their source code is open to the public. You can use, edit and customize the core files of the engine on your site and if you discover a great way to improve the platform, you can pitch it to the developers and help in making their engine even better in their next update.

WordPress is an open source CMS. More than 50 % of the webpages are by that platform. It is getting more comprehensive, intuitive and popular with each new update release. WordPress has a committed community, which has tonnes of free extensions and the easiest-to-use interface.

Managing your content with WordPress is perfectly simple: you create a page, add it to the menu, post something on it and see your content on the front-end of your site. All that adds up to a pre-eminent CMS platform. The official webpage is

The following screenshot shows the dashboard background.


Joomla has balance between customization possibilities and user-friendliness, yet it is much more complex than WordPress. If you have never worked with this engine before, you will need some time to get used to modifying it. Assigning plugins to modules, positioning modules on different pages, configuring layouts and other necessary manipulations can be a bit hard on a beginner developer.

On the other hand, Joomla extension developers and community have come up with many inspired solutions for common web design problems that are hard to resolve within WordPress. If we take any Joomla slider extension as an example, you can set its location on the page, the duration for showing each slide, the sliding effect and the type of pagination.

Its official webpage is


Drupal is for huge websites and organizations that can afford full-time administrators. You can do almost anything with Drupal. I am often fascinated by how many options the engine contains out of the box. Lots of things which in WordPress or Joomla would require custom coding have readymade solutions by default in Drupal. It can be enhanced even more with third-party extensions. But, I will be honest with you - learning to operate it, is the real challenge. It takes a lot of work and patience to master.

Its official website is A view of its dashboard background is shown in the screenshot below.


Flat & Dynamic Webpages

A Static or Flat Webpage means a webpage in which all the information and material is presented in front of the users as it is stored in it. A Static Webpage shows the same information and data to all users. In internet technology, Hyper Text Markup Language (HTML) was the first language or channel by which people started to create static web pages. HTML offers the style of text, paragraphs creation and line breaks. But the most important function and feature of HTML is link creation option. Static webpages are useful for their material and content, which rarely need to be revised or updated.

Advantages of Static Websites

  • Quick to develop
  • Cheap to develop
  • No need to have a big hosting plan

Disadvantages of static websites

  • Requires web development expertise to update site
  • Site not that useful for the user
  • Content can get stagnant

Web Server

The file structure of the static website with one page is as shown below.

Static Website

Dynamic Webpages

Dynamic Webpages is the latest trend at present because they can produce different content for different visitors from the same source code file. The website can display different content based on parameters like −

  • What operating system or browser the visitor is using.
  • Whether the user is using a computer or a mobile device.
  • The source location that referred the visitor.
  • If the visitor has done a purchase before from an online shop, etc.

Dynamic webpages can have a variety of purposes. For example, websites run by content management systems allow a single source code file to load the content in many different possible pages. We should mention that all these dynamic webpages use databases. Content creators use a gateway page to submit the material for new pages into the CMS' database. The dynamic page loads the material for any page in the database, which is based on the parameters in the URL. This is done when a visitor requests for a webpage. Dynamic pages let users log into websites to see personalized content.

All Content Management Systems (WordPress, Joomla and Drupal) that we mentioned before are dynamic websites.

The following illustration shows a schematic view of a dynamic webpage.

Publishing & Development Tools

As you now know the fundamental necessities for developing a website as a beginner developer, you will need some tools that you should have for primary usage.

Firstly, you should have a basic package of internet that has a good upload speed, minimally 1Mbps. Secondly, you should have a computer with any Operating System (it can be Linux, iOS X or Windows). Then the hardware specifications should be minimum – 1-2 GB RAM, Processor should be at least a Dual-Core one and the hard disk must be around 80 GB.

The next step is – you should have a text editor that will help you for code writing and editing. Some of the best text editors for this purpose are as mentioned below.

Text Sublime

Text sublime can be downloaded from It is good because the text changes the color of the parameters depending on their functions.



Another popular text editor is Notepad ++ that can be downloaded from –



The next one in the list of most popular text editors is EditPad, which is another free tool. It can be downloaded from –


Note − You should always use a text editor that you feel more comfortable working on.


Another tool that you need to have in your computer when you are specially developing a dynamic webpage is – XAMPP for Windows OS and LAMPP for Linux OS. It has various products such as

  • Web Apache
  • MariaDB with phpMyAdmin for DB Management
  • PHP and
  • Perl Extra.

If you want, you can also create an FTP Server and Mail Server with Mercury.

XAMPP Windows

Another similar tool like XAMPP is WAMPSERVER, which can be downloaded from the following link –

WAMP Server

For developers who want to code ASP should have Visual Studio provided by Microsoft. It can be downloaded from –

ASP Code

If you are a beginner and you are planning to develop a flat (static) website, you should have Visual HTML text editors called WYSIWYG. One of the most commonly used editor is Macromedia Dreamweaver. It can be easily downloaded from the following link –


The other tool that you need to have is FTP Client, which is used to transfer files to the Hosting Container. Generally, these FTP Clients are free and can be easily downloaded from the internet.

Commercial & Free Themes

A theme is a personalized design of a website often including its layout. Changing your theme, changes the view of how your website looks on the front-end. Usually CMS platforms have both free and commercial versions. These themes are categorized as per their functions like

  • Business
  • IT industry
  • Hosting, etc.

Free themes are found in theme providers and they are free of charge, but sometimes the features are more limited than that of the commercial ones. Let us take the free WordPress themes as an example. These themes are found on the following link –, you can find and install them as per your business profile or needs.

On the contrary, for the commercial themes, you must pay. WordPress commercial themes are found on the following link –

Commercial Theme

Choosing a Web Hosting Company & a Plan

When choosing a Web hosting company one of the main key indicators is to see their client’s satisfactory reviews and the price which is also important. As technologies and hosting industry changes too often and fast for an expert, we should be aware to check with following criteria’s.

  • Server Reliability / Uptime Scores – The most important point to know here is whether they have a 24×7 operating web host. You need a web host to operate on a powerful server and have stable network connections. Close to 99.5% and above is the recommended uptime score; anything below 99% is unacceptable.

  • A company that supports Multiple Add-on Domains.

  • Price of Hosting Signup and Renewal Cost. Hosting deals and shared hosting especially are normally selling very cheap on signup prices, but charge much higher on renewals.

  • What Refund Policy they are offering? – If you choose to cancel your host within the trial period, what are the implications? Does the company provides a full money refund? What is the hosting company’s refund policy after the trial session? Are there any cancellation charges?

  • Easy to use Hosting Control Panel. A user-friendly and functional hosting control panel is very important.

  • Account Suspension – What are the limitations? Here’s a money tip that most hosting review sites will not tell you – Hosting companies will pull the plug and suspend your account if you are using too much CPU power (yes, unlimited hosting is limited) or violating the rules.

  • Do they offer Backup. Are they free of charge?

  • Do they have 24/7/365 Live Chat Support.

Choose a Web Hosting Plan

Before choosing the right hosting plan, you should know what you need, a Windows OS based hosting or a Linux OS based hosting. This choice depends on the coding language that your website has. If it is ASP, it should certainly be a Windows based hosting and should also have an IIS server installed in it. If it has any other programming languages like PHP, Perl, Ruby, then you should go with Linux based hosting.

After you have decided on the type of hosting (Windows or Linux), you should define the right hosting plan.

You should take into consideration the following factors −

  • Disk Space
  • Bandwidth
  • Number of Hosted Domains
  • Number of Subdomains
  • Parked Domains
  • Versions of PHP, MySQL and Perl.

The main plans in general are as follows −

Shared Hosting

It is the most basic plan that every hosting provider offers. Shared hosting is fundamentally many hosting accounts located on one server. Some of them share the same IP address (although a dedicated IP address is often available for an additional fee). This plan will always offer a specific set of features and will always have resource limits. If you are not certain, then it will be better to start with a limited plan and later upgrade it after the website grows and gets more traffic.

VPS Hosting

VPS is a Virtual Private Server. This refers to the partitioning of a physical server into multiple servers where each one acts just like a dedicated server, each has its own operating system and can be rebooted separately. These operating systems receive a specific share of the resources of the physical server and they are isolated from each other. There are two types of VPS hosting −

  • Managed − Managed means that the patching is done by the hosting company by offering a CPanel in it.

  • Unmanaged − Unmanaged is a hosting where you should take care of your VPS in everything and there is no CPanel in it.

Dedicated Hosting

This is the most powerful type of hosting, which meets the requirements and needs of big businesses. Dedicated server owners can sell hosting services for a profit. They can choose the server specifications and environment. If you have heavy traffic, a very popular site, or a large customer database, then consider Dedicated Hosting. A dedicated server also provides more freedom to send emails and stream media.

TIPS − The most important thing in hosting is to check prices of different Hosting Companies and their hosting plans prices with comparison websites for a better understanding. An example of a comparison website for checking prices of hosting companies is –

Hosting Plans

Website Development - Cpanel

Control panel is the administration web interface of your webhosting account. It is an interface that you access to administer all the aspects of your account. You can typically control all portions of your site within the control panel without using any additional software like FTP software to upload files, though many people find it faster and easier to do so.

Some web hosts use customized, proprietary control panels, but most of them use popular platforms. However, the leader of the industry is cPanel. It is the most spread out control panel among the hosting providers. The official webpage of cPanel is –

Now let us discuss cPanel in detail and understand the most important aspects of it.

Firstly, to enter the CPanel you should type in the URL which the Hosting Company will give to you. This in general should be – You should then enter your username and password which the hosting company has given you.


The main dashboard will be as shown in the following screenshot, where on the left-hand side, you will see the General Information, which will show the username, domain name, home directory and the IP address of the log in. On the left towards the bottom of the screen are the Statistics like databases used, email and the add-on Domains.

Main Dashboard

In the FILES section, the most important folder is of the File Manager, you can upload or download files of your webpage. The next important is FTP Accounts, where you can create users that can use programs like FileZilla to upload or download files.


Taking a backup of the FILES section allows you to fully or partially download the webpage.

Back Up

In the DATABASES, the phpMyAdmin is the most important section which allows you to manage the database of the webpages. It can edit, add, truncate databases and tables. The MySQL Databases allows you to create and delete the databases or users. The same thing can be done step by step with the MySQL Database Wizard.

PHP Admin

In the DOMAINS section, the Addon Domains folder is an additional domain that the system stores as a subdomain of your main site.
