Web Hosting - Free vs Paid Web Hosting Options Everyone likes to get something for free. But as the existence of spam shows, free isn't always good. Sometimes, it's downright harmful. Deciding whether it's worth the cost to pay for hosting involves a number of complex considerations. Hosting companies that offer free services obviously can't stay in business from the money they make from you, since there isn't any. So why do they offer free hosting and how do they make money? Why should you care, so long as you get yours? Because, in reality, there's a price of some kind for everything, even something that's free. Free hosting may come from a company doing a promotion to attract business. They expect to demonstrate their value, then charge an existing customer base fees to make up for what they lost by the (short term) offer. It's in essence a form of advertising. But free hosting is offered by lots of companies that are not dedicated to managing servers for websites. Google, Yahoo and thousands of others provide a modest amount of disk space and a domain name on a server for free. Users are free to do anything they like with it, though if the load becomes excessive you can be shut down. That introduces one of the more obvious drawbacks to free hosting: resource limitations. Typically free hosting offers a relatively small amount of space. That's often enough to host a few dozen pages. But an active site can quickly run out of room. A more serious limitation is load. Free hosting often places strict limitations on the allowed amount of bandwidth consumed. If you become a well-visited site, when users start banging away on the server, you can be asked to leave or simply be blocked for the rest of the month. Or, you may be permitted a certain quantity of total bandwidth use per month. Once it's reached, no one else can reach your site until the beginning of a new month. At the same time, you will certainly be sharing equipment with thousands of other sites. Their load can affect your performance, prompting you to move. Migrating an established site brings with it a number of thorny issues that might be better avoided in the first place. Free hosting has another potential downside: lack of support. When you pay for hosting you typically get, at least in theory, a certain level of support. Backups in case of disaster recovery from a hack or server failure, assistance in analyzing connection problems... the variety is endless. With free hosting you usually get none of that. A company or site that offers free hosting will usually recover a disk or server that fails completely and you'll be back up when they do. But if only selected portions of the drive fail, or you lose a few files through a virus attack or accidental deletion, you have to rely on backups to recover. A free service will usually come with no such option. That may not be a problem if you have a small site. You can make copies of everything at another location and simply recover the site yourself - if you have the discipline to keep it current and the skills to make and restore the copy. Free hosting will typically come with a few email addresses, intended to be used for administration and other tasks. But if your needs grow beyond that, you'll need to seek another option. The email service also comes with minimal oversight. The server may be protected against spam attacks and provide virus scanning. But few free services will provide even minimal help with any issues that arise. But the most serious limitation may have nothing to do with any technical issues. Free hosting services often require that your site's pages carry some form of advertising that pays the host, not you. That may be fine for you, or it may not. Individual circumstances vary. On the other hand, if you're just starting out, a free hosting option can be a great way to learn needed skills and a few of the potential pitfalls. You can set up a site, learn how to maintain and improve it, and not care too much if it gets hacked. Freely hosted sites can be a great platform for learning the ropes. Free services don't usually offer any of the features that an active, commercial site will need sooner or later. So if you plan to grow, it may be reasonable to get the free service for a while, knowing you'll have to migrate when you become popular. But in the long run, you get what you pay for and you may need to pay for what you want.

Web Hosting - Redundancy and Failover Among the more useful innovations in computing, actually invented decades ago, are the twin ideas of redundancy and failover. These fancy words name very common sense concepts. When one computer (or part) fails, switch to another. Doing that seamlessly and quickly versus slowly with disruption defines one difference between good hosting and bad. Network redundancy is the most widely used example. The Internet is just that, an inter-connected set of networks. Between and within networks are paths that make possible page requests, file transfers and data movement from one spot (called a 'node') to the next. If you have two or more paths between a user's computer and the server, one becoming unavailable is not much of a problem. Closing one street is not so bad, if you can drive down another just as easily. Of course, there's the catch: 'just as easily'. When one path fails, the total load (the amount of data requested and by how many within what time frame) doesn't change. Now the same number of 'cars' are using fewer 'roads'. That can lead to traffic jams. A very different, but related, phenomenon occurs when there suddenly become more 'cars', as happens in a massively widespread virus attack, for example. Then, a large number of useless and destructive programs are running around flooding the network. Making the situation worse, at a certain point, parts of the networks may shut down to prevent further spread, producing more 'cars' on now-fewer 'roads'. A related form of redundancy and failover can be carried out with servers, which are in essence the 'end-nodes' of a network path. Servers can fail because of a hard drive failure, motherboard overheating, memory malfunction, operating system bug, web server software overload or any of a hundred other causes. Whatever the cause, when two or more servers are configured so that another can take up the slack from one that's failed, that is redundancy. That is more difficult to achieve than network redundancy, but it is still very common. Not as common as it should be, since many times a failed server is just re-booted or replaced or repaired with another piece of hardware. But, more sophisticated web hosting companies will have such redundancy in place. And that's one lesson for anyone considering which web hosting company may offer superior service over another (similarly priced) company. Look at which company can offer competent assistance when things fail, as they always do sooner or later. One company may have a habit of simply re-booting. Others may have redundant disk arrays. Hardware containing multiple disk drives to which the server has access allows for one or more drives to fail without bringing the system down. The failed drive is replaced and no one but the administrator is even aware there was a problem. Still other companies may have still more sophisticated systems in place. Failover servers that take up the load of a crashed computer, without the end-user seeing anything are possible. In fact, in better installations, they're the norm. When they're in place, the user has at most only to refresh his or her browser and, bingo, everything is fine. The more a web site owner knows about redundancy and failover, the better he or she can understand why things go wrong, and what options are available when they do. That knowledge can lead to better choices for a better web site experience.

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.
