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.

Education Copyright Law The Nuts and Bolts of Education Copyright Law It is a wonderful thing that Education Copyright Law is available for educators. It isn’t only teachers that can take advantage of education copyright law. Students are also covered under education copyright law -- to a degree. Teachers are able to use copyrighted materials in their classroom and make copies of them. Students are also able to use copyrighted materials in school projects. The key to education copyright law is how often a teacher or student uses copyrighted material, in what way they are using it and how many copies they have of it. It is important that teachers and students do not cross the line of education copyright law or they could be in for some stiff penalties. It helps many students and teachers to learn what exactly is not copyrighted. Any work that is in the public domain is not copyrighted and can be used in school and for school projects. Work that is not in the public domain is copyrighted and if you use it you should make sure you fall within the fair use or education copyright law regulations. Many people do not know what exactly fair use copyright regulations are. When you are trying to see if you can use another’s words, you should keep a few things in mind. The answer to the following questions will help you gage whether you would be violating a copyright. First, are you transforming someone else’s work or are you copying it directly? If you are using another person’s work directly, for what purpose and how much of the original author’s work are you using? Many publishing companies have set rules on how much material they will allow to be quoted in other sources. Some of these ranges start at 100 words or less. However, there are truly no standards to go by, so be careful. You can not assume that keeping your copying fewer than 50 words will allow you to pass under the radar – especially if the original piece is hovering around 125 words itself! There is a greater amount of room to maneuver when it comes to technical writing. For instance, if you are writing a report on something that involves a lot of reporting from an expert, you would probably need to quote more of their work than you would a fiction novelist’s work. The fair use copyright law enables people to use portions of material that is copyrighted for the purposes of criticism or as commentary. Individuals who are involved in the distance education field should take a look at the TEACH Act that was made into law in 2002. This Act clearly outlines the requirements that a university or school must be in compliance with when it comes to transmitting copyrighted works via the Internet. The TEACH Act allows students and teachers to transmit copyrighted works, but they must be within certain guidelines. If the school or university cannot meet these guidelines, the material that is being transmitted via the Internet needs to fall within the fair use copyright act – or the individuals involved need to have permission from the copyright owner. If you are an educator and you are using copyrighted material make sure it falls within the education copyright law.
