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.

Great Sources for Free Games on the Internet The Internet is a great source for games, especially of course computer games. Computer games are the biggest hit since they are invented and every year thousands of PC games flood the market. Some of the computer games actually are so expensive that many parents cannot afford them for their children and are looking for alternatives that their children can play. There are actually a vast number of games that are available for free through the Internet and in some cases even as a CD. Freeware, shareware, trial products and even full version of prototypes are available on the Internet. Many pages on the Internet actually specialize in offering freeware or shareware programs. Hobbyist programmers usually write shareware and freeware programs and other programmers, who want to give something back to the community. These programs are not always working one hundred percent and most often there is also no real support for all the programs, but they are free. Freeware in general is a free program that has a copyright. The program is made available free for use, but it cannot be changed or used for development by other developers. Shareware programs are often only free for certain periods of time. After that period the user has to pay for using the software. Shareware programs are a marketing method of big computer firms. It is the try before you buy strategy that is used here. Some companies will offer the full version of the program for 30 days for trial, while others offer a version of the program with reduced functions to give the user a taste and to lure the user to buy the product if he wants to use the rest of the functions. Even thougfh both freeware and shareware are often callled free software, free software is something completely different. Free osftware are programs that are available for free, but generally are also avialble for others to study the code, change and modify or even use the code as a base for their development. In any way, these three major types of free game software can be found on the Internet along with such things as online games. Some of the games can be plauyed online. Evne though the userm ight not own the software, the games can be played for free anytime. The only thing that most of those free onlin game pages require is to sign up to their page for free.
