What is a domain name and why would I want a?

In this article we will cover which is a domain name, how they work and why you need the basics in at least one. I will try and avoid complicated computer terms and stick to statements that science should be easily understood level by a person without a computer.
What is a domain name? Before we can go, in which a domain name is, I'll tell you why we need them, such as the responses that complement each other. The Internet is just a really great collection of connected computers (or network). For domain names that you have can think of each computer on the Internet on the Internet a bit like the phone system and how the phone system to explain her own cell phone addresses unless an Internet telephone number called an IP number. This address consists up to 12 digits in the form of 123.123.123.123, computers use these IP addresses to send information with each other over the Internet.
If the Internet it quickly was created, it became clear that these IP addresses were not easy to remember and a different method was need to this make addresses human friendly. The solution to this was the domain name system (DNS). DNS is basically a really, really big phone book for computer. If you enter a website address in your Web browser it checks the DNS for this Web site name and finds the IP address. As soon as it can then send a message to this computer and issues for the Web page that the IP has you.
OK, so you know that a domain name is a Web site address, but which part of? To view site addresses, so we can identify and discuss, which bit of it is a domain name.
http://www.itxcel.com/index.html
The above address is the home page of the website ItXcel. It can be divided into 3 main areas. The first part is http:// only your Web browser what information that need to get and how it causes is. The last part is / this is the name of the files on the remote computer that you want to get your browser to index.html. The bit in the middle www.itxcel.com is a domain name. This is the name that sends your computer to the DNS, the IP address again.
So you will know what is a domain name, and that it called a phone book change DNS your easy to remember domain name to an IP address that can understand computer. The Internet telephone directory (DNS) is something special, that everyone on the Internet needs to use it. This makes the DNS very very large (100 + million addresses) large. Due to the size of this phone book that needed it, have a carefully organized and managed structure.
Domain name itself are divided into different levels as a hierarchy. The DNS system uses to locate this hierarchy of DNS for the IP address of domain name which they tried to find. The last bit of a domain in the previous example, the com part is called the top level domain. There are a wide range of top level domains as com, net, org, and information. There are also very similar to endings country level domains like UK and de called. Each of the top level and country level domains are managed by a different organization, sometimes companies or non-profit organizations and sometimes Governments are. In the domain, these organizations are referred to as the register. Each registration is looking for own domain name system belongs.
If you decide to use a domain name in the top level domain to com, such as mycompany.com you would have this name from the registry that assigned this top level domain (for a US company called VeriSign .com) managed. The process of assigning a domain name is a domain registration.
Domain registration is more like a lease than a purchase. You are the relation second levels (the Mycompany bit) VeriSign for a certain amount of time typically rent from 1 to 10 years at a time. A second level domain register most organizations, that allow you to charge one for every year you register for the domain. With almost all domain name get you also have the option to renew your registration (rentals), if it is close to (expiring) to an end.
Once you have registered a second-level domain, you will be so many third level domains (sometimes called subdomains) how you want to create. In our previous example, the www is a subdomain of itxcel.com.
Most of the register that name manage this top level domain not individuals or company domains to register directly with them. Domain register, that you a company like ItXcel must use. We act as Registrar and send all the necessary information and the application fee in the registry. Registrars in each of the registers of the customer useful, since they are the differences, and offer a simple two-step process hide for the registration of a domain. Registrar you can manage and monitor all domains for from one place, rather than with another company for each top-level domain.
OK so I know which one is a domain name, why do need one? You can picture what it would be a nightmare you had an email address such as myname@123.246.128.255 or a website address [http://123.246.128.255/?]
These addresses are possible but not very easy to remember. Now, if you register a domain name you can create as an email address such as MeinName@meinefirma.de and a Web site address such as mycompany.com. These are easier to remember and professional look like 100 times.
One of the important points to register a domain, once done you have to an exclusive right which use for that domain, as long as you the domain keep registered in your name. If you renew a domain at the end of the registration period, it will become again free for registration by another person. For this reason, if you do not want or need a website at the moment, it is also still a good idea, as soon as possible to register a domain. Imagine if your competition registered the domain name of your company or product. Although exists, this domain is get a process it can be long and complicated. It is definitely easier to save a little money to your chosen domain name front.
