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.
How to Be a Better Employee when You Work for Yourself Whether you are just starting or you have had your own business for many years, there are many reasons why you would be a better employee when you work for yourself. The biggest reason of all is probably that you work to make your own living. You do not just get a salary. If you as the boss and owner of the business do not produce the work and effort needed, you most likely will not make any money. If your business is not only providing for you, but also for you family, it is even more important that you make profit of your company. No profit and income from your joint venture means no food on your family’s table and that is a serious problem. For this monetary reason, many self-employed workers work harder, longer and put more effort in than other employees. Another reason lies within proving that your business can be successful. You want to be top-notch in what you are doing. Whether it is manufacturing products or offering services, if it is your own business, you are taking pride in what you do and you want to prove to customers and others that you are their first choice. Then you need to deliver quality. Often times as an owner of a business, you make sure that everything is one hundred percent and that is more than you would most likely give for somebody else’s business. If you work for a company as one of their employees, you might wonder why you should work long hours each and everyday, without the benefits. However, when it is your own business, money flows right into your pockets and every profit you gain from working harder can be yours immediately. Also, if you belong to the group of people that like to decide when they start work, when they finish and what they do, then being your own boss is probably one of the best choices for you. It is easier to work better and give more energy in what you do when you can decide what exactly you want to work on. Of course, some things always have to be done, but you can more or less decide whether you want to do it now or at ten o’clock at night. Did you also know that most of people would work better when they are having people that are under them? You are trying to set an example in work ethics, hours worked and projects completed and therefore, you will put extra effort in what you do when you are working for yourself. Your employees take you as an example for how they should do their work and if you just hang around and do nothing, why would your employees be motivated to do something? But if they get feedback and motivation from you and can see that you put just as much effort or even more into the company, they are more likely willing to follow in the footprints that you have left for them. Keep in mind, that when working for yourself, you are your own resource and motivator. Therefore it is important that you keep better work ethics than when you work for somebody else to not risk what you started. A hard working company owner most often gets rewarded with a growing business and happy customers that will come back year after year. Customers do like to be appreciated and a hard working business owner that will get on their case immediately is one way of appreciation to them. How to Succeed as a Writer in the World of Freelancing (freelancing) Many may view freelancing as a writer as an acquired taste. There are many things about freelance writing that may be deemed as undesirable for many writers, including the common low pay and high demands. However, most writers would consider the freelance writing field, and many enjoy the freedom of freelancing. Being a freelance writer involves writing as well as the marketing of oneself and one’s work. For freelancers, it is important to give careful attention to the business details of the writing world, such as quarterly taxes, and staying ahead of the changing trends of publishing. Freelance writers also have the job of writing according to the editor or publisher’s rules while staying true to their own style. Being a freelance writer may seem ideal to some writers, but in the world of freelance there is stiff competition and most writers receive a hundred rejections before receiving one letter accepting their work. Many freelancers don’t consider being a freelance writer as an easy job, but there are some steps that can help turn any person succeed as a freelance writer. First, it is important that the freelance writer is honest about the quality of their writing and the depth of their writing skills, as well as their knowledge of freelancing. Editors will not spend time with submissions that have many grammatical or spelling mistakes, so it is important to know your own limits, learn your weakness, and use your strengths when writing on a freelance basis. There are many freelance writers who consider themselves professionals, but who don’t have the proper training or degree in any field of writing. So, the next step to being a successful freelance writer is to take a writing course or attend a workshop. Learning techniques from an instructor can be very helpful to a freelance career, and may inspire some writers to move higher on the career ladder. Writers may benefit from receiving comments on the quality of their work from instructors and peers, and may benefit from the pressure of writing well on deadlines. Freelancing requires a certain amount of promotion of oneself, and writers must learn how to write query letters to editors well. For freelance writers, a query letter briefly proposes their idea for an article, gives their qualifications as a writer, and makes the editor believe that the idea is better than every other idea out there. Next, the freelance writer should use web sites for writers to improve their writing skills and to find freelance job opportunities. Many writing web sites have features that are very helpful to writers, and some even offer advice and lessons on how to become a freelance writer and how to maintain a freelancing career. Freelance writers may find it difficult to begin their career, but a simple starting point is the local newspaper or local magazines. It is usually best for a writer to contact the local paper or magazine and ask to submit an article “on spec,” which means the editor may choose not to pay for the article but will be willing to read it. Typically this method works as a good introduction into the freelance process and world, and helps the writer learn the proper techniques for presenting work. Freelance writers should also work on many small points to improve their career, such as professional presentation. It is advisable for a writer to create a portfolio of clips that prove that they have experience as a writer. This may be difficult for inexperienced writers, but they can begin to build their portfolio by volunteering to write for community publications. Online communities also offer writers the opportunity to write and create material for their portfolio. Freelancing may not be desirable for all writers, but for many it is passion, and some believe the writing world cannot survive without freelancers. |
