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.

Working on Your Own Time: It’s What Freelancing is About (freelance jobs) Do you have a busy life? Do you wish that you could schedule your work around the rest of your priorities? You work to make money so that you can live. You have no choice but to pay for housing and food and other life necessities. Because you need the money, work tends to creep up to the top of the priority list. Other things are more important though. Freelance jobs allow you to put work where it belongs on the list of priorities. You can play with your kids when they’re home, enjoy doing the things you enjoy outdoors while it’s daytime and spend your Sunday mornings at church instead of behind a counter. The work still needs to get done, but you can do it when you have time instead of from nine to five, Monday through Friday or worse, whenever you’re put on the schedule. Kinds of Freelance Jobs Do you have the appropriate skills and abilities to work at freelance jobs? There are many, many different kinds available. Those with professional degrees can consult. While the jobs that result from extensive education generally lead to many hours working for a good salary, your education can lead you in another direction. If you can manage to find the clients, you can work by appointment only, guiding those who do not have the experience or education that you have. If you are not a professional, you may still have the appropriate talents that will get you into freelance jobs. Writing is a very popular freelance opportunity. You live in a world that relies on the written word. You do not go through a single day without reading a considerable amount of text. Someone needs to do all of that writing, and much of it is hired out to freelancers. Actually, any skill that you possess may be suited to freelance work. Check out a few job boards and find out who’s hiring. Tips of the Trade Freelance jobs are out there, but so is the competition. To get yourself to the top of the hiring list, there are a few things you can do. First, use any experience you have to your advantage. Even if a previous job was short term or didn’t seem significant to you, you gained experience there. Let the employers know about everything you can do. Another thing you must do as a freelancer is to be very consistent and organized. An employer will be much more likely to rehire you if you turn out a good product. Everything you turn in should be clear and professional. Always meet deadlines. While most of the freelance jobs are extremely flexible, allowing you to work at your convenience, there are still deadlines. The work needs to be finished when the employer asks for it. Most of the qualities that will get you more freelance jobs only require common sense and a good work ethic. Living on Sparse Paychecks One downside of freelance jobs is that they are not necessarily consistent. Especially if you jump from one job to another, working for different companies, you will not have any guarantee about how much you will get paid each month. The flexibility may or may not be worth the uncertainty of freelancing to you. If you can manage to save effectively, the distance between paychecks won’t matter. If you do get frustrated about always wondering where the next paycheck is coming from, just remind yourself that the trade off is getting to enjoy more precious time not tied to a desk. There are definitely pros and cons when it comes to freelancing. You just need to decide how important it is to you to prioritize your life around what really matters to you.

What Career Coaching Can Do to Help Land a Better Job A career coach is something many people have heard of but few actually understand what they do.

In addition, a career coach can help you make sure that when you go into a job interview you can present yourself as on top of the latest developments in the field and as a person who could jump right into the job without needing a lot of training or guidance. The same goes for someone who is trying to get a job in a new field. A career coach will give you pointers about that field and the companies in the field as well as giving you general advice about the typical culture of that business – what kind of lingo is used, where the industry is centered, who the big players are, and even how to dress for your interview so that you look the part. Career coaches can also make sure your resume is in order and showing off your skills in the best light possible. This help a career coach provides when you know what kind of job you are looking for is all well and good, but they can do even more when you know you need a job, but you just don’t know what you want to do.

Do you have a problem with your interpersonal working relationships, or are you bad at delegating so you always end up doing all of the work? A career coach will work with your to set these problems right. When you need a better job, a career coach can clear the path for job improvement.
