Web Hosting - Domain Name Changes and How They Affect You New domain names are registered all the time, and ones previously registered expired. Sometimes that's the result of simple neglect. The owner of the name chose not to renew his or her ownership, so the name became available for someone else to use. In rare cases, a highly original mind managed to think of a new one. In the other common scenarios, someone chose to just let it go or sell it. When you choose to change your domain name, there are actually two separate steps involved: releasing the old name, and adopting the new one. But, just as the postal system can have difficulty forwarding your letters when you change your personal name, changing your domain name brings certain difficulties. One of the most prominent is the fact that any name change requires a change to thousands of DNS Servers around the globe. DNS (Domain Name System) is the set of software/hardware components that allows domain names to map to IP addresses. IP addresses are what are actually used 'under the covers' when one computer communicates with another. Note that there isn't always a 1:1 correspondence between a name and an IP address. One IP address can serve multiple domain names and one domain name can have multiple IP addresses. For the sake of simplicity, we'll stick to the common case here. DNS servers around the world maintain internal databases that match the name to an IP address. Not all servers have all pairs of names/addresses. A series of complex routines allows a request to be forwarded when the particular DNS server doesn't have a needed record. When you acquire a domain name that used to be associated with a given IP address, the odds of you acquiring the same IP address are extremely low. In the unlikely case, for example, that you acquired the domain name yahoo.com, you would almost certainly not get the IP address that was matched with it (unless you bought the Yahoo! company). So, as a result of the change, the name/IP address pair is no longer what it was. A similar circumstance exists when you retain your IP address, but want to change the domain name associated with it. In either case, the pairing has changed. The catch is this: when the change takes place, those DNS databases are not all updated instantaneously around the world. Even apart from the limited speed with which computers and networks operate, (and neglecting the human factor if/when the change is made manually to more than one server) the reason is something called caching. In order to communicate efficiently, DNS servers are designed to assume that changes will be relatively rare. Just as with the postal system, you don't move your address or change your name every minute. Since that's true, in general, the name/IP address pair is cached. A cache is a set of stored information that is reused so that fresh information doesn't have to be communicated with every request for a web page or data. A chain of DNS servers pass requests to the last known address. There is usually more than one system between your computer and the server you want to communicate with. Most of the time, that's your current name/address. When you change the name, that pair is no longer valid. In order to propagate the new name/address pair (so the terminology goes), that cache has to be refreshed. Something similar happens when you establish an entirely new name. That name is first associated with an IP address and that pair has to be communicated to DNS servers around the world in order for you to be able to reach any one of them at random. But DNS servers don't do that until they are requested to do so by your action of asking for information from a remote server. Because of that, but chiefly because of caching, it can take quite a while for the new pair to become known around the Internet. Caches can expire and get refreshed in a few minutes or a few hours. It varies. That time can be as short as an hour or less, if the path between your computer and the web server is very simple and only one DNS server needs to be updated. Or, it can take up to 48 hours or more. Though the 'official' range is often given by registrars as 24-48 hours, the average is closer to about six hours. But that's an average. The actual time in any given case can (and does) vary widely. In the meantime, a number of effects can occur. The most obvious is that, since the name/IP address pair can't be resolved properly, you don't reach the server you want. Your browser points to the old one (in the rare case it's still accessible by that name and address), or it simply reports there's no such name at that address. So, when registering a new name or buying an old one, you should establish the site, but not advertise it for at least a couple of days. Better to wait to get visitors than to turn them off by being 'not at home' when they call.

The Importance of Written Communication (written communication) Written communication is just as important as oral communication. Of course, all communication requires a clear concise flow of ideas, and words that are easily understood by any reader or listener. Written communication is one of the most difficult forms of communication as writers are typically prone to write for themselves, instead of for their audience. It is important for readers to understand what has been written and why it has been written. Writing is very different from oral communication, because words are written they cannot be taken back. Communicating through writing is more concrete than verbal communication with more room for mistakes and misunderstandings. The slightest misunderstanding can cause chaos for many, so it is important to right as clear and concise as possible. This form of communication is defined as a clear expression of ideas in writing. The clear expression of ideas includes grammar, organization, and structure of an essay, book, article, or report. Grammar is a large part of written communication, and writers must always consider spelling, punctuation, writing style, and wording before displaying their work to the world. Proper grammar and form may have a varying importance for different writing jobs, and usually depend on the method of communication used for that job. However, it is always important to strive to use correct grammar, spelling, and punctuation. Most writers use spell check and grammar check on their computers to ensure that the grammar and spelling is suitable. Grammar is also a major factor when writing as a freelance writing and submitting work to an editor. Many editors will reject further submissions from writers who have too many grammar and spelling errors. Organization of a letter, essay, article, or book is also important factors of written communication. Communication should always have a logical organization that is easy for readers to follow. For the reader, it is much easier to read a paragraph with one common theme that relates to the entire work. Most writing requires a clear flow of ideas and proper transitions to indicate when a new idea is being presented. However, transitions are not often needed for pieces of writing that are clearly organized. Ideas should also be expressed in a manner that is easy for the reader to understand and recognize. Data in the writing should also be presented accurately to support conclusions and recommendations given by the writer. The structure is also important in a piece of writing. All writing is organized into five to seven sentence paragraphs that all relate to each other. The number of paragraphs usually depends on the work that is being written. For example, it is common for essay to contain five concise paragraphs that all relate to a common theme. Generally, essays begin with an introductory paragraph, followed by three supporting paragraphs, and ended with a concluding paragraph. The basic structure of a piece of writing is only the beginning of written communication; the words used and the organization of the work is important to the readers understanding of the work. In many cases, the style format, and content must be adjusted to the communication level of the reader. The ability to convey ideas to a certain reader are very important, and a key component of written communication. Like oral communication, written communication can be seen as an aspect of life that makes the world go round, and learning to communicate through written word has become a basic skill for most people. Communication is needed in all aspects of life, and although many people cannot write well, it is important to be able to communicate out loud and on paper.

Positive Reasons Why Employee Turnover Can Be a Good Thing Employee turnover is the bane of many an organization. If you pick up any business paper, you will find headline after headline screaming about how much turnover is costing companies and how to keep your employees happy and on board to avoid the headaches and hassles of high turnover. The tide, however, is starting to turn. More and more business experts are stepping up and saying turnover doesn’t have to be the end of the world. In fact, in some cases, turnover can be the best thing that ever happened to your company. While some turnover is as bad as traditional wisdom assumes it is, other instances of turnover can be a real positive for your business. How can turnover possibly be a good thing? It all comes down to who is leaving the company, and why. Every office has its workers that are a drag on the business for one reason or another. Maybe the employee is dissatisfied with their job because they have been working it for too long and are overqualified, but they don’t have any room for advancement. Maybe an employee thinks that all of the decisions you are making about the business are the wrong ones and are constantly critical. Maybe the employee just has a personality conflict with the other people in the company and you and other works simply don’t like them very much. When these kinds of employees leave your company, it can be a shot of life into the business. Suddenly, everyone feels hopeful and re-energized because the negative energy in the air is gone. Negative vibes in the office can have a very damaging effect on the staff, and by extension, your business. When the person causing the bad feeling heads for the highway, they take with them all of the problems they created. Not only does the departure of an employee who was causing trouble in the office boost morale for the employees who are left behind because the bad feelings are gone, but it also boosts morale because it creates a job opening within company. If the person who left was a superior to many people in the office, there is now an instant opportunity for advancement. Your workers will step up with their games as they vie for the position, creating new business opportunities for you and generally keeping the spirit high in the office. If you decide to promote from within whenever possible after a turnover, your employees will work harder with the knowledge that they have a chance of moving up. These turnover positives hold true whether the employee in question quit the job or was fired. Who they were in the company and why they left are often much more important in determining whether the turnover was positive or negative. While losing an employee who is bringing everyone else down is a positive thing for your business, losing an employee who was an integral part of the corporation is another. Of course, there are costs involved in a turnover – you have to re-train an employee, and if you hire from outside of the company, you have the costs of advertising the job and the cost of the time spent interviewing candidates. If you are losing employee after employee, and the employees you are losing are the ones who were holding things together at the office, then you need to consider things you can do to reverse the turnover trend. Despite the potential negative side, turnover doesn’t have to be a bad thing for your company. If you manage it properly and if you are dropping employees who have been bringing your business down, turnover could be just the thing to turn your fortunes around.
