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.
Yes, There Really is a Freebie Santa Claus If you are a cynic when it comes to offers of free stuff, you are not alone. Everyone has had notions like “there is no such thing as a free lunch” and “if it sounds too good to be true then it probably is” drilled into their heads, and for good reason – these things often hold water. On the flip side, there ARE actually lots of places you can score some decent free stuff, if you know where to look and are willing to devote some time to hunting them down. The key to getting the best free stuff with the least amount of hassle is to stick with that healthy cynicism but to also dipping your toe in the freebie pool little by little. But why would anyone give stuff away for free? It is certainly an obvious question, but if you stop to consider it for a moment, you can see that companies actually have a lot of motivation to give away free stuff. After all, if they give you something for free, you are bound to have a little soft spot for their company, and when you are ready to part with some cash, their product may near the top of your list. Also, by giving away free things, companies can convince people to try new products. You might not want to try a new kind of shampoo if you have to pay for it, but you’d certainly be willing to give a free sample a try. You may end up loving it and switching to that shampoo for good, turning you into a paying customer. Another reason a company might give you free stuff is to complete market research. This is where getting free things can get a little complicated for some people because the products may not cost you money, but the offer may cost you a little time. A company might ask you to take a survey of your buying habits before they give you a free offer, or they may ask you to provide feedback on a regular basis as you try their product for free. Some people balk at the time commitment required here, but for other people, filling out some paperwork is a small price to pay for some free stuff. Of course, to convert you into a customer or to communicate with you about market research, a company will have to contact you, which is complicated area number two for freebie lovers. You will almost always be forced to hand over your email address in order to cash in on a free offer, and that is a recipe for opening your inbox up to a barrage of spam (many companies sell your email address to offset the costs of their free promotions, which means the number of people soliciting you can go through the roof very quickly). If you want to avoid this downside of freebie hunting, set up a special email address specifically for your freebie deals. That way all of your spam goes to this one address and your regular email you use with family and friends remains free and clear. One final note of caution about free stuff online: a lot of scammers have hit on the idea of using pretend freebie offers to solicit personal information about people or to convince people to send them money. Don’t send money, even for postage, to a company you don’t know and never, ever give out personal information online. No reputable company is going to ask for your social security number or bank account details for a freebie offer, so don’t hand them out to anyone. When in doubt, skip it and move to the next freebie. The Convenience of Online Writing Degree Programs (online writing degree programs) Online writing degree programs are not readily available, but they are growing in popularity.

The online degree programs offer courses that teach students the basics of writing, including paragraph structure, theme writing, descriptive writing, tech writing, and grammar.

The beginner’s course teaches the basics of writing, but after taking them, students will be able to take more specific courses, such as creative writing and tech writing. The online programs give students more freedom, but the workload is almost the same and students will have more and more writing assignments as they move further into the degree program.
