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.

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.

Making Effective Web Publishing Content (web publishing content) Web publishing content is important for a successful website. The content of a web site can often make or break that site, and it is important to make the site as attractive as possible, without over doing it. The content of a web site must be updated on a regular basis to keep web surfers coming back. Updated web content not only keep surfers coming back, but is also indexed more frequently by search engines. Fresh material is one of the key aspects of successful web publishing content and may generate fresh faces to a web site. One way to update the content of a web site is to update the existing web pages. Providing new content could include updating the conditions of a service, adding a new product or service, or creating a turnkey solution that will save the customer’s money or time. The web content should reflect the most recent information about a business. It is simple to provide changes to the web content, but many web sites provide updates without providing a notice. So, it is indicative to provide a notice of change each time web publishing content is changed. The announcements should be displayed prominently on the web site so that all surfers are able to see. It is also important to write articles for the web site. Articles can be seen as a valuable source for a web site’s success. The articles can be used to educate visitors on the web site and the business, while showcasing the owner’s expertise. Articles can be posted on the web site or used in a newsletter and submitted to other newsletters and web sites for syndication. This web publishing content can be used by other web site owners, which will provide leverage to the articles while generating publicity for the author and the author’s web site, while exposing them to new audiences. Writing an article seems simple enough, but there are many web site owners who are unable to find topics to write on. However, topics may be more evident than most web content writers may think. Topics for articles can be found in the news, in conversations with clients and colleagues, in networking events that are attended, and even in speeches. Blogging is also an excellent way to expand your list of web publishing content. Most web site owners can benefit from learning to blog, learning to start a blog, learning how to gain readers, and learning to make money from blogs. Blogging is becoming one of the most popular tools for showing new content on a web site. A web log can be used to answer web site visitors’ questions, inform users about new services and products, and to keep them up-to-date on industry news. Blogs are a great resource for sharing opinions and displaying expertise. The blog can be used to help an owner connect with their web site visitors while generating new web site content. Updating web publishing content on a regular basis is vital to the success of a web site and very important for many web site owners. Articles, newsletter, and blogging should be a part of a regular business schedule, and will work perfectly in keeping a web site owner connected to their visitors. The quality of the web content on a web site can make it more attractive to users or can make it very unattractive to users. Owners should use their expertise to provide writing that is interesting and necessary. Visitors will appreciate the extra effort and owners will get the rewards of maintaining good web content for their users.
