Web Hosting - The Internet and How It Works In one sense, detailing the statement in the title would require at least a book. In another sense, it can't be fully explained at all, since there's no central authority that designs or implements the highly distributed entity called The Internet. But the basics can certainly be outlined, simply and briefly. And it's in the interest of any novice web site owner to have some idea of how their tree fits into that gigantic forest, full of complex paths, that is called the Internet. The analogy to a forest is not far off. Every computer is a single plant, sometimes a little bush sometimes a mighty tree. A percentage, to be sure, are weeds we could do without. In networking terminology, the individual plants are called 'nodes' and each one has a domain name and IP address. Connecting those nodes are paths. The Internet, taken in total, is just the collection of all those plants and the pieces that allow for their interconnections - all the nodes and the paths between them. Servers and clients (desktop computers, laptops, PDAs, cell phones and more) make up the most visible parts of the Internet. They store information and programs that make the data accessible. But behind the scenes there are vitally important components - both hardware and software - that make the entire mesh possible and useful. Though there's no single central authority, database, or computer that creates the World Wide Web, it's nonetheless true that not all computers are equal. There is a hierarchy. That hierarchy starts with a tree with many branches: the domain system. Designators like .com, .net, .org, and so forth are familiar to everyone now. Those basic names are stored inside a relatively small number of specialized systems maintained by a few non-profit organizations. They form something called the TLD, the Top Level Domains. From there, company networks and others form what are called the Second Level Domains, such as Microsoft.com. That's further sub-divided into www.Microsoft.com which is, technically, a sub-domain but is sometimes mis-named 'a host' or a domain. A host is the name for one specific computer. That host name may or may not be, for example, 'www' and usually isn't. The domain is the name without the 'www' in front. Finally, at the bottom of the pyramid, are the individual hosts (usually servers) that provide actual information and the means to share it. Those hosts (along with other hardware and software that enable communication, such as routers) form a network. The set of all those networks taken together is the physical aspect of the Internet. There are less obvious aspects, too, that are essential. When you click on a URL (Uniform Resource Locator, such as http://www.microsoft.com) on a web page, your browser sends a request through the Internet to connect and get data. That request, and the data that is returned from the request, is divided up into packets (chunks of data wrapped in routing and control information). That's one of the reasons you will often see your web page getting painted on the screen one section at a time. When the packets take too long to get where they're supposed to go, that's a 'timeout'. Suppose you request a set of names that are stored in a database. Those names, let's suppose get stored in order. But the packets they get shoved into for delivery can arrive at your computer in any order. They're then reassembled and displayed. All those packets can be directed to the proper place because they're associated with a specified IP address, a numeric identifier that designates a host (a computer that 'hosts' data). But those numbers are hard to remember and work with, so names are layered on top, the so-called domain names we started out discussing. Imagine the postal system (the Internet). Each home (domain name) has an address (IP address). Those who live in them (programs) send and receive letters (packets). The letters contain news (database data, email messages, images) that's of interest to the residents. The Internet is very much the same.

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.

Music copyright infringement How Does Music Copyright Infringement Affect Me? Music copyright infringement happens all around us every day, by both well meaning people downloading music from their favorite social networking site to the guy who’s reselling MP3s. To be certain, most people who commit music copyright infringement don’t realize what’s going on, and are in turn doing something very illegal and prosecutable in the United States. Copyright Infringement, as defined by Wikipedia.org states: “Copyright infringement (or copyright violation) is the unauthorized use of material that is protected by intellectual property rights law particularly the copyright in a manner that violates one of the original copyright owner's exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative works that build upon it. The slang term bootleg (derived from the use of the shank of a boot for the purposes of smuggling) is often used to describe illicitly copied material.” We’ve all heard of ‘bootleg’ recordings – usually audio recordings taken from concerts and sold on home made cassettes or CDs and distributed (sometimes out of the trunk of a car) to anyone that will buy. Bootleg recordings have changed, however, as music copyright infringement has branched into video recordings. Music copyright infringement has exploded with the advent of the internet, and now people from all over the world are sharing every type of imaginable file – from eBooks to audio to music – and small label artists began feeling the pinch years ago. However, many new and older artists are beginning to see the beauty of the internet, and are offering their music for sale track-by-track on iTunes and other MP3 sales websites, as well as through their own band websites and MySpace pages. The internet has exploded in the possibilities it’s given up and coming musicians to become visible, while at the same time drastically increasing the number of music copyright infringement cases – some of which were against innocent people who just weren’t informed. Music copyright infringement cases have helped to create organizations that protect the fair use of an item, such as a song. Organizations such as CreativeCommons.com and the Electronic Frontier Foundation help individuals to know their rights under copyright acts. While there are organizations that help you understand your rights as a purchaser of copyright use, there are organizations that want to limit the ways in which you use the products you buy. It is rumored, for example, that record distribution and production companies want to limit the ways in which you use the music you buy – they don’t want you to put it on your computer or make a Mix Tape or CD from it – for fear of ‘sharing.’ It seems to me, however, when music publishers and distribution companies limit uses like this, they’re opening up a tidal wave of music copyright infringement cases. By limiting the use of purchased material, the companies are alienating their client base and pushing all their sales away from physical products and toward electronic ones – which are much harder to control. A way in which these companies tried to limit the uses was by creating a DRM program, which severely limited the where a CD could be played (on one computer, for instance). And, in one drastic measure, Sony placed a DRM program on all their CDs in the Winter of 2005, and severely crippled several networks when their ‘program’ was actually malware that seriously crippled network security. As you can see, music copyright infringement is something that is currently being fought between end users and music production and distribution companies. In this new century, we must find a way to retain copyright, and allow the customers to use the products they buy in a meaningful way, or otherwise the market will shift and the industry as we know it will be abandoned.
