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: 209.131.36.158
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 Infringement Lawsuit Who are in Copyright Infringement Lawsuits? A copyright infringement lawsuit can be brought down for any number of reasons: someone using a song in a podcast or radio program, a writer ‘borrowing’ information from another work, the copying of video or mp3 off the internet without permission (or sometimes, even to another CD or DVD). Copyright infringement lawsuits are not generally brought to the average person, unless they’re downloading a LOT of music or movies, but usually for large operations: software pirates reselling goods on eBay or to some other unsuspecting victim, someone ‘sampling’ a song to make another, or maybe a person reselling mp3s online. When you understand the implications of it, copyright infringement lawsuits aren’t frivolous as some people may make it seem. For the most part, the average person’s familiarity with a copyright infringement lawsuit is taking down copyrighted material after receiving a nasty email. The use of works that are used in major record albums my major recording stars like Britney Spears or 50 Cent, people will begin copyright infringement lawsuits for songs that bear resemblance to another song. Usually these suits will be lost because it’s rather hard to prove inspiration, but they are rather costly and draining, especially if there isn’t a large backing legal team. Copyright infringement lawsuits for large enterprises can be rather costly and time consuming as well. If you work for someone, and you plagiarize someone on the company blog, the whole company can be sued, and you fired, for that infraction. Another large copyright infringement lawsuit is the eminent MySpace v. Universal Music Group, who is claiming that MySpace is knowingly committing copyright infringement by allowing it’s users to upload copyrighted material. Even then, Universal Music Group has been negotiating with MySpace and couldn’t come to an agreement – then they filed suit. Universal Music Group has an agreement in place with YouTube, where YouTube agrees to follow Universal’s rules. It’s worked out well thus far, and I think with an agreement in place ‘user created content’ will retain a destination on the internet. This is a testament we all need to be with social networking sites and ‘user created content.’ We need to watch ourselves, because many times we may not realize the veracity of our actions. Sometimes, people break copyright laws on purpose. There is a huge market in the dealings of pirated software – from Windows to Photoshop to The Sims. It’s very easy to share peer-to-peer, and because of that, people can resell ‘pirated’ for a high price – all profit. Or they’ll download MP3 and resell them; or eBooks. These people who resell these items get nasty penalties – with both copyright infringement lawsuits and criminal cases. They’ll pay a hefty fine and go to jail. As you can see, copyright infringement lawsuits can affect any one of us – from our friends on MySpace to our employer, to the computer geek down the street. It’s very easy to violate copy rights, and you have to watch yourself. The chances are good that you won’t be involved in a major copyright infringement lawsuit, but you still need to ensure you’re following the copyright rules of engagement. Copyright infringement lawsuits are important in determining what is, and isn’t, applicable to copyright laws. Because of these lawsuits, our laws have changed regarding fair use, internet use, and the Electronic Frontier Foundation and CreativeCommons.com has been formed. The lawsuits help us to understand what is, and what isn’t fair – and these organizations have helped the masses to understand what’s so important about copyright, and why we need to defend our freedom of speech. Short Trips: Articles are Great Ways to Enter the Writing Market (writing articles) Not everyone who loves to write is destined to become a writer. Most people define a writer as a person who makes a living from their writing. Writers are committed to a career of difficulty and very hard work. Not that every other job doesn’t include work, but writers make up a group of individuals who are less recognized for their contributions. Certainly there are famous writers who are appreciated for their efforts, but they do not represent the majority of those who take up a pen for their livelihood. If you love to write, but you’re not sure about taking the leap into becoming a writer, there may be a perfect option for you to use your skills. Writing articles is a writing job that can be taken up to whatever degree you would like to do so. Types of Articles to Write Because articles are such short pieces, each one can only cover the smallest piece of information that the world contains. Depth and length are limited by each other and so writing articles allows you to focus on just about anything you’d like. If the articles cannot cover the scope of material that you’d like to cover, you can write more. Articles come in all kinds of packages. They are written for magazines. A magazine will always have a general topic that it strives to cover. Within the broad topic though, there are thousands of possibilities for the creation of articles. Newspapers are more directed towards current events rather than interesting tidbits or random information, but they also must buy articles in order to be printed each and every day. There is also the possibility of writing articles for the internet. In that genre, the topics expand exponentially as time goes on. The opportunities are out there, so how do you start writing articles? Getting Hired for the Work To get hired to write articles you mostly need the ability to market your writing skills. There are many, many good writers in the world. To get hired to write, you must be better than good. You must be able to use your words to describe, explain and convince. You must let an editor know why you are the right writer for a particular job. If you can write effectively enough in your resume and cover letter, an editor will know immediately that you have the skills and abilities to write equally convincing and interesting articles. If you are interested in continuing in the process of writing articles, you must know how to construct great content into a great finished product. Writing Great Articles If you can allow your curiosity to drive you, you will never run out of the ability to create great articles. The first rule in writing articles is to be ever ready to learn something new. You never know when you’ll need that piece of information to back up your writing. The idea for writing articles is only half of the battle though. You also have to actually do the engaging writing. This is where you pull out all of your literary tools. Write with enthusiasm so that your reader will be enthusiastic. Write with variety and slight complexity so that your reader will not be bored. Add a little bit of suspense as you are writing articles so that every reader will keep going until the end. Writing articles can be a career, but it doesn’t have to be. The beautiful thing about article writing is the short term nature of each project. You will move from one topic to the next as you continue to learn and expand your writing abilities. Writing articles can take you from your front yard to across the world in as short of trip as you need it to be. If you are considering the possibilities available to you in a writing job, investigate the possibilities of article writing. If you are a writer, you’ll love the work. |
