Whenever we use internet, we have to enter the name of website in url address bar. These names and address urls of website is a domain names. It is formed by the rules and procedures of domain name system. In other words any name register in DNS is a domain name. These domain names are register under the Registrar companies like Big rock, godaddy etc.
What is need of Domain names.?
Yes whole web world is totally depend on domain names because without domain name it not possible to serve any site. without domain we will not able to open any page or file. Suppose without domain like Google.com, Facebook.com etc how we can open it. ? If there are no defined names of web pages how server and web Protocols open that particular page or website. Many Times we find DNS error occur on our internet. This error may be because of domain name is not parked on particular web page or many other reasons.
Domain name is a particular name which point out that particular site for which that domain name is used. Every web service need domain names while it is sub-Domain or Top level Domain (TLDs) which includes and categorizes under Generic Top-level domain (gTLDs) such as .Com, .Net, .org, .info etc. and Country code Top-level Domain (ccTLDs) such as .in, .us, .it, .pk are some extensions.
For example Google.com, Facebook.com, YouTube.com are some most popular Top-level domain names.
We can also make sub-domain name of any Top-level domain name. while these sub-domain also use for many purpose of creating different web page from web page of TLD site. mostly every TLD domain use www as www.sitename.com
While if we use TLD as sub-domain is like gmail.google.com which is sub-domain of Google.com. Every domain name can make many different sub-domains.
For example if you have domain like www.mysite.com you can use this name of also in email as sub-domain of other sub-domain webpage.
Go.mysite.com , contact.mysite.com, Support.mysite.com, M.mysite.com, services.mysite.com and more as you want.
Many sites also providing users to make sub domain for there domain. Such as Blogger and WordPress are also provide users to create blog which sub-domain of there site.
As like Safe Tricks is a blog under blogger and its original sub-domain address is safetricks.blogspot.com
here safetricks is a sub-domain of blogspot but i am using my own custom domain so only custom domain is display in address bar.
You can also use redirect different domain names on particular website. Like my previous domain name is safetricks.in which i use for 5 months and then i buy Safetricks.net
Now safetricks.in and safetricks.net are different domains not same domain. Then i redirect safetricks.in towords safetricks.net.
Now both of domains are pointed on 1 site not different site and also both are working you can check it.
At last i think everyone who never think about domains after reading this article, they learn something new. To start your online business these basic things should be clear in mind. I hope you like this article and if you want give any suggestion or if you think that i am wrong at any part feel free to ask me in comment.
