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.
People caught of copyright infringement Why Are People Caught of Copyright Infringement? When you hear of people caught of copyright infringement, many different things can happen to them. First of all, copyright infringement is both a civil and criminal crime, so people caught of copyright infringement are likely to get both sued and tried in criminal court. Because of the nature of copyright laws, if and when people are caught of copyright infringement, it?s likely that they will get repercussions from far and wide. First of all, people are always looking for people violating copyright laws. Copyright owners and/or agents surf the internet, so they may find the violations themselves. Usually, is someone finds that people are violating their copyright rights, they?ll notify the person or entities involved and ask that they take the content down, if it?s available on the Internet. They do this by either asking the person directly to take it down, or demanding of the website server to take it down (which they will, immediately, and probably suspend the account) If the person or entity hosting the violation doesn?t take it down, more serious actions will be taken, such as a lawsuit or criminal charge. People caught for copyright infringement do not automatically go to jail, although some entities like major television, music, and movie publishers and distribution channels may lead you to believe otherwise. For the example of YouTube.com, there are many people caught for copyright infringement, but they only need to take down the material. In many cases, YouTube.com will take the material down before the poster (the person who put the copyrighted information on the site to begin with) has a chance to see the warning. Other times, a work will be present on a peer to peer file sharing service, such as Kazaa or Napster, and the host of said service will blame the end user (you!). So, even if you found a file on a file sharing service, such as Kazaa, doesn?t mean the copyright is open for you to take it. Many people caught of copyright infringement have been found through these peer to peer networks, and it has been found time and again that the user that downloads the material gets charged and not the file sharing service. Be careful, if you are ever to use a peer to peer service such as Kazaa (or bit torrent, which is the code/program for another type of peer to peer file distribution tool) that you?re only downloading, and sharing, items that aren?t copyrighted works ? or you could be punished severely. Sometimes, people are caught of file sharing from their IP addresses ? because they download something from a secure site, their servers can track your IP address (your unique location on the internet, four sets of numbers, separated by periods, with at most three numbers in each set ? i.e. 216.239.51.100 which is the IP address of Google.com). So even if you think you?ve bypassed the copyright law, you can still be found years later by tracing that IP address. There are many ways to find people caught of copyright infringement, you can search through Google.com or look through newspaper databases. One thing, however, remains the same in all these cases ? the people are downloading, sharing, or in some other way using copyrighted materials. The only problem is, especially in the internet age, is that even if you?re using something anonymously, you can still be tracked ? and prosecuted ? for the infringement. Be careful, in all you download or use, have the rights to use the item ? sometimes it?s as simple as asking permission that will keep you from getting sued or sent to jail. Judging by Appearance ? It Happens in the Workplace This is one of the old sayings that really does come true, the clothes do make a person. What does it mean? For many people, it means that people judge by the clothes you wear. This is especially true in the workplace, but also for everyday life. Many companies nowadays have a dress policy in place to keep the appearances at work up. Reasons why companies have dress policies are of a great variety. Here is a review. One of the biggest reasons for companies to require nice appropriate clothing at least in their office area is visiting customers. If your employees need to be in contact with customers on daily or weekly bases or if customers do visit your offices in general, it is important that your employees make a good first impression. First impressions are very much guided by what you are wearing, your facial impressions and body posture. Therefore, if your customer see your employees working on their desks, it is important that the employees are dressed appropriately. For most workplaces this means a button down or polo shirt, dress pants or casual dress pants. In some instances, it is important for the employees to wear a tie and suit. For women, the codes are equivalent what the style of the clothing is referring to. Imagine what would happen if a customer comes into a company and the employee receiving the customer wears dirty, spotty, old and ripped clothes. In society that does not make a good impression, then the customer will most likely not want to do business with you. Another reason of why companies and employers would judge by your appearance is called professionalism. In the picture of professionalism at the workplace includes good appropriate clothing. It belongs to being a good employee as much as doing your job right and being polite and respectful to your boss and colleagues at your workplace. In society much is judged by the way you dress. If you have ever walked into one of the better department stores with a set of old, worn clothes, what kind of response do you get from the sales person? Often times they think you do not have enough money to buy here anyways and that is the way they treat you. They may not even give you the time of day, even if you have a lot of money. They judge you by what you have on and this is certainly the case in the workplace as well. If you want to project a good image, then take a good look at what you wear before you step out of your door in the morning. There are many places where a dress code is required or expected, such as the church, the opera, the theater, better restaurants and many other places. The workplace is just one of many and whether you like it or not, appropriate clothing is what can make or keep you get the job. Many Internet sites, books and people that offer advice on interviews and getting that job, will emphasize the importance of nice appropriate clothing and the impact it can have when you wear something that stands out from the crowd. Most people have been raised to think that proper dress attire is what you should wear at work, but for some it still is more a mystery to them than anything else. |
