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.
Software Copyright Laws Software Copyright Laws Fail to Provide Adequate Protection Software copyright laws are among the most difficult to enforce among the masses. Many companies and corporations are also well known for overlooking these laws, which were designed to protect the makes of software from not earning their worth. Perhaps one of the biggest hitches leading so many software businesses to go out of business is the fact that they have a great deal of difficulty actually enforcing the software copyright laws that are in place and getting the money that is owed them according to the agreements that have been made with those on the using end of the software. Software developers, particularly in the corporate world design software that makes other companies run more efficiently. The software allows these companies to save millions of dollars each year. Software copyright laws protect the interests of the software developers that create these massive programs. These programs are often designed specifically for that one company and are very expensive. The agreement often consists of a certain number of users with the company purchasing more licenses or copies of the software during expansions or paying some sort of royalties for the use of the software. The purchasing companies agree to this and then more often than not fail to honor that agreement. The agreement is what allows this company to use that software, this agreement is what allows that permission. When companies aren't living up to their end of this agreement they are not only guilty of breaching that agreement but also of breaking software copyright laws. The trouble always lies in proving that they are not honoring the contract and the extent and duration of the breach. Some of the ways that companies will argue in defense of them not paying the royalties, additional fees, purchasing additional software, etc. is that they upgraded computers and reused the old software (they did actually purchase the rights to use the original software and by doing so feel that they have broken no software copyright laws) the problem lies in the fact that adding ten new computers and placing the software on those should mean that you remove it from or get rid of 10 old computers. This is rarely how it works. So now they've basically stolen ten copies of software that can be well worth hundreds of thousands of dollars. Multiply this by 10, 20, or 100 companies trying this or worse each year and the offending companies are costing software developers millions of dollars in profits. This is when software copyright laws are not as far reaching in their scope as they really need to be. Software copyright laws exist to protect the software companies from this type of abuse and misuse, however, the hands of the companies are almost unilaterally tied when it comes to proving that software copyright laws have been broken in court. There are always exceptions to every rule. In this case big business software developers that abuse the software copyright laws to the point of breaking make the exceptions rather than miserly consumers that do not wish to pay for the products they are consuming. The big boys are able to do this by offering licenses for their software and claiming that these laws do not apply to their situation because they are not actually selling the software only 'renting' out permission for people or companies to 'use' that software. The true irony is that these practices began as a response to the corporate irresponsibility mentioned above. It's amazing that the very software copyright laws that were created to protect these companies can't protect their consumers from the greed of the developing companies.
