Summary, What Is A Domain Name
What is a domain name? It is a word or word sequences that are entered into the address bar of an internet navigator to visit a particular website. In simple terms, a domain name is an online identity of a web owner.
A domain name helps to translate IP addresses to words. A domain name is a name that identifies one or more IP addresses, for instance the domain name microsoft.com represents about a dozen IP addresses.
Internet is based on IP addresses, not domain names, so every Web server requires a Domain Name System (DNS) server to translate domain names into IP addresses. Domain Name System stores and associates many types of information with domain names and helps to translate domain names to IP addresses.
Internet users use domain names as the URLs, ‘Uniform Resource Locators’. Domain names are used in URLs to identify particular Web pages. Take the URL http://www.pcworld.com/index.html, in the URL pcworld.com is domain name.
Every domain name has a suffix which is termed as top level domain (TLD)
The top level domain indicates the category to which a domain name belongs to. There are a limited number of top level domains, such as .gov (government agencies), .edu (educational institutions), .org (organizations, .mil (military), .com (commercial business), .net (network organizations), .ca (Canada), .uk (United Kingdom), .de (Germany or Deutschland), .us (United States) etc.
Technically, domain names are host names. Oftentimes domain names are referred to as “web addresses” that is technically incorrect and often domain names and hostnames are used interchangeably, but there are subtle technical differences between the two.
On the Internet, a hostname is a domain name assigned to the host. It is usually a combination of the host’s local name with its parent domain’s name. For instance in URL “fr.wikipedia.org,” the host name is “fr” and the domain name is ‘wikipedia.org’. The host names are translated to IP addresses via the local hosts file, or DNS. A single may possibly have several host names. A domain name is not a host name, if it doesn’t have an IP address. Thus all hostnames are domain names, but not all domain names are hostnames.

3 Options For Hosting Multiple Websites
The prices of domain name registration and web hosting services have dropped. This makes it possible to own multiple websites without going broke. If you plan to operate multiple websites, here is some information on the different options available to you.
The first thing to consider when setting up multiple websites is whether or not to host them all with the same web hosting company. Many web hosts offer packages that let you set up multiple sites on a single account. Almost all will let you set up multiple accounts, one for each site.
If you are happy with the hosting company you’re using for your existing website(s). One advantage of using them for another site is the fact that you know they offer good service and support.
They might also offer discounts for multiple sites, so your costs might be lower if you stay with them again.
On the other hand,
If you choose a different host you’ll be able to compare the quality of another company with whomever you’re currently using. If you ever run into problems with them, you’ll have an alternative. It’s wise not to “put all your eggs in one basket” as the saying goes.
Another advantage of using a different host is that you’ll get a different IP address for each of your sites. If your sites are related to one another and you want to link them together. Having different IP addresses can sometimes help your site rank higher in the search engines.
Links from other sites are one of the most important factors in getting your site ranked highly. If those links come from sites on the same IP address, it is a signal to the search engines that they are quite likely all owned by the same person, and they may discount the value of those links.
If you do choose to host all your sites with one company, there are essentially 3 choices – separate accounts for each site, a reseller account where they are all hosted or a dedicated server, again where they are all hosted.
Separate accounts are self-explanatory, so let’s look at reseller accounts. As a reseller, you are basically acting as an agent for the hosting company. Baisically you are a middleman between them and the end user.
The idea is that you can set up your own company offering web hosting that is ultimately hosted by the company. You don’t have to resell this hosting. However you can use the hosting services for your own websites, essentially “reselling” the hosting to yourself.
A reseller account is nice because all your websites are “under one roof” and you have a single point of contact for any technical problems.
Hosting on a dedicated server gives you complete control of the computer that is the web server. You can install any software you want, any operating system you want and you can allocate resources like memory and hard disk space however you want to divide it up between your sites.
The disadvantage of a dedicated server is that you are responsible for maintaining the server and sometimes even for the technical side of things. If you aren’t familiar with the technical side of running a web server. You may need to choose a managed dedicated server, where the hosting company looks after these issues.
Dedicated server are, of course, more expensive than the other options. So unless your websites are well established, with a lot of traffic, they may not fit within your budget.
