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.
The Slam and Other Outlets for your Poetry Needs (poetry reading) Poetry is an effective display of human life and emotion. Not only are the writer’s feelings about life revealed, the reader is also taken on a journey of meaning and feeling. Poetry is an outlet for writers and readers alike. Each new poem that is written is another chapter in the entire human experience. Since people are looking for meaning within their experiences, poetry draws fans by adding that meaning. Poetry reading can be educational and enjoyable. There are many places and forms that poetry reading can take, so if you are looking for an outlet or inlet of your own, you’ll be sure to find one that will fit your needs perfectly. A Poetry Slam A poetry slam is a gathering of poetry lovers. Each person that attends brings one or several pieces of poetry to read. The poems can be individual work or work that you have come across in your poetry reading. The point is to allow everyone to enjoy poetry that they may have never heard before. As each reader places his own interpretation within his reading, everyone can enjoy the variation in style and sound and meaning that comes out of the experience. There are probably a few poetry slams scheduled in your community already. Check the library or the local college campus for more information. If poetry slams are not already being scheduled, or if they are not frequent enough for your taste, you can start your own. All it takes is a meeting place and some flyers. You’ll probably meet all kinds of people that you enjoy being with at a poetry slam. Going to Class Another place to meet other poetry lovers is in class. If there is a college or university campus near you, join a class. Poetry classes are often scheduled in the evening because of their popularity with those who are not regular students. Poetry reading happens in a couple of different kinds of classes. You can take poetry classes that focus on poetry that has been written through history. Sometimes the classes will focus on a specific group of people or time in history. As the subjects change, you can continue to take the classes and continually come across new poetry that you have not read before. You can also take poetry classes that encourage you to write your own poetry. You will then be able to read your work as well as listen to others’ work. The great thing about poetry classes is that they are set up for discussion. You can discover more meanings in other people’s writing and develop your own with the help of other qualified students as well as your professor. The Impromptu If you are involved in any other kind of poetry reading, you will probably be well immersed in the different forms of poetry. Understanding a few different writers’ perspectives will allow you to involve poetry in your every day life. As you talk to friends and relatives about typical situations that arise, you will be able to bring meaning to many of your conversations through poetry reading. You will probably also develop your own skills of writing and so be able to express yourself effectively when it comes to all kinds of human experiences. Hopefully, at impromptu poetry readings, you’ll be able to inform your friends and relatives as well. Poetry reading opens doors to the heart and the mind. Poetry is a deep expression of emotion and the understanding of life as well as death. Don’t hesitate to broaden your own poetic horizons by experiencing your own poetry and that of others. Try some of the outlets and inlets listed above. What to Think about While Choosing a Writing Desk (writing desk) Writing desks come in many shapes and forms. The technical definition is a piece of furniture with a surface for writing, with drawers and pigeonholes for writing materials and a portable case that when opened forms a surface on which to write. A writing desk could be as complex as that definition or as simple as a desk for writing. Basically a writing desk can be anything that you want it to be. You may not need to buy a writing desk. You may be perfectly comfortable with one you already have or working on the couch or at the kitchen table. This is fine. If it is a cohesive work environment for you that is fabulous, but some writers require a more formal, dedicated area just for them. By finding the perfect writing desk, you are on the way to the start of creative that work style atmosphere that they need. Before you begin your writing desk shopping venture you must first have two things picked out. The area in which your desk is going to go and the chair you are going to use. The location of the desk is important because it will be necessary to choose a size and style. The chair is important for comfort and maybe an important factor in determine the correct height of desk needed. Once these are figured out you shopping journey is ready to begin. While shopping for a writing desk the most important feature is comfort. You need to sit at the desk for most likely for hours at a time. Having a desk at the right height is imperative to this. With the writing surface being to high or to low will not only be uncomfortable but also will more that likely make it difficult for you to concentrate and write. Having a writing desk that is not the correct height is likely to cause neck and back strain. The function and the size of your writing desk are the next factors you need to consider before you purchase one. Do you need one with a little storage or a lot? Does it need to have an adjustable surface or can it just be flat? With all the choices available assessing what you need can help narrow down the ones that will work for you. How big of a space do you have for it? These are some simple considerations that are often forgotten while buying a writing desk. It would be terrible to fall in love with a desk and bring it home just to find out that it is not going to fit. The next important thing is style. When choosing the style of the writing desk you will want it to flow with the furniture already in your home. If your home is modern or contemporary you may want to choose one of the metal and glass desk designs or perhaps one with light wood tones and metal accents are right for you. Another great writing desk available is called the secretary. The secretary is wooden desk with drawers on the bottom and a fold down writing surface. They are usually compact in size but have ample storage and often offer shelving covered by glass doors on top. Plus having a fold down writing surface, it is easy to close up when you are done and hide you space altogether. Choosing the writing desk that is right for you may not seem that important. I mean how difficult could it be to choose a surface to write on, right? But making sure comfort, storage, and style fit into your lifestyle is an important decision. This is part of creating a suitable working environment for you to produce your work. |
