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.

To-Do Lists an Important Part of Being a Better Employee What makes a good employee? Take a look at how the star employee in your office operates. Chances are that they don?t run around in a constant fog of stress and pressure. Good employees are usually calm and conscientious; they seem to always get the job done with a minimum of hair pulling and frantic rushing around. Is it just genes that these people have that allow them to work like this, or are some people just better at managing stress than others? The answer is probably not. If you take a closer look at the star employee in your office, you will are likely to see that they are so stress free and productive because they are good at managing their time. And chances are they manage that time with the help of a to-do list. The to-do list is an often-overlooked part of working life. While they are the kind of thing people expect housewives to carry around with them in their purse while they run errands, many people think they can do without them in the work place. This is a big mistake. Being productive at work is all about being able to carry out your tasks in a timely manner, and being productive at work is also about managing your stress. If you are too stressed out, your work will suffer for it. You will fall behind because you won?t be able to concentrate, and you will make mistakes you might not have made if you were able to take your time with your work. So, how can a to-do list help? To-do lists can do many things for you in your busy working life. For starters, to-do lists remove the problem of having that all important phone call or meetings slip your mind. When you have a to-do list, everything that needs to be accomplished is set out there for you, so there is no more explaining to your boss why you stood up your company?s most important client. With a to-do list, you can also see the bigger picture of everything that needs to be done, so you can plan your time wisely. Working on tasks one after another as they come up is not a smart way to accomplish things at the office. Some jobs are on a tight deadline, while other jobs can stand to wait a little while. When you set everything out for yourself in a to-do list, you will be able to prioritize your tasks in order of importance, so you get the crucial work out of the way first thing, and only move on to less important jobs when you have the time to devote to them. All of this organization will make your working life less stressful. Imagine a typical day without a to-do list. You come in to the office in the morning, you work through all of the email sitting in your inbox, you make a few phone calls, chat with some co-workers in the break room, answer a few more emails, and then bam! All of the sudden, you remember that the presentation your boss needs for the big meeting is due at 2 p.m., and you haven?t even started it. Now you resort to hair pulling and frantic working. Then, you give your boss the presentation over an hour late, and it is filled with mistakes and sloppy work. Now imagine the same day with a to-do list. You get the presentation out of the way first thing, and you have time to check it. Then you can move on to less important tasks without the dark cloud of stress hanging over you. To-do list writing is time well spent if you want to succeed at work.
