We can install VPN Add-ons in Mozilla Browser if you don't want to install any VPN software in your computer because of different kinds of reasons. I've made a video to explain about it.
When we should use free public DNS ? Sometimes, we can't enter some websites although we can enter some websites. That may be because of DNS error of your ISP if the website is not down and your network administrator does not set any rule to block the websites. At that time, we should use free public DNS. The followings are some of free public DNS:
1. Google 8.8.8.8, 8.8.4.4
2. Norton ConnectSafe 199.85.126.10, 199.85.127.10
3. SafeDNS 195.46.39.39, 195.46.39.40
4. Verisign 64.6.64.6, 64.6.65.6
5. GreenTeam 81.216.119.11, 209.88.198.133
6. DNS.Watch 84.200.69.80, 84.200.70.40
7. Comodo Secure DNS 8.26.56.26, 8.20.247.20
I want to explain about VPN because some of my friends are confusing about VPN.
VPN is used to get secured network connection through Internet. The big companies also use VPN to get secured network connection in connecting offices, industries, etc., from different locations through the Internet. (for example, most of the banks use VPN).
Generally, there are two types of VPN.(More than two if detailed)
1. Side-to-Side VPN.
2. Remote Access VPN.
What is Server?
Server is a computer that stores data and share with its clients. There are so many server operating systems such as Ubuntu, Redhat, CentOS, Fedora, Windows, etc,. In Windows Server, there are so many versions:
1. Windows Server 2003
2. Windows Server 2008
3. Windows Server 2012
4. Windows Server 2016

Windows Server provides so many features such as DNS, DHCP, Active Directory (AD), File Sharing, Internet Information Service (IIS), Server Clustering, etc,.

Write the above codes and save it as test.html in somewhere. Try to open that file by double clicking and you will find it working.
HTML development can be done in notepad that comes along with Windows, text editors, IDE Software and WYSIWYG (What You See Is What You Get).
HTML is Hypertext Markup Language. It is a standard markup language. It describes the structure of the web page and defines the contents. It is a language should be firstly learned for those who start to learn web programming.
Example 1

<body>
<p id = "demo"></p>
<script>
const x = (x, y) => x * y;
document.getElementById("demo").innerHTML = x(8, 8);
