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.
A Brief Guide to Writing Short Stories Effectively (writing short stories) A short story is basically a condensed version of a book or a rapidly progressing story. It has fewer characters than a novel and covers less amount of time. A short story generally is around 6,000 words or 6 pages. Do your research and organization before you begin to write. Outline your plot and the background. Make sure they make sense and flow together. Individually list the events of the story in the order in which they occur. Create your characters. Not just their name and role in the story, but as if they were real people with real lives. By creating more information for your characters you will get a sense of what they would do or how they would be and convey that to your writing. By creating an outline you will have a point of reference to look back upon and make sure you have included all vital points of the story. When writing a short story, you will need a captivating first paragraph. You have roughly 5 to 7 lines to appeal to your reads unlike novels that have the whole first chapter. This can actually make or break your story. You will need to grab their attention and keep it to make them want to read more. By starting the plot in the first few sentences it will make people want to know more. They will keep reading to find out who is involved and why. Keep the timeline of events brief. You are writing a short story and the timeline should match that. A timeline of a day, a week, or maybe even a month is generally the span a story should cover. Use character dialogue as a way to move the plot ahead. In a short story there is no time for general chitchat. By using the character dialogue you are deepening the plot as well as moving it along. Do not add unnecessary characters. By adding them you are wasting time one someone that is not linked to your story or its plot. Provide swift and precise details to keep the story moving. Elaborate descriptions of characters, plot, or surroundings will only waste your words and are not essential to making a good story. Use short words instead of phrases that mean the same thing. Building to the climax should be most of the story. Keep the conflicts building to the climax simple and easy to understand. You writing should be able to evoke the following emotions empathy, pain, hurt, despair, surprise, and desire just to name a few. Since the story is only a few pages long in its entirety it is necessary to maintain consistency through out the beginning, middle, and end. Make sure the dialog and plot complement each other. Keep the same point of view through out the story. You are almost ready to be published. After completing your own proofreading and editing, let someone else read it, a neighbor, your spouse, colleague, or a close friend. Even if they are not writers themselves they will be able to help point out any grammar errors. They will be able to tell you if something just doesn’t make sense. You are trying to fit a lot of captivating information in a small space; it is easy to leave something out. Something you may not catch because you know what is supposed to happen, while your will not. By following these simple rules, you will be able to write a short story that is captivating and effective. Writing short stories isn’t for everyone. Many writers like more detail and for short stories the space is just not available. Freebie Etiquette (Yes, There is Such a Thing!) When you are on the hunt for free stuff, it can be easy to be so blinded by the offers that your manners go flying out the window completely. You may also just not realize that when it comes to taking advantage of freebies there is a general code of conduct that it pays to follow. While you are racking up the free stuff, keep these common courtesy rules in mind so that you are doing your part to keep the hunt for freebies fun and enjoyable. Freebie etiquette rule number one is to remember that there is a face behind every freebie, no matter how distant it may seem. Since so many freebies come from websites and you don’t actually have interaction with a human being while you are getting them, it can be very easy to forget that someone (or very likely, a lot of someones) worked hard to bring you that website and that free deal. If you have a problem with a website or a form while trying to get some free stuff, deal with it as respectfully as you would if you had to approach a customer service rep in person. Leaving foul-mouthed posts on a message board or unloading a barrage of outrage on a customer reply form isn’t the way forward. Someone – a real person – will have to help you, and you’ll get a lot further by treating them with respect. Respect is also the name of the game when it comes to rules attached for freebie offers. There are often restrictions in place for taking advantage of free offers, such as the age you have to be to cash in on the offer or how many offers per household can be taken. Sure, there are plenty of ways to get around these rules and “trick” a company into giving you an offer for which you are not really eligible. However, when you try to simply bleed out as many free offers as you can, you’re only making it hard on companies to be able to keep bringing these offers to you. If this freebie isn’t for you, take a back seat and make room for the folks who can take advantage of it. Your time will come. Related to this last rule is the idea of not being too greedy when gobbling up the free stuff. Just because something is free doesn’t mean you should use a “smash and grab” approach and go for as much as you can get of anything you can get. Remember that there are a lot of other people out there who like to get in on the freebies, too, and think about how you would feel if you lost out on something you really wanted because someone came along and took them all. Don’t take more than your share of any free offer, and don’t take things you don’t want or need just because they’re free. Everyone loses when you do that. Last but not least, if you have an opportunity to say thanks for a freebie, grab it. Of course, this can be hard to do when the free offers you are taking advantage of are found on the Internet, but there are still ways. Look for the customer comment field in the request forms you fill out to get your free stuff and leave a quick thank you there. You can also write a thank you on message boards and chat rooms that are associated with the freebie websites. The good will generated by your gratitude will only help convince companies that freebie offers are useful tools for reeling in the customers. |
