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.
Ghost Writer: Who Uses Them and Why (ghost writer) A ghost writer is someone who is hired to write for another person under their name. In most cases ghostwriters do the work while the hiring person gets the credit. The use of a ghost writer is huge business. People in virtually every aspect of life could use a ghost writer. A ghost writer will need the ability to become the person they are writing for. The writer has to be able to use their mannerisms, their words, and their way of speaking. The writing must read like they are coming from the person themselves. Being a ghost writer means that you give absolutely all rights to the credited author. You will need to decide if it is worth it for someone else to take credit for your work. There will be confidentiality clauses in your ghost writing contracts. They will state something to the effect of legal action will be against you if the writing is reproduced by you in any way shape or form. There are many reasons why a person would use a ghost writer. Celebrities and public figures use ghost writers to write their biographies and memoirs. Ghost writers are hired to make celebrities sound as interesting and compelling as possible. Their purpose is to pen the stories into best selling books. Motivational speakers may use ghost writers to write self help books. Just because they are great speakers does not mean they can pen the words on paper. Or they just may simply not have the time. There are many types of ghost writing opportunities available. Non fiction writing would be your biographies, autobiographies, how to books, and memoirs. A ghost writer’s role in non fiction could range from the very minimal to the most complex. They may be given an almost complete manuscript and asked to add some finishing touches. Or they may have to start at the bottom collecting research and following the project through until publication. Accomplished fiction writers may use ghost writers to carry on a series of books after the author has passed or to carry out the series while they work on new ventures. The Author may have an established pen name that they use a ghost writer for while they write under the real name. Ghost writers are often used for scripts and screen plays. They are hired to finish and polish the writings of the authors. High school and college students will hire ghost writers to write their entrance essays, thesis, and term papers. Although this may seem unethical, it is legal. The writing and selling of the paper is perfectly legal. It is when the student turns the paper in as his or her own writing that it turns into an illegal action. The political venue for ghost writers is to correspond to the letters that they receive. Official will review the letters before being sent. A political speech writer is often considered a ghost writer. But others will argue this since it is public knowledge that political officials do not write their own speeches. In order to succeed as a ghost writer you must have excellent writing skills and often be able to take on the personality of the credited author. You must also be a great sales person in order to sell your service and be able to prove that you are the best possible choice for them to use you in their endeavors. Making the decision if ghost writing is right for you may be a difficult one. It is often hard for writers to give up all rights to their work. Explaining How Credit Scores are Used in the Hiring Process You might be wondering why credit scores are used in hiring processes. While you may have never heard about it, it is actually a more common practice than you might think. Companies and institutions such as banks, universities, retail stores, financial institutions across the United States use credit scores to determine whether an applicant is good for the open position or not. Even though you might think that this is illegal, it is not. In general, it is a legal undertaking for companies to look at your credit score. This is yet another reason why you should make sure that your credit scores are good and up to date. So why would they be using your credit information in a hiring process? For some of these companies, employees will be exposed to a lot of money and have a financially responsible position. Your credit information can actually help them determine whether you are a financially responsible person or not. Companies think that if you cannot handle your own money, why you would be qualified to handle their money? On the one side, if you think about it, it is a very valid thought. On the other side, the credit history will not tell the company how you might have gotten all the debt. What if one of your family members is really badly sick or a similar situation? In this case, you have not been irresponsible with your money, but you saved a family members life. You might have been willing to take on all this debt and then work from there. Sometimes numbers are just not an accurate representation of your life. Companies that do use your credit are not only determining whether you can handle money, in some instances they use it as an indicator for your character. It will tell them if you are responsible with your money and finances you are a responsible person. A person that will not be tempted by money or certain situations in a workplace is a person they can securely trust with their funds, their tasks or their great projects. One thing is for sure, the company needs to let you know that they are going to check your credit history in their hiring process and they also need to let you know what they are checking for. The criteria they are looking is the criteria they have to tell you about before you give them the permission. Unless they tell you and have a signature of permission from you, they are not allowed to check and use your credit history. If they miss these above mentioned steps, you do have a case in you hands that you can bring to the court. In some instances, some of the people that were not told about the credit check and have been denied have had a good case in their hands. But as with so many things in life in the United States it pays off to have a good credit history and such a check will not ruin your career moves. Check your credit history every year since once a year the big credit companies do have to give you a free credit report. In the case that you find any wrong or dubious items on your account go ahead and dispute them. Oftentimes companies might just have put a claim against your account that is not really caused by you. Why do companies do that? Money has caused many bad things in the world and a company that wants their money back is going to run after any lead they have. Therefore disputing your case and putting your credit score back to normal can be an essential part in your application and hiring process with some companies. |
