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 Makings of a Magazine: Do They Include You? (writing magazine articles) Magazines are everywhere. They are published on nearly every subject you can imagine, in duplicate and triplicate and more. All that a start-up magazine needs is a niche and an audience. While there may be hundreds of cooking magazines out there, a new one could come up if it should cover cooking for your pets. In fact, there may already be such a magazine in existence. The niche is cooking for pets. The audience is those people who want the healthiest foods for their pets and are willing to put the time and effort into making it for them. If you are interested in writing magazine articles, you?ll be sure to find one that is perfectly suited to your interests and abilities as a writer. Because there are so many magazines, it won?t be difficult to find one that you will enjoy becoming a part of. What You Should Know Magazines survive on advertising. The advertisers pay because the content is good enough that readers will invest in the glossy covers again and again. The best way to find a healthy magazine is to look through the racks for thick publications. They will only be full of content if they are full of advertisements. The big magazines can afford to pay their writers more, but they can also afford to pay only the best writers. Even though there is quite a lot of space to fill with content, you may have a hard time getting published in major magazines at first. Smaller magazines do not have quite the readership and so they also do not have quite the advertisement content. The space will be limited and the pay will be lower, but these magazines will be more open to new writing talent nonetheless. The More You Know, the Better When it comes to a writing career, the more you know the better off you will be. It is not hard to figure out that you will have the best chances for publication if you can write on a variety of topics. You should not limit yourself to a small area of expertise. Work to become an expert in every topic you come across. There is no possible way of course to be an expert in every area of human knowledge, but it will help you in writing magazine articles to learn every new piece of information that you can. For example, if you were to send a query to a health and fitness magazine about writing a short piece about general mountain biking tips they may accept it. They may also then request additional information about the pros and cons of using a road bike on mountain trails. If you only know about mountain bikes, you?ll be stuck. If you have worked on broadening your horizons though, you?ll be able to produce the work that the magazine editor requires. Getting On Staff Querying magazines is a way to get published, but if you need a more stable job, you may be interested in getting on staff with a magazine. Writing magazine articles is a talent. If you can consistently bring an editor what he is looking for, you might have a chance. To improve your chances, in addition to writing effectively, it will help to have some significant education behind you. If you are serious about making it to the masthead of your favorite magazine, it?s time to go to school. A degree will help your credibility as a writer and will help you open doors into the magazine publication world. Writing magazine articles takes a special kind of writer. You have to have a feel for what people are interested in reading about. The magazine content will help you understand how to write for a particular magazine and audience. You can also improve your chances of writing accepted articles by improving your knowledge base. Don?t be picky about what you?re willing to learn and you could go very far in the writing business. Can Facebook or MySpace Help You Land a Job? The Internet is quickly becoming the vehicle of choice for people looking for a job and for employers looking for people to hire. There are many job sites on the Internet dedicated to matching up employees and employers, and most people turn to the Internet today when they are hunting for a job instead of turning to the classified ads in the local paper. Job hunting websites may all be well and good when you are looking for a job, but what about social networking sites. Everyone knows how popular sites like Facebook and MySpace are online, but can they help you get a job? If you are in the job market, can these sites be your foot in the door, or a one way ticket to the unemployment line? The answer is that there is no easy answer. To know if you can find a job using Facebook or MySpace, you have to know how employers feel about these sites, and employers have mixed feeling about them. Some companies are actively using social networking sites to track down employees that meet their company?s employee profile and have had great success finding workers via social networking sites. Other companies wouldn?t touch these sites as a hiring tool with a ten-foot poll ? in fact, many companies don?t even want you to access these websites from their company computers. The real answer to this question has more to do with exactly what kind of job you are looking for. Are you looking for an executive position at a company? Then stay off of the social networking sites, at least for job hunting (and maybe all together). No company is going to look for its top brass on a social networking site, and you will be wasting your time. However, if you are looking for entry level or hourly wage work, the social networking sites like MySpace and Facebook may be the answer for you. Many hourly wage employers in particular, like fast food restaurant chains and mall stores, use MySpace and Facebook to look for potential employees in their area. If a potential employer sees your profile and thinks you may be a good fit for their company, they will send you an email or an instant message and get the ball rolling. You should also, however, carefully consider the downsides of using social networking sites as a job tool ? and you should carefully consider how and if you use these sites at all if you are in the market for a new job. Most people wouldn?t want their parents to see their social networking site profile, let alone potential employers. If you have rude and off color material, political or religious material, and inappropriate photos of yourself on your profile, a potential employer will be turned off, and you might lose your chance at that job. Most people give up way too much of their privacy when they use these kinds of sites, and your social networking site profile may offer a window into a side of you an employer might not be overly impressed with. Further, you can open yourself up to danger by using these sites to job hunt. If someone approached you in the street and offered you a job, would you accept? Then why would you accept a face value an approach by someone on social networking site? If you do get approached for an interview, never meet anyone in a private place, and do your homework to make sure the facts check out before you go for the interview. One last reality check ? there are over 60 million users on MySpace alone. How will an employer find you in the crowd? MySpace and Facebook may help you in your job hunt, but don?t count on them as your sole avenue into the job market. |
