The "Catch" to Some of these Freebie Sites Remember that old saying, "There's no such thing as a free lunch?" Well, it's not true—there are plenty of freebies out there. However, there are some things you should know about if you are going to go after these freebies. The World Wide Web is awash with web sites that like to offer visitors with loads of tempting freebies. But although many of these are legitimate offers, there are some things you should know about these freebie sites. Here are some things to know about these freebie sites. Getting Things for Free—A Caveat Here is the basic caveat when it comes to these freebie offers—there is usually something you will have to endure in order to get your freebie. Although you may not have to make any sort of financial contribution or monetary expense, you will have to pay in some small non-monetary way. Here is a quick rundown of various kinds of 'catches' that you may come across as you seek out the best of the web's freebies. Watching Ads Before You Get to the Good Stuff One of the most common techniques that websites will use before you can get access to their freebies is to force you to watch ads. There are many different versions of this method. Many sites that promote freebies will support their site through advertisements. Most advertisements show up as pop-up or banner ads. Some websites also use video websites. With the ubiquity of high speed Internet, video ads have lately become the preferred method of advertisement on many websites. The less subtle of these ads are the pop-up and banner ads. Pop-up ads are often quite obtrusive and they can interrupt your enjoyment of the website. You might want to avoid ad-based freebie sites at work, as these can often interfere with your screen. Many popular freebie websites also offer ad-free versions of their content. This may be something to consider if you really find the website's content valuable. Be Wary of Automatic E-mail Sign-Ups Many freebie websites will sign you up automatically for their email newsletters. The worst-case scenario is when the website allows its partners to bombard you with email ads. What is the best way to avoid getting on an unwanted email list? Read the fine print, and whenever you get the option, uncheck the opt-in box at the very bottom of the page. Take Care of Your Privacy Many sites that offer freebies make money by selling the personal information that they gain from their web traffic. In order to avoid having your personal information being sold, you should avoid giving your personal information to websites that can't provide you with an upfront privacy policy. You should also look for the TRUSTe seal that ensures your personal information is kept secure and private. Also, never provide more information than you need to provide. Avoid Large Downloads Whenever Possible Another thing you should watch out for are large downloads. Although there are many legitimate large downloads out there, you should avoid sites that don't tell you exactly what you are downloading, how long the download will take, and how big the file size is. Watch Out for Disappearing Websites If there is one thing to know about freebie websites is that they are often 'here today, gone tomorrow' type enterprises. Many freebie websites simply don't survive for very long. You should think hard before committing to a website that offers free services that you will have to depend on. The last thing you want is to depend on a website's services, and then have those services disappear or suspended.

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.
