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.

Copyright infringement case Learning Copyright Law through Copyright Infringement Cases Copyright infringement cases can be both costly and time consuming. Considering copyright infringement is something that isn’t as easily defined as theft or speeding, there are numerous copyright infringement cases that are changing the way copyright law is viewed in the United States of America. By reviewing a few of these copyright infringement cases, you’ll be able to get a better idea of what is, and is not, acceptable use of copyrighted works. As a forward, however, you’ll need to know a little bit about copyright law. Most copyright lawsuits are brought to the courts because a copyright owner has found their copyright is being used outside the copyright laws. This usually means that the copyright holder hadn’t been asked for permission to use the work, or if they had, that the work is not being used in an agreed-upon context or they have not been paid royalties. The copyright infringement cases, listed below, give a sampling of what goes to the Supreme Court in copyright infringement. Feist Publications v. Rural Telephone Service Co (6th Cir. 1996) This copyright infringement case was brought upon the Supreme Court in 1996 regarding the copyright of a database. The supreme court, in this instance, decided that compilations of data (such as in a database) are only protected by copyright when they are “arranged and selected in an original manner.” Although the level of originality needed to make the database copyright-able is not very high, the pages of a directory such as a phone book are not protect-able because the data contained therein is arranged geographically, then alphabetically. Because of this, the data was not original enough to warrant a copyright infringement charge, and the competing telephone company was allowed to tap into their competitors’ database and use that data in their own work without liability. Princeton University Press v. Michigan Document Services, Inc (6th Cir 1996) This case has to do with the ‘fair use’ law, which is defined in the Copyright Act of 1976, 17 U.S.C. § 107. In this case, a photocopying service was sued for copyright infringement for making ‘course packs’ for the University of Michigan. In this case, a course pack was a group of reading materials assigned by a professor – then the course pack was bound together by a professional copy shop. In the fair use system, there is a system available for payment of copyright fees to publishers whose works are used in course materials, the printing shop owner refused to pay the copyright cost. When it went to the Supreme Court, they analyzed the fair use code and found that it was NOT fair use, and the printing shop had to pay the copyright costs. As you can see, copyright infringement cases are cases in which someone violates the rights of a copyright owner, as provided by 17 USC §106, or of the author as provided in §106A. These copyright infringement cases can be taken to either criminal or civil court, and can carry with it a hefty fine. Copyright infringement cases are brought upon people who violate copyrights every day. In recent times, you’ll find many copyright cases in relation to electronic copyrights – such as those you’d find on a website or PDF file, as well as other digital media such as music and audio files. It’s probable that you’ve seen copyright cases brought against the common person – such as a child or family – for downloading digital music in the form of MP3s. In the current internet age we’re in, it’s not surprising to see so many music and video copyright cases brought to us because of peer to peer file sharing made possible by the internet. You can be certain that until people know the rules of copyright, and downloading copyrighted material from the internet that we’ll see many more copyright cases.

Five Positive Actions You Should Do After a Lay-off Lay-offs are hard for most people and are essentially difficult to cope with if you were and excellent worker and outstanding employee. Sometimes lay-offs are general cuts such as the closing of a whole department. It often times hits good employees that the company otherwise would have never gotten fired. So what do you need to do after you get laid off? Here are five positive steps you should take after you have been laid-off. The first and probably most important step is coping with the situation. Get your feelings straightened out. Of course you are upset and plain dumbstruck by what happened, but if you are not able to get this sorted out with yourself, the company is not going to take you back. Then you won’t even have a chance of finding another job. In some cases, if it was not very clear why you have been fired, it helps to talk to coworkers, and maybe the human resource person to just find out that it was not you or any of your doings that got you laid-off. Within this step falls also the realization that the job market currently is a tough one and that you might have to make some budget adjustments first off all. Do not be picky about what kind of jobs you want to choose. Sometimes, this means a new beginning, some job you might like much better than your old one, and you just do not know it yet. After you have been able to work through the situation and are ready for the job hunt, get your résumé out. If you have not been looking for a job in a while it might be dusty and not be up to date. Add your last job to the list; add your role and responsibilities to your list and maybe you even have to adapt your résumé to a more current style. Résumés and cover letters are your way into a job and the first impression that a new employer gets from you. When you are finished getting your résumé up to date, apply to as many jobs as there are. As a third step, make yourself clear that the job market is difficult and finding a new job might mean to apply for something that you might have not really wanted to do, maybe because you did study it, but you never really liked in the university classes? Well, it is worth applying for. The sooner you get another job, the better of you are. Face it, if you really do not like the work you can find another job after a year or two. After a lay-off it is very important to get back into the working world as fast as you can. To make your job search even more successful, as a fourth positive step after a lay-off, you also need to network. Talk to friends, other companies’ bosses you know, and anybody you have ever met that might have a job available for you. Besides networking, you can also always try to do some cold calling, writing letters to businesses that are not having a newspaper add out. There is always the possibility that they are looking for somebody. As a fifth positive action after you are laid-off there is always college. Taking classes that will refresh your topic and specialty you are working in can make a good bullet on your résumé. If the job market is quite tough, why not go back and finish that degree or add another maybe a graduate degree. This always is better on your résumé than plain being out of work.
