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.
Get Noticed at your Job by Doing it with Flair Doing your job with ?37 pieces of flair? may have entered the pop culture vernacular through the famous movie about life working an office, Office Space, but there may just be something to it. You might not need 37 pieces of flair, but doing your job with a little bit of flair and a lot of hard work is a great way to get noticed in the office and to move on to bigger and better things. How do you go about doing your job with flair? The first way to make sure you are doing your job with distinction doesn?t involve much flair at all ? it simply involves doing your job and doing it well. Know exactly what your responsibilities are and attend to them every day. Don?t let any of the things that come under your job description fall by the wayside because you think they are unimportant. If you are unsure exactly what all of your responsibilities are, ask your boss for a meeting and discuss your job description with them. You will get noticed simply for your desire to make sure you are covering all of your bases and not letting any of your responsibilities fall by the wayside. Another way to do your job with flair is to add to the good morale in the office. Everyone has at least one person in the office that is like a black cloud hanging in the air. Gloom, doom and pessimism don?t really have a place in the office. Even if you feel like you are heading for a fall with the way a certain project is coming together or because someone on the team is not pulling their weight, look for solutions instead of standing around and complaining about it. When your attitude can help people stay on track with their work and not dread coming into the office every day, you are bound to get noticed. If you really want to add some flair to your work performance, learn how to manage your time and avoid procrastination. Time management is one of the biggest problems all employees face, and when you don?t manage your time efficiently, you are not being as productive as possible for your boss, which never wins you any fans among the management team. If you find yourself always rushing through your work at the last minute trying to meet your deadline, try keeping a journal of all of your activities at work for a few days. When you see how much time you spending doing things like talking with co-workers by the water cooler and surfing the net, you might see ways you can improve your work habits, so you can get things done well before the deadline is pressing down on you. Increasing your productivity by managing your time is a surefire way to earn some praise from the people over your head. Another way to add flair to your work performance is by being a team player. It can be tempting to thing that to have flair you have to go out on a limb and try to do everything yourself, but that is not the case. Employers don?t like to see an employee trying to hog credit for things that everyone has worked on together or trying to one up everyone else on the staff. When you work together with the team, you show your employer that your interests are with making the company a success and not trying to advance you own personal agenda. If your employer understands that you see the bigger picture of making the company succeed, you are sure to get noticed and rewarded. Freebie Etiquette (Yes, There is Such a Thing!) When you are on the hunt for free stuff, it can be easy to be so blinded by the offers that your manners go flying out the window completely. You may also just not realize that when it comes to taking advantage of freebies there is a general code of conduct that it pays to follow. While you are racking up the free stuff, keep these common courtesy rules in mind so that you are doing your part to keep the hunt for freebies fun and enjoyable. Freebie etiquette rule number one is to remember that there is a face behind every freebie, no matter how distant it may seem. Since so many freebies come from websites and you don?t actually have interaction with a human being while you are getting them, it can be very easy to forget that someone (or very likely, a lot of someones) worked hard to bring you that website and that free deal. If you have a problem with a website or a form while trying to get some free stuff, deal with it as respectfully as you would if you had to approach a customer service rep in person. Leaving foul-mouthed posts on a message board or unloading a barrage of outrage on a customer reply form isn?t the way forward. Someone ? a real person ? will have to help you, and you?ll get a lot further by treating them with respect. Respect is also the name of the game when it comes to rules attached for freebie offers. There are often restrictions in place for taking advantage of free offers, such as the age you have to be to cash in on the offer or how many offers per household can be taken. Sure, there are plenty of ways to get around these rules and ?trick? a company into giving you an offer for which you are not really eligible. However, when you try to simply bleed out as many free offers as you can, you?re only making it hard on companies to be able to keep bringing these offers to you. If this freebie isn?t for you, take a back seat and make room for the folks who can take advantage of it. Your time will come. Related to this last rule is the idea of not being too greedy when gobbling up the free stuff. Just because something is free doesn?t mean you should use a ?smash and grab? approach and go for as much as you can get of anything you can get. Remember that there are a lot of other people out there who like to get in on the freebies, too, and think about how you would feel if you lost out on something you really wanted because someone came along and took them all. Don?t take more than your share of any free offer, and don?t take things you don?t want or need just because they?re free. Everyone loses when you do that. Last but not least, if you have an opportunity to say thanks for a freebie, grab it. Of course, this can be hard to do when the free offers you are taking advantage of are found on the Internet, but there are still ways. Look for the customer comment field in the request forms you fill out to get your free stuff and leave a quick thank you there. You can also write a thank you on message boards and chat rooms that are associated with the freebie websites. The good will generated by your gratitude will only help convince companies that freebie offers are useful tools for reeling in the customers. |
