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.
Continuing Education Key to Being a Better Employee Employers now recognize the importance of continuing education for employees. Over the past few years, more and more employers have begun to offer tuition reimbursement and continuing education classes to their employees. While this was once thought of as an excessive expensive, it is now understood that continuing education benefits the company as much or more as it does the employee. The job market is becoming more and more competitive everyday. Only the best employees are getting jobs in certain sectors. That means that your skills need to be sharp in order for you to remain valuable to your company. This is where continuing education comes into play. No matter what type of job you have, just about all companies are investing in continuing education. The reasons why are simple. Even though the company may spend a good deal of money on continuing education for their employees, they see an even larger return. By having employees that are on the top of their game, the company will be more productive as a whole. Thus the company will make more money. With that in mind, it is very important that employees always take advantage of continuing education classes when they can. You will be able to stay on top of whatever new trends are coming up and possibly acquire skills that will allow you to move up in the company. By taking continuing education classes, you will become more productive. Studies have found that employees that continue to have their skills refreshed and renewed are more productive on the job. This is a perk for both employees and their employers. You will be able to finish more work in less time and with more understanding. Thus making your time at work easier. If you are not sold on the idea of continuing education, think of it this way. Your employer is paying for it. It is a perk of your job that you should take full advantage of. If you are working towards acquiring skills that will lead you to a promotion or an entirely new job, you are doing something to better yourself. And, it is costing you less, or nothing at all. The best companies to work for in the country have great training programs. This is no coincidence. These companies, which also make a ton of money spend thousands of dollars training their employees so that they can go out and make the company the most money possible. Less successful companies have begun to follow suit. No matter what type of job you have, there are continuing education programs that can help enhance your job experience. Continuing education is a great way to break out of a rut. If you are eager to change jobs or get a promotion, you will fair much better in the job market if you do some continuing education. Use whatever means your company offers to better yourself and become more marketable. The type of continuing education you choose depends on your career goals. It is always helpful to have an advanced degree in a certain field. If tuition reimbursement for graduate school is an option, take it. Having a Master’s or PHD will help you become an expert in your field of study. If your job has company continuing education, take them up on it., Even if a promotion is not exactly what you are looking for, being cross trained is always a good idea. Gain as much in the way of knowledge and skills as you can. When you move on to your next job those skills will look great on your resume. Copyright music lyrics To Copyright Music Lyrics is to Protect the Wealth of your Future Whether you copyright music lyrics or the notes to a song you have a certain amount of ownership in the song. This is one of the many instances where the copyright affects more than one person and results in being valid until the last remaining person on the project (of course you must be identified in the copyright in order for this to affect you) have been deceased for at least 70 years. The easiest route for musicians is not just to write the notes but also to copyright music lyrics at the same time. This is much better for everyone involved and there is only one registration fee rather than creating a need to register the music and the lyrics as separate entities. For those who are new to the entire process of registering copyrights, owning copyrights and wondering exactly what happens now that you've registered it can seem like either an extremely complicated or confusing process. Many new artists fail to properly protect themselves and their non copyright music lyrics from those who would take advantage of them. If you are hoping to copyright lyrics that you've written for a song, I strongly recommend copyrighting music lyrics and registering them before introducing the lyrics to the music of the song unless you wrote both the lyrics and the music. Doing all of it together is often more difficult, particularly for those who feel more talented or gifted in one area than another but it really does help keep everything together and straight over the long haul. It's also great practice to write your own music rather than focusing only on the righting of words. After all, you had something in mind when you wrote the lyrics (a tune, a melody, something) and only you can truly give the unfinished artwork the justice it deserves. So many people forget how similar creating music is to creating visual art. Both require dedication, visions, purpose, and passion. They require different skills but very similar emotions and qualities in order to do well. Once you've begun to copyright music lyrics there really is no major difference between moving on to the next task, which is actually writing and copyrighting the music to go with those wonderful lyrics. If you're not a great music writer, then it is probably preferable that you find someone who is to work on this project with you. Perhaps your next copyright music lyrics session will lead to some wonderful collaborations and joint ventures. Many times in music the hardest part of any big break is in finding the right partner with whom to work towards your common goals. Most bans fail because they either never shared a common goal or someone in the band changed the goal without consulting anyone else. The vast majority of marriages break up over very similar claims. Perhaps the cruelest point of all to make is that not everyone who can copyright music lyrics will be completely honest about the source of the lyrics or the period of their lives while leading up to that point. The sad news is that we live in a world that isn't going to easily take someone's word that they created those lyrics, particularly if someone else already has a copyright on those very same lyrics. If you aren't the ones writing the lyrics, or the music for that matter be careful that you don't end up trying to pass of copyright music lyrics or notes that aren't your own creation, this could definitely lead to more harm than good in time. More than anything else is extremely dishonest and unbecoming of a musician. |
