What is domain name? - Intro to Domain Name

What is domain name?

If you are new to IT, you probably heard about "domain name" and you might be questioning yourself "What is a domain name ?". Well before we dive deeper into answering the question "what is a domain name? " , let us first clear our self with some basics on "what is a domain name? " then we could dive deeper into defining Domain names, Their types, TLD's, How to register domain name and much more beyond if you keep on reading.

Basics on What is a Domain name?

A domain name in general is the name a website has. But in earlier days of internet websites did not had names and where not always live. In earlier days you need to remember a long digits of numbers to visit a website. like is the server IP address of a website. Just think how hard it would be remember a website if you did not note down it's IP address. This really made internet an ugly and tough thing for visitors. I mean how could a visitor remember the big numerical digit if he wants to visit Facebook or Google. For computers it is more than fine to remember big numerical digits because they operate on binary system but what about us "can we really type the big numerical digit on our web browser each time we want to visit a website?".

Simply no, this was the only reasons why the need of domain naming system arrived and one can say that this Domain name invention proved revolutionary to internet. Now people could visit Facebook without necessarily remembering the numeric terms i.e. IP address.
Since we now have domain name system, it is helping both the visitor and the machines at the same time. Now users don't have to type the big numeric terms and computers can still very effectively relate the user query and so them the relevant results by patching the domain names with the server IP of the website. so it sounds more user as well as computer friendly and this makes internet a better place to visit.

Although domain names are simply patched with numeric terms known as IP address but that's not all a domain name consists of. An IP address is there on a domain name to point out the server location of a website but they usually do not make up all of it, like what we see in an IP address.

What is Domain Name format ?

Above we have discussed some basics on what is domain name ?, it's need, evolution etc. It's time to dive deeper into what is domain name?, how is it named, It's format etc.

A domain name has 4 parts:
  1. URL of the domain name.
  2. The "WWW" of the domain name
  3. The body of the domain name

The extension of the domain nameThe 1st part of the domain name:

URL is the very first part a domain has. URL is an acronym for Uniform resource locator. The function of URL in a domain name is to instruct the web browser to point a domain name where.i.e. It's is usually found "http://" in a domain name which instruct the web browser to point a hypertext document usually "html" acronym for hyper text document. If we want to understand in simple terms usually in layman's language http:// in a URL would mean to point a webpage. In other cases it can be "https://" of even "ftp://". Ftp is acronym for file transfer protocol. A "ftp://" in domain name would suggest the web browser to transfer files. A webmaster would go for ftp in his domain name if he want to permit it's visitors to download files stored on his server, on his website.

The 2nd part of the domain name:

WWW is the Second part a domain has. WWW is acronym for world wide web. The purpose of WWW in a domain name is to tell both the visitors and bots that the domain is a web property. It is now also considered as deprecated since most of the web users no longer type WWW in a domain name. WWW is followed by the actual name of a website.

The 3rd part of the domain name:

The body of the domain name is the third and the most important part of a domain name. The body of domain name is the main remembereable part of a domain name. Users are free to decide the name of the body part. The naming could be done according to ones wish like it could be words or phrases or a combination of letters, words and phrases. The word limit of the body of the domain name is 63 letters but it is always advisable to keep it short usually withing 16 words. There are certain things a webmaster should consider while registering the domain name like shortness,easy to remember and SEO friendly for search engines.
What is the history of Domain name Registeration?

The 4th part of the domain name:

The 4th and the final portion part of a domain name is the domain name extension but what is domain name extension ?.

well, A domain name extension lets user as well as the web browser know more about the origin of a website. i.e. If a domain name ends with an extension ".com" then this specifies both web browser and the user that this website is a commercial website. Domain name ending with extension ".edu" will mean a website is for educational purpose.
.com extension is most widely used and very popular also. So it is also advisable to go for .com domain name if available. .com,.org and .net extensions are most popular and also a TLD so one should register his domain with these extensions if available. Suggesting that .com,.org and .net are most popular and should be used while registering a domain name does not mean that other extensions are bad or should not be used. Think of, Wikipedia ends with .org extension and is a very popular site. It's not the extension or name but what matters most is the content of a website.

If you want further info on what a domain name extension is?, then you must know that other than TLD's a domain extension is also based on the geographic location i.e. A country based extension e.g. ".fr" domain extension simply specifies that this website is from France ".jp" for japan. A ".in" would mean a website from India. These domain extensions can also be state wide e.g ".ca" represents the California state of America. These "domain extensions" if used wisely could prove excellent for localized marketing.
One important note here to make is that each of the domain names are seperated by a fullstop(.) mark.
