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 music Copyright Music in Order to Protect Future Profits If you are a budding artist seeking to copyright music that you have labored over, there is good news. Many people confuse copyrighting music with registering music and they are two different things. According to the law in the United States, once you have written or recorded your music in a permanent form, it is copyrighted. Of course, it might help to first understand what it means to copyright music in the first place. A copyright is a certain legal protection that is offered to those who compose creative works. Whether those works be art, music, or the written word. According to the U. S. constitution there are limits that can be placed on the amount of time that the work is exclusively protected. If you copyright music, this means that you and you alone have the right to use your work or allow others to use your work. You also have the right to distribute copies of your work. Whether those copies are in the form of written or sheet music or recorded music to the public as well as the right to perform your music for the public. There is something called fair use that despite your copyright; music written or recorded by you may be used for the purpose of research, news reporting, commentary, or criticism. In other words, there are times when the use of copyrighted material is deemed appropriate without the consent of the one holding the copyright. To copyright music alone is not enough in many cases to protect your music, at least not without going through a lot of hoops in order to do so. One of the things you can do in order to protect your copyright is provide notice of copyright. This is a simple step that includes writing a simple statement to the effect of the word "copyright", the date, and your name at the bottom of your sheet music or on the case for the recording or the actual recording itself. CD's are the most common means for recording devices today and a notice of copyright can easily be added to the exterior of your CD or on your label if you have one printed. In case you are wondering: why copyright music? The answer is rather simple, so others cannot take credit for your creative genius. For an added layer of protection you may want to consider registering your copyright as well. Registering your copyright will provide you with formal legal documentation of your ownership of your music should anyone else attempt to lay claim to your music or any other dispute about true ownership/authorship come about. You must have your copyright registered if you wish to file a copyright infringement suit and it is, in my humble opinion, better to not only copyright music early on but also to register your copyright before it could possibly become an issue. Registering while not entirely painless is not as difficult a process as you might think. Basically it involves filling out an application, paying a filing fee (check with the U. S. Copyright Office for the current amount), and a copy of the work being protected (this will not be returned). It's also important to remember that your music doesn't have to be published in order for you to obtain a copyright. Music should be copyrighted and registered long before the publication process in order to protect your rights as the creator of the music. Whether you are dabbling with cute little limericks or writing masterpieces and concertos or are rock and rolls next super star you want to make sure to copyright music earlier rather than later for the best possible outcome should problems arise.
