Web Hosting - DNS, How The Internet Keeps Track of Names
The way computers communicate is, in a way, very similar to something very familiar: the postal system that delivers letters and packages. Here's how...
The Internet is just what the name suggests, a large inter-connected set of networks. But those networks are pointless without the one part that forms what is called their 'end-nodes', otherwise known as computers. Those computers often need to share information because the people who use them want to share information.
But, in a system where there are millions of separate computers, how can you enable them all to communicate? One very important feature of that solution is performed by something called DNS, the Domain Name System.
Every part of a network that is going to send or receive information is assigned an IP address. That's a numeric identifier that uniquely specifies a particular 'node', such as a computer, a router that directs traffic or other component. They look like this: 184.108.40.206
But those numbers are more difficult for people to remember and work with. They also aren't very attractive from a marketing perspective. So, a naming system was layered on top of some of them, mostly the computers involved, though routers have names, too.
But once you have a system that associates a unique IP address to a given name, you need some way of keeping track of all of them. That's carried out by several different pieces of the system: Name Registrars, DNS Servers and other components.
The Name Registrars, overseen by IANA (Internet Assigned Numbers Authority) and other international bodies, provide and keep track of domain names. When you register with GoDaddy or any of a hundred other intermediate companies, ultimately that information makes its way into a number of specialized databases stored inside DNS Servers.
A DNS Server is the hardware and/or software that tracks and forwards the IP Address/Domain Name pair from one place to the next. In many cases, there are a number of them between your browser and the remote computer you want to share information with.
Suppose you request information from, say, Yahoo's site by clicking on a link on their site. DNS resolves (translates) the name of WHO IS making the request and OF WHOM, to addresses, then passes the request through the network to the requested IP address. The requested data is then passed back through the mesh of network components to your computer and displayed in your browser.
Whether the communication is between a desktop computer and a server somewhere, or between one server and another, the process is essentially the same. DNS servers translate names into IP addresses and the requests for data are forwarded on.
In some cases those DNS servers are part of a specialized network computer whose sole job is to do the translation and forwarding. In other cases the DNS software may reside on a server that also houses a database of general data, or stores email, or performs other functions.
But however complicated the chain or the parts, the basic process is simple. Translate the name to an address, just as the postal system does. Whether international or local, your name is associated with an address, and the deliveries are made to the address, then forwarded to a particular name.
Copyright music expiration For Many Copyright Music Expiration is a Luxury for Worry If you copyright music, expiration isn't something you have to worry about, at least not in your lifetime. The music that you've written is copyrighted the moment you've put it onto paper or recorded it being played. The reason you don't have to worry about expiration is because the music is protected until 70 years after the death of the author. In the case of your music, that author would be you. This rule about copyright music expiration was first put into place so that the families and heirs of an author could still earn royalties even after his or her death. Ultimately this means that if you've taken the steps to copyright your music and have registered the copyright then your music will be protected throughout your lifetime until 70 years after you or the last surviving author (assuming a collaboration) are no longer living. Copyright music expiration is not something you should make a primary concern unless you are having issues of someone respecting and/or honoring your copyright at the moment. You should take comfort in the fact that as long as you are alive you are the only one who can assign your copyright to another person and as long as you haven't given up your ownership of the music it still belongs to you. This is different however if your copyrighted music was work made for hire. If that is the case then you cannot have ownership of the music, as it never legally belonged to you no matter what form it was in when it changed hands. Works made for hire have different copyright music expiration than those that were owned by the creator. With works made for hire, the copyrights are in effect for 95 years from the original publication date or for 120 years from the creation of the work whichever of the two is shorter. For most beginning musician?s copyright music expiration date isn't as important as getting that first gig or earning that first dollar as a result of the music he or she writes and/or plays. It's about art for many and about survival for others. The latter are quite often the ones that are taken advantage of. These are the authors who don't protect themselves as they should and end up failing to register their music because the idea of buying food seemed more pertinent to survival at the moment. This is often the case, particularly among street musicians and it's something that was becoming a growing problem immediately after hurricane Katrina devastated New Orleans taking with it many of the homes of starving musicians along with many pieces of music that will never become copyright music, expiration or not, those works are gone forever except in the mind of their creators. who could barely scrape together the money to pay $100 a month for a hovel they shared with 6 or 7 other people in order to keep expenses down and avoid living on the streets. The building not only of homes for those musicians displaced as a result of Katrina's devastation is wonderful but even more than that is the fact that there are organizations that are dedicated to creating a community for these musicians so that maybe many of the struggling artists won't be taken advantage of or have to face the decision to register their music in order to protect and copyright music expiration for their future heirs or to risk loosing their claim over the music they wrote in order to eat or pay the rent or buy groceries.
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.
