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.

Copyright lawyer Everything You Need to Know about a Copyright Lawyer Everything you may need to know about a copyright lawyer before you get one, there are so many different types of lawyers a little run down never hurt anyone. Copyright lawyers deal with many different subjects such as internet law, intellectual property, patent and trademark and of course your copyright laws. Each lawyer has gone to school for some time in order to get a degree to help you, which means they know more about the law than you do. Some mistakes website owners make is when they buy articles online; many times a buyer just assumes they have full copyright. This isn?t always the case, depending what was agreed on will determine who has ownership. In order to make sure you don?t fall into this trap have a lawyer set up a contract before you hand over any money, this way you know for sure if you have full ownership or if the writer does. There are actually three different categories that you may purchase an article, usage, full and unique. A copyright lawyer will explain exactly what each one means. Usage is basically meaning the buyer gets to use the article one time, but the writer can use it again or resell it. Full rights will give the buyer all rights; they can even place their name on the article saying they wrote it. A copyright lawyer will never tell you that you don?t have to register your copyright; in fact they will encourage you to do it. Sure, they get money to do it for you but you will have documented proof that you own the copyright. If you don?t file it, you can?t sue if someone uses your information. A copyright lawyer is not cheap, that means if you are just looking to pay out a mere $300 you are looking in the wrong field. Sure there are sites that offer to do your bidding for you. Are you sure they are someone you trust? Stick with your gut feeling, pay the money and have someone there to walk you through everything you need. Most copyright lawyers will have special discounts on packages, which means you?ll be getting a lot more than what you originally walked in for. Chances are your lawyer will even advise you of things you didn?t even have knowledge about. A copyright lawyer can help you better understand the laws of the virtual world, as well as the real world. Every day someone new is getting sued over content on the internet, it can be as simple as someone stealing an article, quote, song or a picture. A big issue is using another company?s name in your tags to get the search engines to rank you higher, you will get caught and when you do the fines are pretty steep. Other issues may be with bloggers today, be careful with what you say about your places of business, not only could you get in trouble for any copyrighting issues but slander is another big issue. Another thing you may want to know about a copyright lawyer is that you can use one even if you are actually getting sued. Many people only look for one when they want to copyright something or sue someone, but they normally don?t think about hiring a copyright lawyer when they are being sued. This is definitely the person you want on the job defending you if the time comes, after all they do know their job. That?s everything you need to know about a copyright lawyer before you get one, if you have any other questions call them up and ask them. Lawyers love to give advice, especially if they think you?ll be hiring them.
