Web Hosting - The Internet and How It Works
In one sense, detailing the statement in the title would require at least a book. In another sense, it can't be fully explained at all, since there's no central authority that designs or implements the highly distributed entity called The Internet.
But the basics can certainly be outlined, simply and briefly. And it's in the interest of any novice web site owner to have some idea of how their tree fits into that gigantic forest, full of complex paths, that is called the Internet.
The analogy to a forest is not far off. Every computer is a single plant, sometimes a little bush sometimes a mighty tree. A percentage, to be sure, are weeds we could do without. In networking terminology, the individual plants are called 'nodes' and each one has a domain name and IP address. Connecting those nodes are paths.
The Internet, taken in total, is just the collection of all those plants and the pieces that allow for their interconnections - all the nodes and the paths between them.
Servers and clients (desktop computers, laptops, PDAs, cell phones and more) make up the most visible parts of the Internet. They store information and programs that make the data accessible. But behind the scenes there are vitally important components - both hardware and software - that make the entire mesh possible and useful.
Though there's no single central authority, database, or computer that creates the World Wide Web, it's nonetheless true that not all computers are equal. There is a hierarchy. That hierarchy starts with a tree with many branches: the domain system.
Designators like .com, .net, .org, and so forth are familiar to everyone now. Those basic names are stored inside a relatively small number of specialized systems maintained by a few non-profit organizations. They form something called the TLD, the Top Level Domains. From there, company networks and others form what are called the Second Level Domains, such as Microsoft.com.
That's further sub-divided into www.Microsoft.com which is, technically, a sub-domain but is sometimes mis-named 'a host' or a domain. A host is the name for one specific computer. That host name may or may not be, for example, 'www' and usually isn't. The domain is the name without the 'www' in front. Finally, at the bottom of the pyramid, are the individual hosts (usually servers) that provide actual information and the means to share it.
Those hosts (along with other hardware and software that enable communication, such as routers) form a network. The set of all those networks taken together is the physical aspect of the Internet.
There are less obvious aspects, too, that are essential. When you click on a URL (Uniform Resource Locator, such as http://www.microsoft.com) on a web page, your browser sends a request through the Internet to connect and get data. That request, and the data that is returned from the request, is divided up into packets (chunks of data wrapped in routing and control information).
That's one of the reasons you will often see your web page getting painted on the screen one section at a time. When the packets take too long to get where they're supposed to go, that's a 'timeout'. Suppose you request a set of names that are stored in a database. Those names, let's suppose get stored in order. But the packets they get shoved into for delivery can arrive at your computer in any order. They're then reassembled and displayed.
All those packets can be directed to the proper place because they're associated with a specified IP address, a numeric identifier that designates a host (a computer that 'hosts' data). But those numbers are hard to remember and work with, so names are layered on top, the so-called domain names we started out discussing.
Imagine the postal system (the Internet). Each home (domain name) has an address (IP address). Those who live in them (programs) send and receive letters (packets). The letters contain news (database data, email messages, images) that's of interest to the residents.
The Internet is very much the same.

Web Hosting - All About Domain Names "What's in a name?" Shakespeare asks in Romeo and Juliet. In the case of your web site the answer is: quite a lot. A domain name is the English (or other) language designator for your site. Because of the way the Internet functions, that name is associated with an IP address, a numeric identifier that computers and network components use to connect a browser to a web site. It's not mandatory that a site has a name. But directing visitors by IP address can quickly generate difficulties. Having an IP address IS mandatory, since it's ultimately the way a web site is located by other computers and network software. In the early days of the Internet the name was chosen carefully in order to help a person remember the URL. That made it easier to type, too. With hotspots on a page, great search engines, social networking and other contemporary tools, that's not as important now. But from a marketing perspective, it still helps to have a good name. It's still beneficial to have a site called 'CheapTVs.com' if what you sell are inexpensive TV sets. Calling your site, 'InexpensiveElectronicVisualDisplayDevices.com' may describe your business in some way, but it's a little harder to refer a new person to your site. Which name you choose can, therefore, affect how much traffic your site gets, how soon. Sooner or later, if you have information and/or products/services that people want, word will get around. But having a good name can certainly help. Love them or hate them, the Google company chose well. Of course, the fact is that there are millions of web sites around the world. That means, you don't necessarily get the name of your first choice. ICANN (Internet Corporation for Assigned Names and Numbers) is the internationally recognized authority for managing IP addresses across the worldwide Internet, along with the top-level domain name-parts (.com, .net, .org, .edu, and so forth). But registering a name is done by simply contacting any of a hundred organizations that work as intermediaries to establish and track the names. GoDaddy, Register.com, Network Solutions and a great many others provide the service for anywhere from free to a few dollars per month or year. You contact them by navigating to their web site. Then, using a feature they all provide, you can select a possible name. They use something called whois and other software to determine if the name is already claimed. Or, you can check yourself at www.whois.com. Registration is for a limited time, but typically renewable in perpetuity provided you pay the (usually annual) fee. You may have to go through several choices to find a domain name that isn't already in use. With so many millions of sites, the odds of you getting your first choice is slim, unless you have a highly unusual imagination. But, it's also true that domains tend to die or expire. As they do, the name becomes available for use by someone new. A method for getting on a 'waiting list' is available. You register the name you want and if and when the name becomes available, you are offered the chance to claim it. Naturally, there's competition even on the waiting list for 'good' names. There are many different ways of establishing priority that vary by company. At any given time there are thousands of so-called auctions going on to bid on names. Give some thought to your new domain name and research its availability, but don't stress over it. The name isn't everything. After all, if Google had built a search engine that delivered usable results only 10% of the time, their name would be mud.
