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.

The Layperson's Copyright Primer Copyright laws are constantly changing, and knowing exactly what copyright infringement is, whether you?re creating an eBook, publishing articles, using music as a backtrack to your podcast - or what have you - is essential to selling your online media. Although the laws change from one jurisdiction to another, knowing the basic rules of copyright infringement will ensure you?re following the proper rules of engagement when it comes to creating your works. Before you make any final decisions regarding the use of a work that has been copyrighted, please contact a copyright attorney to ensure you?re following the law ? this will keep you from being sued or, even worse, punished in a court of law. What is Copyright Infringement? Copyright infringement, as defined by Wikipedia.org, states: ?Copyright infringement (or copyright violation) is the unauthorized use of material that is protected by intellectual property rights law particularly the copyright in a manner that violates one of the original copyright owner's exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative works that build upon it. The slang term bootleg (derived from the use of the shank of a boot for the purposes of smuggling) is often used to describe illicitly copied material.? So, what is copyright infringement in plain English? It means that if you?re not allowed to use something, then don?t use it ? plain and simple. It can be very simple to get permission to use a work ? many times you?ll be able to use a ?sample? of music or excerpt of written work for a nominal fee, or small attribution. However, if you do not have the permission of the copyright holder ? whether it?s an author or a publishing house ? you can be sued for copyright infringement or worse. What is Copyright Infringement in America? In many jurisdictions, such as the United States of America, this act is known as a strict liability crime or tort (a tort is a civil wrong ? not a criminal wrong). This means that the person who infringes the copyright - whether intentionally or not - will be responsible for the damage or loss. Also, the prosecutor (in criminal court) or plaintiff (in civil court) must only prove that the act of copying was committed by the defendant ? they do not need to prove guilty intent. This means, even if you had no intention of committing copyright fraud or infringement, you can (and in present times, in many cases, WILL) be prosecuted, even if you used the material in good faith. What is Copyright Infringement in action? Many cases of copyright infringement are difficult to see to the layperson, because the violation is not limited to exact copying. In many cases, when something is inspired by another thing ? such as in music, when the inspiration of one song is used to create an entirely different song ? it?s difficult to see where the new product or ?thing? has crossed the line to something illegal. Some works aren?t even protected by copyright, such as compilation of facts that lack the creativity necessary to be covered by copyright, or works that are in the public domain because the copyright has expired. Knowing the difference is often very difficult to see, and because of this we?ve seen a number of copyright infringement cases in recent years, especially in tandem with the music industry. As you can see, copyright infringement is a very difficult, albeit necessary, act to define. However, if you make sure that you?re using works that are in the public domain, or have long since been out of copyright (think Beethoven or Frankenstein) you?ll be safe. Do you fair research, and if you have any questions contact a copyright lawyer and ask ?what is copyright infringement? to learn the most up-to-date information for your jurisdiction. |
