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.
Get Noticed at your Job by Doing it with Flair Doing your job with “37 pieces of flair” may have entered the pop culture vernacular through the famous movie about life working an office, Office Space, but there may just be something to it. You might not need 37 pieces of flair, but doing your job with a little bit of flair and a lot of hard work is a great way to get noticed in the office and to move on to bigger and better things. How do you go about doing your job with flair? The first way to make sure you are doing your job with distinction doesn’t involve much flair at all – it simply involves doing your job and doing it well. Know exactly what your responsibilities are and attend to them every day. Don’t let any of the things that come under your job description fall by the wayside because you think they are unimportant. If you are unsure exactly what all of your responsibilities are, ask your boss for a meeting and discuss your job description with them. You will get noticed simply for your desire to make sure you are covering all of your bases and not letting any of your responsibilities fall by the wayside. Another way to do your job with flair is to add to the good morale in the office. Everyone has at least one person in the office that is like a black cloud hanging in the air. Gloom, doom and pessimism don’t really have a place in the office. Even if you feel like you are heading for a fall with the way a certain project is coming together or because someone on the team is not pulling their weight, look for solutions instead of standing around and complaining about it. When your attitude can help people stay on track with their work and not dread coming into the office every day, you are bound to get noticed. If you really want to add some flair to your work performance, learn how to manage your time and avoid procrastination. Time management is one of the biggest problems all employees face, and when you don’t manage your time efficiently, you are not being as productive as possible for your boss, which never wins you any fans among the management team. If you find yourself always rushing through your work at the last minute trying to meet your deadline, try keeping a journal of all of your activities at work for a few days. When you see how much time you spending doing things like talking with co-workers by the water cooler and surfing the net, you might see ways you can improve your work habits, so you can get things done well before the deadline is pressing down on you. Increasing your productivity by managing your time is a surefire way to earn some praise from the people over your head. Another way to add flair to your work performance is by being a team player. It can be tempting to thing that to have flair you have to go out on a limb and try to do everything yourself, but that is not the case. Employers don’t like to see an employee trying to hog credit for things that everyone has worked on together or trying to one up everyone else on the staff. When you work together with the team, you show your employer that your interests are with making the company a success and not trying to advance you own personal agenda. If your employer understands that you see the bigger picture of making the company succeed, you are sure to get noticed and rewarded. The Road to Riches – Or at Least Success - In writing (how to become a published author) Getting published is the first step on the road to becoming a writer. It’s an exciting day when you receive your first paycheck for something you wrote. It’s a stamp of approval on your ability to write the meaning of the everyday for the general public. If you want to know how to become a published author, read on. It can be a difficult and frustrating road, but the destination is well worth the journey. Starting Small The first thing to remember when wondering how to become a published author is that beginning should look like a beginning. Don’t expect instant recognition or huge payment for your first efforts in the writing world. You will learn as you continue to write and get feedback. Don’t always expect feedback either. You will have to become your own critic to some extent. The following list includes great opportunities for publication as you improve your writing skills. Newsletters As you learn how to become a published author, your first lesson may be that you won’t always get paid. When you are first starting out, your best opportunities may be with free publications that only accept donated work. Many newsletters are created by non-profit organizations. They need donated time from several sources in order to keep the public informed about their work. You could start your practice there. You can also start the process towards name recognition. Newspapers Newspapers are also a good place to begin your publications. Reporting jobs are difficult to land and may not be worth the time and effort that they require, but you can start with letters to the editor for great practice. You’ll see your name in print if you can write a clear letter addressing relevant topics. That could lead you to a relationship with the editor so that you can move into a few freelance jobs. Magazines As you query magazines for possible publication opportunities, you will do well to include some of your already published work. Whether you’ve been compensated or not, your name in print along with some representative writing will help you get an interview with a magazine editor. Now we can talk about how to become a published author for money. Magazines start writers at low wages with the opportunity to increase. Online Publications Online publications work in much the same way. You will probably find job postings on job boards. If you can demonstrate that you have been published somewhere before your chances of landing a paid job will increase. Anthologies As your skills improve, you will be able to step into jobs with books. Anthologies are filled with skillfully written pieces along some subject line. You will need to use all of your capabilities you have learned so far as in writing for an audience and creating a tone acceptable to the publication. If you can do that, you will start to enter into the world of books. You may want to stop there, or you may want to take your work further. Books Writing your own book will take time and work. As you think about how to become a published author, remember that you do not necessarily have to become a book author. Writers work in all fields, and some are limited to one or two. If you have enough motivation and capability, book writing can be a lucrative field to enter into. If you’d rather stick to short term projects though, stick with the magazines and other similar publications. If you need more information about how to become a published author, check out specific information about any of the above genres. The internet is a great source, but you can also support other writers monetarily by visiting your local book store. |
