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.

Four Ways to Be a Great Employee Many people in the workforce and go to a job every day face similar problems. These problems include problems such as being a good employee, getting that raise at the end of evaluation period, keeping the job and many more. There are many things that you can do to ensure that you do not get fired or you get the raise that you deserve. Perhaps you just want to learn how to become a model employee. This article will discuss four ways to be a great employee. To be a great employee, your boss first of all wants to see results and good work. If you love your job, giving results, turning projects in on time, mastering difficult assignments is most likely a breeze. But if you are working to make a living and this job is not your dream job, you still need to deliver good work. Often times to be able to deliver your work on time and meet deadlines, it is important to be very organized and efficient. Many employees lack the efficiency needed to do their job right. If your job is a desk job, it might help if you just go ahead and clean up your desk, organize information and get a clear idea of which materials are stored where. A messy desk will leave you searching for the information needed to fulfill your assignment. This takes valuable time out of your schedule, time lost you cannot afford to loose. Another very important way to be a great employee is to be on time and not leave early. Employers like to see their employees arrive at time or just a little bit early, so they know that their employees are ready to start a good days of work when they finally put away their coat and get their coffee. Many of people come in and easily take 15 minutes before really are getting started with work. Employers see this time as a down time of yours and showing your employer that you do care about your work by showing up on time and if needed staying longer, is very much appreciated. If you are almost finished with your assignment, but it is time to go, do not get up, put your jacket on and wait the few minutes left for clocking out. Finish your work then finish your customer call or whatever necessary and then you can leave work. Sleep. Yes, sleep means going to bed early enough to get the necessary rest for your body. A well-rested mind and body makes a great difference. If you are lacking sleep or you are tired at work, you are more likely to make mistakes and forget things. Work is not the place to relax and sleep, but so many of the employees come tired. In some jobs mistakes can be fatal or ruin products worth hundreds and thousands dollars to the company. Another good reason to be rested well is that work will flow easier. You are a nicer person and your happy attitude at work will be recognized by others and is sometimes infectious and can help motivate others. Number four on the list to being a great employee is dressing appropriately. Whether your office has a dress code or not, if you work in an office, wear office appropriate clothing out of respect to your boss, colleagues and customers. Many offices have established dress codes because their employees come with the ripped jeans or dirty shorts while customers could potentially show up at any minute. Nothing makes a worse first impression on a customer than the cloths you wear.
