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.

International Copyright Law Surprise! There Is No International Copyright Law Many people are surprised to learn that there is no international copyright law. Yes, that is right. There is not an international copyright law that will protect your work on the other side of the world. However, it is important to note that most countries do offer some form of protection to what is deemed as “foreign” works. International conventions and treaties have done much to protect owners of copyrights around the world. With the world seemingly becoming smaller every day the United States took a look at its stance on the European copyright treaty known as the Berne Convention. Basically, the Berne Convention of 1886 involved European nations coming together to seek a uniform copyright law to keep their copyright owners from having to register for copyrights in individuals European countries. The United States signed on to the Berne Convention introduced made it into a U.S. law known as the Berne Implementation Act of 1988. If you are seeking to have your work protected in a particular country you need to find out what kind of protection foreign authors have in that country. Some countries offer little or not protection to foreign authors. It should be noted that the U.S. Copyright Office is not allowed to give authors recommendations or the names of attorneys or agents that could help them understand foreign copyright laws. However, with a little investigation it is not hard to find someone who is an expert on foreign copyright law. These individuals can help you learn more about copyright protection and how your work is deemed in a foreign country. Someone who works in international copyright law will tell you that it is different than most other sectors of law. It involves knowing the copyright law of two or more countries. Every country has their own way of granting and protecting someone’s copyright. The individual criteria of each country must be taken into consideration when you are dealing with international copyright law. It is important to note that some countries do not have any intellectual property rights and some countries even grant more copyright protections than even the United States. International copyright laws involve understanding international treaties and conventions, like the Berne Treaty and WIPO Copyright Treaty listed above. If you are interested in pursuing a degree in law, you may want to explore the international copyright law sector. With the world becoming one big neighborhood, you will probably not lack for work. People that have copyrighted works need to be aware that there are differences in the copyright laws in some nations. While it is true that the United States has signed treaties with some nations, your work will not be protected in every country of the world. As stated, the United States is a member of the Berne treaty. In addition, the United States is a member of the WIPO Copyright Treaty. This treaty works in conjunction with the Berne treaty yet it also covers and gives protection to databases and computer programs. If you would like more information on international copyright law you should check with an attorney who specializes in international copyright law.

Clean Up your Digital Profile and Land that Job Whether you are looking for a job after getting fired or you are looking for a job other than the one you are working at currently, many steps in that process are the same. You need to get your résumé up to date and conform to newest standards, you need to get your wardrobe together and most of all you need to be prepared to go for the interview. But did you know that in a fast paced society with all the high technology gadgets, employers and companies appreciate a good digital profile? When it is time to land a new job it is time for you to clean up your digital profile. For those of you who might not know what a digital profile is, let’s reminisce about digital profiles for just a second here. A digital profile is any and all information about you that can be found online. It can be anything from your own homepage, over articles and answers that you have posted on the Internet to videos and pictures of you. Anything that is somehow connected to you and your name and can be found through Internet search engines such as Google, Yahoo and other crawlers belongs to your digital profile or e-portfolio. Believe it or not, many employers have started to check out your digital profile online by doing a little research on the Internet and finding any information about you. If it is on the Internet it is public information and therefore not illegal. Information on the Internet does not necessarily have to be positive. What if one of your friends posted some stories or pictures/movies about you on the Internet? Employers might see that and think that you are not fir for the tasks that are asked form you by the new job and might just plain throw your nice résumé into the trash before they ever have a chance to meet you in person. Therefore before going onto your next job-hunt, clean up your digital profile. Steps you can take to clean up your e-profile are many and one of the easiest ones is a regular search with different Internet search engines about things that are related to your name. See what comes up and try to clean it up. If there are pictures or movies posted on such pages as u-tube about you, try to get friends or the owners of the page to take them down or at least take your name of the page in such a way that a search engine cannot find this information when somebody is searching for your name. A very important positive step in cleaning up your digital profile is to create your own positive statements and information on the Internet, such as online résumé, Personal web pages or a personal development plan (PDP). If the amount of positive information, academic achievements, and plans for the future are greater than any negative amount of information they can find, the light shed on you is of good nature and your chances are greater to land that job than when they only find negative information for the reasons that you never knew about a digital profile. Should you still be new to all of this and you are not quite as well versed on the Internet, there are places that can help you. Many Universities and development centers offer help and tools just for this kind of situation. Public libraries also offer you free time on the Internet as well as other resources in connection with the job-hunt and digital profiles. So before you actually send out your résumé, make sure that you checked online for any information that might harm you.
