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.

How to copyright music How to Copyright Music for the Beginner For those wondering how to copyright music the answer can be both long and short. The first thing to remember is that most people are confused about exactly what it means to actually copyright music. Music is actually copyrighted as soon as it is presented in a fixed form. It doesn't really matter whether that fixed form is as written sheet music or as a recording. Most people are looking for solid legal protection and while a copyright is good to have, it is essentially worthless unless you've actually gone to the effort of also registering your copyright. Rather than asking 'how to copyright music', perhaps the better question would be 'what do I do now that I've copyrighted my music?' It doesn't really matter what you call it unless you're moving around in legal or industry circles I suppose, but I've always felt that it's a good idea to have a clue about the process in which you are embarking. Now that we've answered how to copyright music, it's time to move on to the real issue, which is registering your copyright. Music is registered through the U. S. Copyright Office. You will need to fill out an application, pay a fee, and provide a copy of your music. As far as government dealings go, this is one of the least painful. Even the fee is marginal when you consider your 'hopeful' future profits and royalties. All that aside, there is something that is massively satisfying about knowing how to copyright music and having your first piece of music registered. Music is an art form and the ability to write music is nothing insignificant. It is a real talent that is actually quite rare. Many popular musicians today use music that has been written by others either in addition to or rather than music that they have written themselves. Even if you aren't a talented performer, it doesn't mean that your music will never be seen or heard or that you should not bother learning how to copyright music. You just might find that you are more in demand for your particular talents than you would have ever dreamed possible. The big thing to remember though is not to sit around wondering how to copyright music but to get out there and go about the process of creating and making more wonderful music to share with the world. It takes all kinds of music to keep this world turning and there is someone out there that is waiting to hear the music that you create. The process of how to copyright music is completely free. The process of registering your copyright is worth every penny you will spend. It is important to protect your music now more than ever with piracy and widespread downloading providing significant reductions in profits for everyone involved. The music industry is also a very fickle industry and you need to maximize your profit potential and usefulness. Once you understand how to copyright music, you need to make sure every piece of music you have has been copyrighted, then you need to go through your music and systematically register each and every piece as well. Even if you must do one piece at a time until you manage to register the copyright on them all, it is much better to be safe than sorry should you ever go to trial in a copyright infringement case. Also remember to pay it forward and support up and coming musicians by sharing the information of how to copyright music and how to register copyrights as well.

Web Hosting - Managing Disk Space Few things are less exciting than managing the disk space that always seems to be in too short a supply. But few things are more important to the health and well being of your site. The most obvious aspect of managing disk space is the need to have enough. If you have only a few dozen web pages, that's not an issue. But as the amount of information (web pages, database content and more) grows, the quantity of free space goes down. That's important for two reasons. All permanent information on a computer is stored on hard drives. Temporary information is often stored in memory only. The two components are completely separate, though they are sometimes confused with one another. As the amount of free space on the hard drive decreases several effects occur. Here's one way to picture them... Imagine you had a table with a certain area and you lay out playing cards on the table. At first, you lay them out in order, the 2 at the side of the 3, then 4, and so on. But then you pick up one or two cards from the middle and discard them. Then you add some more cards. Pretty soon things look pretty random. Now cover the cards with a big opaque sheet of paper. You want the cards to appear in order when displayed to someone. A special robot could be designed to always pick up the cards from underneath the sheet in order. Or, it could slide a hole in the sheet over the cards to display them in the correct order (2, 3, 4, ...), no matter what order they are really in. That's similar to how the operating system always shows you information in a sensible way, even though it's actually stored randomly. Why should you care? Real files are stored in pieces scattered around the drive wherever there is space for them. The more free space there is, the quicker the operating system can find a place to store a new piece. That means, if you delete the junk you no longer need (and free up more space) the system actually runs quicker. It helps create space you might need, and allows the operating system to store files for you faster. But there's a second effect. As you delete old files or change them, the pieces get more and more scattered. It takes the 'robot' longer and longer to fetch or display the 'cards' in order. Existing files are fetched and put together 'on the fly' (say, when you request a graphical page or a list of names). But, it takes longer to put together the web page when there are more scattered pieces. So, the other aspect of managing disk space is to keep the pieces of the files more or less in order. A utility that does that is called a 'de-fragger' or de-fragmentation program. You can request that a system administrator run it, or if you have the authority, you can run it yourself. That keeps the 'cards' in order and allows for quicker access to them. So, managing disk space involves chiefly three things: (1) keeping enough space to store what you need to store, and also (2) keeping enough free space to make new file storage quick and (3) making old file retrieval fast by keeping things orderly. When only a few files are involved the benefit isn't worth the effort. But as the number and size of the files grow, to thousands of files or several gigabytes of data, the effect becomes more noticeable. Keeping things organized then makes a significant difference in performance. Much of this can be automated using utilities. Some will delete files in a certain folder older than a certain date. A de-fragger can be set to run automatically during times of light usage, or quietly in the background at all times. Discuss the options with your system administrator and help him or her do the job better by keeping your house in order. You'll benefit by having a better performing web site.
