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.
Explaining How Credit Scores are Used in the Hiring Process You might be wondering why credit scores are used in hiring processes. While you may have never heard about it, it is actually a more common practice than you might think. Companies and institutions such as banks, universities, retail stores, financial institutions across the United States use credit scores to determine whether an applicant is good for the open position or not. Even though you might think that this is illegal, it is not. In general, it is a legal undertaking for companies to look at your credit score. This is yet another reason why you should make sure that your credit scores are good and up to date. So why would they be using your credit information in a hiring process? For some of these companies, employees will be exposed to a lot of money and have a financially responsible position. Your credit information can actually help them determine whether you are a financially responsible person or not. Companies think that if you cannot handle your own money, why you would be qualified to handle their money? On the one side, if you think about it, it is a very valid thought. On the other side, the credit history will not tell the company how you might have gotten all the debt. What if one of your family members is really badly sick or a similar situation? In this case, you have not been irresponsible with your money, but you saved a family members life. You might have been willing to take on all this debt and then work from there. Sometimes numbers are just not an accurate representation of your life. Companies that do use your credit are not only determining whether you can handle money, in some instances they use it as an indicator for your character. It will tell them if you are responsible with your money and finances you are a responsible person. A person that will not be tempted by money or certain situations in a workplace is a person they can securely trust with their funds, their tasks or their great projects. One thing is for sure, the company needs to let you know that they are going to check your credit history in their hiring process and they also need to let you know what they are checking for. The criteria they are looking is the criteria they have to tell you about before you give them the permission. Unless they tell you and have a signature of permission from you, they are not allowed to check and use your credit history. If they miss these above mentioned steps, you do have a case in you hands that you can bring to the court. In some instances, some of the people that were not told about the credit check and have been denied have had a good case in their hands. But as with so many things in life in the United States it pays off to have a good credit history and such a check will not ruin your career moves. Check your credit history every year since once a year the big credit companies do have to give you a free credit report. In the case that you find any wrong or dubious items on your account go ahead and dispute them. Oftentimes companies might just have put a claim against your account that is not really caused by you. Why do companies do that? Money has caused many bad things in the world and a company that wants their money back is going to run after any lead they have. Therefore disputing your case and putting your credit score back to normal can be an essential part in your application and hiring process with some companies.

Its purpose is to show a clear understanding of a subject by presenting information. Technical Writing is used in owner manuals, how to guides, magazine articles, and design specs just to name a few.
