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 Smarter – Planting Seeds to Earn Employee of the Year To be awarded with the employee of the year and maybe even having your own plaque posted on the wall is the highest of rewards for some employees. With all the competition in the workplace, becoming the employee of the year is not an easy task. One of the first steps to becoming employee of the year is to be a good worker. Being a good worker actually includes lots of different strategies. A good worker is always on time and never leaves early without permission. Of great benefit to you as well as to others is to make sure that you have a pleasant attitude and lots of motivation. The lack of motivation in a workplace can slow down productivity immensely and if your boss sees that you are one major motivator in your department, a small seed towards that plaque is already planted. A good worker is also very well organized and works in an efficient manner. Efficiency with high quality results is a great combination to add more seeds to sprout your career and reach your goal of being the employee of the year. In some companies there is an employee awarded every month. The employee of the month gets awarded for his outstanding work and contribution to the company over the course of the month. Sometimes to become the employee of the year, you need to get several or the most of the employee of the month awards. But since you are trying to be the employee of the year, you must already try to be the best employee every month. You should have a chance for one or more of the monthly awards. Becoming employee of the months is one important seed to harvest your crop, the employee of the year award. Often times, it also helps to have a good relationship to your boss. A relationship of mutual respect, somebody your boss can rely on, likes to exchange ideas and just plain small talk with, are all important. Become his ally and best worker, but do not over do it. Sometimes in the effort to become employee of the year, you try too hard to be somebody you are not in order to show off in front of everybody and forget that working in a businesslike or industrial setting also means teamwork. Try to be a leader and show respect for others at your workplace. If you are just trying to take away work and glory from others, you will soon be the person nobody wants to go to. To become the employee of the year, you need to be a resource for others, help with their daily problems and most of all, respect them and recognize their accomplishments. If you are working in the team, everybody needs to feel welcome and feel like he or she is contributing. As you can see, just doing the most work will not get you the employee of the year reward. Accomplishing many other things at the same time is just as important as the amount of work you correctly and timely deliver. That is why the process of getting awarded is more like planting seeds in the field and seeing them sprout. It is not just one action; it takes many different actions to become the employee of the year. Possibly one of the most important facts at the end of the year-- do not expect that it is you that gets the award. Be humble, think of others that did also tremendous amounts of work and tried to be motivated throughout the year. Do not be disappointed if it is not you. |
