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.
Learning How to Become a Writer in Three Steps (how to become a writer) Becoming a writer is hardly a simple feat. To become a writer a person must practice and work hard to become a writer. It can be said that many writers are writers, but few of them know how to become a writer. The label “writer” is just simply a label, it is all the hard work and determination of reaching that status that truly gives the writer that name, and makes them worthy of the title. There are three simple steps that any writing can take that will give the title of “writer,” while making them worthy of it. The first step to becoming a writer is to claim yourself as a writer. Many writers believe that they cannot be known as writers until they are published, but this is not true. Anyone who thinks of themselves as a writer, and writes on regular basis should title themselves as a writer. Many unpublished writers have the habit of saying they want to write, or saying that they write, instead of saying “I’m a writer. When learning how to become a writer, it is necessary for writers to realize that you don’t have to be published to be known as a writer. Although, it may seem ideal for introductions and make it easier for other to see you as a writer, being published does not make one a writer. Writers should see themselves as people who write, and not as people who write for a living. For most writers, being published is validation of their status as a writer and even a path to success, but there are many published writers who are not very successful, famous, or rich. However, being published is a great way to show your work to an audience, and gain recognition, no matter how big or small. On the path to becoming writing there are many who lose sight of the fact that they don’t stop writing once they are published, so it is not wise to only write to be published. There are many ways to claim yourself as a writer, and in this step to learning how to become a writer there are smaller steps that help you proclaim yourself as a writer. First, say the words aloud to yourself, and repeat them as many times as possible until they are believable to you and others around you. Next, find a specific place for your writing, which can be a room, section of a room, or a studio. It is also important to make the “writing space” as comfortable as possible, and to make it viable to your writing needs. Then, it is important to get the proper writing tools, such as pens, pencils, notebooks, and a computer that is used specifically for your writing. Aspiring writers can also find lessons on how to become a writer in style books, which should be kept as a writing tool also. It is also helpful to befriend other writers, and read their work and others as a writer and discuss passages of books or chapters with other writers. The second step to becoming a writer is to make time to write. When learning how to become a writer, novices will always be advised to make time for their writing. Many aspiring writers usually mess up on this step, and although they want to be writers they slack on how much they write, so many writers are left with unfinished works. It is important to set aside a particular time or day for writing and to stick to that schedule, because deviance from a writing schedule usually means unfinished work. The final step to becoming a writer is by far the simplest. To become a writer it is imperative that you write. Writing is the simplest step to becoming a writer and the most important step. When learning how to become a writer, you must take some time out and write. Copyright Law Plagiarism Plagiarism Is Simply Unethical Anyone who is a writer is concerned with plagiarism. Copyright Plagiarism Laws protects copyright holders from having their works plagiarized. Many people think it is ironic that the word plagiarism derives from “kidnapper” in Latin. However, it is true. If a person uses another person’s words without permission, they have indeed stolen or kidnapped something that was owned by another and is in violation of copyright law. Plagiarism is a very bad word in the writing world. Crediting the author of the work will not keep someone immune from being in violation of copyright law. Plagiarism is plagiarism, even if the author is cited if the author did not give permission for the work to be used. One of the most common areas that copyright law plagiarism is violated is in the academic world. Many students will copy and paste the information they need for their research papers and essays straight off the Internet and turn it in to their professors. However, this type of cheating is easily detected now with special programs that professors can use. Plagiarism is unethical, not only in the writing world, but in the academic world, as well. Did you know that you could plagiarism a work but not be in violation of the copyright? Likewise, you can be in violation of a copyright and not have been plagiarizing. It is really not that hard to understand. Let’s say you are using Abraham Lincoln’s exact words in a paper and you did not cite him as the source or give him credit. Well, Lincoln’s words aren’t copyrighted because they are in the public domain. But, you did plagiarize because you tried to pass off his words as your own. Alternatively, if you use a picture in a book and you did not gain permission to use the book, you have violated copyright law because you did not source the artist and you did not get permission from the artist to use the picture. If you are in school, the best way you can get around committing plagiarism is to simply list your sources. If you use someone’s word, list it in an endnote or in a footnote. List the resource you found it in the bibliography. Another way around copyright law plagiarism violations is to take notes when you are reading. Take notes in your own words and put the resource away. Write your paper from your own words. No one wants to be singled out for plagiarism, especially a student who is concerned about their reputation at school and writers who need to keep their credibility in good standing. With today’s technological advances, it is not too hard to pinpoint plagiarized work. Even webmasters who run websites are on to the plagiarism crowd. They can run their entire sites through a special program to see if their content has been stolen and duplicated elsewhere on the Internet. If you are dealing in the written word, either academically or as a profession, it is a good idea that you only use your own words. It was probably easier to get away with plagiarism 100 years ago, but it is not that easy today. The changes are very high that if you are caught violating copyright law plagiarism laws you will be caught. Not only is it embarrassing, but it can cost you a bundle in a lawsuit. |
