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.
Writing on the Fly (freelance writing jobs) Writing is a fascinating way to explore the world. You can write in your free time about anything you wish to know more about. You may write fiction in order to delve into abstract topics of your world. You may also choose to write poetry to take that concept further. Non-fiction writing will help you understand more objective topics in order to have a clearer picture of the natural and created world. Writing is enjoyable and aids in learning, so what if you could enjoy yourself and get paid for it? This is not to suggest that you quit your job and become a writer, though you could do that as well. The possibilities in freelance writing jobs can give you the flexibility you need to write for money in your spare time. Defining Freelance Writing Freelance writing is writing that happens for an employer without any long term contract. Freelance writing jobs are very different from your typical day job because the trade off for labor and pay does not function in the same way. Freelance jobs are accepted one at a time. There are many different employers that seek out freelance workers. The writer will have the ability to produce a quality product in a desirable amount of time. The employer usually pays based on production rather than hours or weeks. Freelance paychecks come in irregularly, based on the work available. The great benefit to being able to freelance is that you basically get to work for yourself. You can work as much or as little as you wish, only being limited by the freelance writing jobs being offered. As you continue to write, your qualifications will continue to be more impressive. Where are the Jobs? So, maybe you’re interested in finding some freelance writing jobs. The potential to work on your own time, doing something you enjoy and getting paid for it is an appealing one. Where do the jobs exist? There are a few places that you can start looking. A great place to start, to find out what the job market looks like, is the internet. Many employers advertise freelance positions online. They are looking for people all over the country, and potentially all over the world that can work from a distance. Another great benefit to freelance work is that it can happen anywhere. No matter where the hiring company is, the freelance writer can participate in the production of the needed product. Magazines and newspapers both hire freelance writers. In order to find those jobs, it is often appropriate to query the publication in question. First you need to find out about submission guidelines and then send in an article idea. If it is accepted, you are on your way to even more freelance writing jobs. What Does It Take to Be Good? What it takes to be a good writer is not in question. You all know about grammar, style, voice and coherency. What does it take to be successful in the freelance writing category though? There are a few things to consider. First, you will need to be able to be flexible. You may not always be able to write on subjects that you are necessarily interested in. In order to build your resume though, and be able to pick and choose your work, you will have to start out doing whatever needs to be done. Second, to be a great freelance writer, you need to be able to work quickly without sacrificing quality. Oftentimes freelance assignments will go out last minute. You will have a better chance of success if you can honestly take assignments and get them turned in again by deadlines. Finally, a good freelance writer is able to market his talents. The most effective way to prove your writing talents is to introduce yourself in your resume and cover letter in a way that impresses prospective employers. No one will believe you are a writer if you cannot write an engaging cover letter. Freelance writing is a fun way to add a little income to your current pay. It is possible to make a career out of freelancing, but it is not for everyone. If you are interested in writing and want to try your hand at a few different kinds of projects, consider freelancing for awhile. 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. |
