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.
Writers Block: What Causes it and How to Overcome it (writers block) If you are a writer then you know what I am talking about. You have everything ready, a drink, a snack, the topic, and even reference material. You sit down ready to start typing or writing, which ever you prefer, and it happens. You are stuck, your mind is blank and you have no idea how to fill that blank canvas in front of you. It is a writer’s worse nightmare come true. You have writers block. First you need to figure out what is causing it. There are a multitude of things that can be causing it. Stress is one of the biggest factors that cause writers block. Whether it is stress caused by personal matters, deadline dates, or fearing your article won’t be good enough it can block the words from flowing as easily as the should. Sleep deprivation doesn’t let your mind function to its full potential. Getting a good night’s sleep is imperative to having a clear mind and being able to focus. The project itself could be causing the writers block. A topic you are not interested in can easily turn your normally resourceful mind into jelly. The research on that topic turns into a grueling task. Then trying to put the words on paper that make sense and will peak someone’s interest seem impossible. If a topic has personal meaning to you it can be hard to write objectively about it. A simple informative topic can easily become a personal rant session. Writing because you have to, not because you want to makes it hard to concentrate and focus. Now that the basic causes have been covered, you need to know how to fix it. Writers block is not permanent. Identifying the reason is the hard part. Relax. The world is not going to end if the article isn’t as perfect as you feel it should be. Just because you don’t think it is perfect doesn’t mean someone else won’t. Go and read some of your previous writings. Even if what you read has nothing to do with your current topic, it can be inspirational to you. Don’t burn yourself out on a topic. Try to split up the writing process. Research and brainstorm one day and write the next. This will give you time to think about your topic and figure out the angle you want to write. Talk your way through it. Call a friend or colleague and chat. Tell them the topic you are working on and get their opinions or ideas. They may be able to offer fresh insight and ideas. Work on multiple projects at one time if you can. Bouncing back and forth between a few topics can keep your mind hopping and will keep boredom at bay. Take a break from you current project and write about something that motivates you. Chances are once you get those creative juices flowing they will continue into your next project. Make yourself a schedule and stick to it. If your schedule says 500 words by noon, write your 500 words and stop. Even if you don’t have a project going, by writing daily you will stick to your schedule and keeps your imagination going. If you write from home, which most of freelance writers do, make a quiet time and treat it like a real job. If you have young children at home, write while they nap. Let your answering machine be your secretary. If it is important they will leave a message. Most importantly remember why you started writing in the first place. Even the best of the best have gotten writers block at one time or another. US Copyright Lawyer What can a US Copyright Lawyer Do for You that Others Can’t? First a US copyright lawyer can help anyone that is in the United States, they know the laws of the land and the best ways to fight them. A US Copyright Lawyer is here to protect you. That’s right I said YOU, not the neighbor down the road, or someone that lives in the next country but YOU. A US copyright lawyer is there to help you actually file a copyright, advise you and to help you get back what was once yours and sue someone. If you are an American or someone currently living in the United States you will be able to hire a US lawyer, however if you reside out of the states there may be restrictions. In the internet world copyright issues are becoming a big thing and having a US Copyright lawyer behind you can definitely help if you need to fight against someone stealing your work. Copyright lawyers must stay current in all the recent rulings dealing with copyright issues, which means they know their job. Don’t just stick with a lawyer you already had because you’ve used them before. They may have been great at your car accident or your divorce but for copyright issues, you need a lawyer that deals with them. A US copyright attorney can also help you in retrieving money even if you never filed the copyright until after it was stolen or online. This can get a bit tricky when it comes time to prove it though, however if you have a good lawyer this shouldn’t be a problem. A US copyright lawyer will be able to help you copyright any work that you may have, it does cost $20 to file a paper to get the copyright on your work. This does not mean that there is a one time fee of $20 and all your work is safe, actually you must do this with all your work. You are paying per piece, but in the long run if you need to sue someone for using your content they can end up paying $35,000. A US copyright lawyer can help you with this if you live in the United States and the case happened in the states, technically they could help even if it happened internationally but things get a bit more expensive when this happens. Your US copyright lawyer may have already dealt with people stealing content, or maybe celebrity pictures. Recently a big name celebrity had her pictures leaked on the internet, she sued the people that were spreading them and it suddenly stopped. All those websites that had the pictures on them were asked politely to take them down since they were copyrighted and they were gone. That’s what a good US copyright lawyer will do; he/she will be able to prove their case because they know the law. They will have to show proof of when something was taken, said, or documented. In the case of pictures, she was able to show that she had the proofs and that there was no agreement for anyone to use them. Copyright laws have been changing since 1976; however it changes as our technology advances. Lawyers and judges know our needs and are learning every day how to protect them and in order to do that laws are passed and the copyright laws are updated. Granted laws may be different in other countries but the chances are if it happens on US soil, the best representative would be a US copyright lawyer because they have been studying ever since law school. |
