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.
Software copyright act The Software Copyright Act was a Great Step in the Right Direction The software copyright act, which is actually called the Digital Millennium Copyright Act has given software developers a little more power when it comes to protecting their works. If you've bought software in the last few years I'm sure you've noticed some of the changes that have been made in the software buying process. If not, then you really should wake up and take note. Some of the more noteworthy achievements of this act are the following: 1) It is now a crime to go around anti-piracy measures in software. 2) It is no longer legal to make, sale, or give away software or devices that were invented for the purpose of cracking codes enabling the illegal copying of software. 3) Limits the liability that ISPs (as far as copyright infringement violations) when information is transmitted online. The problem isn't the people want to be bad or do something wrong. Most of us by nature want to do the right thing. The problem lies in educating people to the fact that it really is stealing when you bootleg, pirate, illegally download, or otherwise acquire copies of software that you didn't pay for. It's one of those 'white lie' types of crimes for most people and they don't really see how it will hurt anyone for them to copy a game that their brother, cousin, uncle, or friend has. Someone paid for it after all. The problem is that at $50 plus being the average price for computer games and simple software if 10 million people are doing it, the numbers are staggering and they add up quickly. The software copyright act sought to protect businesses from losing money this way. The software copyright act was the worldwide response to a growing problem. This problem was so widespread with illegal downloading of music that lawsuits and massive commercial ad campaigns were initiated in order to curtail illegal downloading activities when it comes to music. It seems to be working to some degree. Fewer people are illegally downloading music; the downside is that these people aren't buying as much music either. The reason is because they are no longer being exposed to the wide variety of music and artists that they were getting freely when downloading music each night at no cost. This equals lower record sales and is becoming a problem of lower movie sales and software sales as well. People aren't trying new games like they could before the software copyright act by going to LAN parties and everyone sharing a copy to play, now everyone has to own a copy before they can play. While this may be great for the companies that make a few (a minimal few at best) extra sales on the games for the sake of a great party but for the most part, it is costing them the extra money that could be made by 10 people finding they liked the game enough to go out and buy it so they could play it whenever (and the next group of 10 they will introduce the game to) Gamers are a funny group and software copyright act or no, they are going to stick with the software and games that serve them best. The software copyright act was created in order to protect the rights of those writing and developing computer software. We want those who fill our lives with fun games, useful tools, and great ways to connect to friends and family to continue providing these great services and to get paid for the ones they've already provided. The software copyright act is one giant step in the right direction as far as I'm concerned. Some Info on Those “Get Paid To” Sites Where You Can Get Free Stuff Anyone who has spent even five minutes online is aware that there are many websites that offer free stuff, and many people cash in on hundreds of dollars of free stuff every single month. But what about taking that one step further? What if you could not only get some free stuff, but also actually get paid to get free things? It sounds impossible but actually you can make a profit on getting free things online. The catch is that you have to devote a little bit of time and effort to finding these deals and completing them, but many people find that getting paid to get free things is well worth a little time investment. One of the top places to cash in for free stuff is so called “get paid to” websites. These “get paid to” websites usually act as clearinghouses for all kinds of internet offers that give users the chance to make some quick cash by completing some tasks. Most of the time, the tasks you have to complete on these “get paid to” websites involve filling out some kind of survey or submitting your contact information to a company. When you visit one of these websites, you can often click through offer after offer and complete them in your own time, racking up the cash along the way. But sure, filling out surveys is a way to get paid for doing something very easy, but what about getting paid to get free stuff? These offers also appear on these websites. Most often, you will get a free meal at a local restaurant and then get paid for submitting a report about your experience there. This kind of “mystery shopper” deal is also in place at many big chain stores, where you may be given a gift card for a small amount to go into the store, buy something and report back about your experience. Companies use these services to test their customer service in stores and figure out what they could be doing better. So, not only will you get a free meal or a free item at a store, you’ll get paid for telling the company if you were treated well by the staff – not a bad gig if you can get it! The way to get one of the deals is to keep a close eye on the “get paid to” websites. There are many of these websites out there, so the best way to figure out which ones are worth your time is to look for ones that have deals on offer from big name companies that you know. Most of the times, a major company will work with one website exclusively, so you getting in with the website that has the biggest number of big name companies mean you will have access to the most valuable “get paid to” deals on offer. Is there a catch to all of this free stuff? Well, there can be, but you can mitigate the hassle to some extent. The biggest problem with free stuff online is that you have to hand over your email address to a company who is sure to both solicit you in the future and sell your email address to other companies who will also start soliciting you by email. Cut the hassle by setting up a separate email address just for these purposes, so that your primary email address does not struggle under the weight of the spam. Also, never give out your phone number – you can use a phony one with a 555 exchange or set up an online number that you use only for freebies. Managed properly, you can really get paid to get free stuff with a minimum amount of hassle. |
