The term domain name has multiple meanings, all related to the:
Main article: Domain name system
- a name that is entered into a computer (e.g. as part of a Web site or other URL, or an e-mail address) and then looked up in the global Domain Name System which informs the computer of the IP address(es) with that name.
the product that registrars provide to their customers.
- a name looked up in the DNS for other purposes.
They are sometimes colloquially (and incorrectly) referred to by marketers as "Web addresses".
The authoritative definition is that given in the RFCs that define the DNS.
Domain names are hostnames that provide more easily memorable names to stand in for numeric IP addresses. They allow for any service to move to a different location in the topology of the Internet (or another internet), which would then have a different IP address.
Translating numeric addresses to alphabetical ones, domain names allow Internet users to localize and visit Web sites. Additionally since more than one IP address can be assigned to a domain name, and more than one domain name assigned to an IP address, one server can have multiple roles, and one role can be spread among multiple servers. One IP address can even be assigned to several servers, such as with anycast and hijacked IP space.
The following example illustrates the difference between a URL (Uniform Resource Locator) and a domain name:
URL: http://www.example.com/
Domain name: example.com .
Every domain name ends in a top-level domain (TLD) name, which is always either one of a small list of generic names (three or more characters), or a two characters territory code based on ISO-3166 (there are few exceptions and new codes are integrated case by case). Top-level domains are sometimes also called first-level domains.
Exaples of top level domains: .com, .net, .org, .travel, .mobi, .eu, .info, .biz, .aero and so on...
If you have a webpage or plan on starting a website, the questions often asked are: What is the best web hosting provider? Where should I host my website? Key factors are reliability, uptime, support, reputation, and price.Many of those came and went. Yahoo purchased one of these business and built their web hosting business around it.
Yahoo web hosting for small businesses provides the kind of long-term stability and reliability that you need. They offer a number of hosting packages, ranging from $9 to $39. We summarize them below: Yahoo Web Hosting Starter Package

At a meeting on 21 March 2005, the board of ICANN approved the delegation of the new .EU top level domain and authorised their CEO, to enter into an agreement with EURid, the organisation selected by the European Commission to operate the .EU registry. The decision was taken following contractual negotiations between ICANN and EURid over the past few months and approval of the agreement by the European Commission.
All applicants for register a .eu domain name, should meet one of the following eligibility criteria:

Yahoo Inc. will make available to subscribers of its Web hosting services the open-source WordPress blog publishing software, both organizations are announcing on Tuesday.
The deal is similar to one Yahoo struck last week with Six Apart Ltd., maker of Moveable Type, and is intended to broaden the blogging software options accessible to individuals and companies that use Yahoo to host their Web sites.
Like Moveable Type, WordPress will be a free option to all new and existing Yahoo Web hosting subscribers, starting with the most basic plan that costs US $11.95 per month.
"We`re committed to working with industry leaders to provide top-notch publishing platforms," said Guy Yalif, Yahoo`s director of Web hosting products.
Installing and maintaining WordPress via the Yahoo service will require just a few clicks, and thus will be much simpler and quicker than if users do it manually, said Matt Mullenweg, WordPress founding developer.
The spam and scam watchdog Spamhaus has accused online internet services giant of hosting almost 5000 websites with phishing related content.
Many of the websites have obvious names which point to nefarious content including "bank", "eBay" and "PayPal."
News of Yahoo`s safe harbour for phishing websites is likely to cause embarrassment and Spamhaus has cited a lack of staff dedicated to online security matters at Yahoo as a principal reason behind the huge criminal presence.
US ISPs and web hosting companies are notorious reluctant to shut down websites, even after alledged phishing efforts due to possible legal repercussions related to putting websites out of business and it appears many of the Yahoo hosted phishing websites are registered in the USA.
Have you ever wanted to create your own Web page, complete with titles and text and graphic icons? Have you ever heard the word "HTML" and wondered what it means? If so, then read on...
In this post, I will look at the art and science of Web pages and experiment with a number of techniques that you can try out on your own machine today. We`ve even created a tool that lets you try out HTML and view it instantly. As it turns out, Web page creation is both incredibly easy and a lot of fun, and totally within your reach. By the time you finish reading this article, you will be ready to start assembling your own!
Creating great Web pages is easier -- and cheaper -- than many people realize. You need the right software and a little practice. Curious? to look at Web tools.
Web page - A Web page is a simple text file that contains not only text, but also a set of HTML tags that describe how the text should be formatted when a browser displays it on the screen. The tags are simple instructions that tell the Web browser how the page should look when it is displayed. The tags tell the browser to do things like change the font size or color, or arrange things in columns. The Web browser interprets these tags to decide how to format the text onto the screen.
Web server - A Web server is a piece of computer software that can respond to a browser`s request for a page, and deliver the page to the Web browser through the Internet. You can think of a Web server as an apartment complex, with each apartment housing someone`s Web page. In order to store your page in the complex, you need to pay rent on the space. Pages that live in this complex can be displayed to and viewed by anyone all over the world.
A product created by Allaire Corporation of Cambridge, Mass. (in 2001, Allaire merged with Macromedia) that includes a server and a development toolset designed to integrate databases and Web pages. With Cold Fusion, a user could enter a zip code on a Web page, and the server would query a database for information on the nearest movie theaters and present the results in HTML form. Cold Fusion Web pages include tags written in Cold Fusion Markup Language (CFML) that simplify integration with databases and avoid the use of more complex languages like C++ to create translating programs.
PHP is currently one of the most widely use scripint technology on the internet. PHP is a hypertext preprocessor, used on the server-side used to create dynamic Web pages. PHP can perform almost any task that any ASP, JSP, Cold Fusion or CGI program can do, but its strength lies in its ease of use and compatibility with the powerful Mysql database. Below are a few web hosting companies that offer good PHP and Mysql web hosting services.
If you've ever been curious about the process, or have ever wanted to know some of the specific mechanisms that allow you to surf the Internet, then read on. In this article, you will learn how Web servers bring pages into your home, school or office. Let's get started!
The Basic Process
Let's say that you are sitting at your computer, surfing the Web, and you get a call from a friend who says, "I just read a great article! Type in this URL and check it out. It's at http://computer.com/web-server.htm." So you type that URL into your browser and press return. And magically, no matter where in the world that URL lives, the page pops up on your screen.
At the most basic level possible, the following diagram shows the steps that brought that page to your screen:
Your browser formed a connection to a Web server, requested a page and received it.
Behind the Scenes
If you want to get into a bit more detail on the process of getting a Web page onto your computer screen, here are the basic steps that occurred behind the scenes:
The browser broke the URL into three parts:
The protocol ("http")
The server name ("www.e-blogs.com")
The file name ("web-server.htm")
The browser communicated with a name server to translate the server name "www.howstuffworks.com" link to www.howstuffworks.com into an IP Address, which it uses to connect to the server machine.
The browser then formed a connection to the server at that IP address on port 80. (We'll discuss ports later in this article.)
Following the HTTP protocol, the browser sent a GET request to the server, asking for the file "http://computer.howstuffworks.com/web-server.htm." (Note that cookies may be sent from browser to server with the GET request -- see How Internet Cookies Work for details.)
The server then sent the HTML text for the Web page to the browser. (Cookies may also be sent from server to browser in the header for the page.)
The browser read the HTML tags and formatted the page onto your screen.
If you've never explored this process before, that's a lot of new vocabulary. To understand this whole process in detail, you need to learn about IP addresses, ports, protocols... The following sections will lead you through a complete explanation.
The Internet
So what is "the Internet"? The Internet is a gigantic collection of millions of computers, all linked together on a computer network. The network allows all of the computers to communicate with one another. A home computer may be linked to the Internet using a phone-line modem, DSL or cable modem that talks to an Internet service provider (ISP). A computer in a business or university will usually have a network interface card (NIC) that directly connects it to a local area network (LAN) inside the business. The business can then connect its LAN to an ISP using a high-speed phone line like a T1 line. A T1 line can handle approximately 1.5 million bits per second, while a normal phone line using a modem can typically handle 30,000 to 50,000 bits per second.
ISPs then connect to larger ISPs, and the largest ISPs maintain fiber-optic "backbones" for an entire nation or region. Backbones around the world are connected through fiber-optic lines, undersea cables or satellite links (see An Atlas of Cyberspaces for some interesting backbone maps). In this way, every computer on the Internet is connected to every other computer on the Internet.
