Web Hosting - DNS, How The Internet Keeps Track of Names The way computers communicate is, in a way, very similar to something very familiar: the postal system that delivers letters and packages. Here's how... The Internet is just what the name suggests, a large inter-connected set of networks. But those networks are pointless without the one part that forms what is called their 'end-nodes', otherwise known as computers. Those computers often need to share information because the people who use them want to share information. But, in a system where there are millions of separate computers, how can you enable them all to communicate? One very important feature of that solution is performed by something called DNS, the Domain Name System. Every part of a network that is going to send or receive information is assigned an IP address. That's a numeric identifier that uniquely specifies a particular 'node', such as a computer, a router that directs traffic or other component. They look like this: 209.131.36.158 But those numbers are more difficult for people to remember and work with. They also aren't very attractive from a marketing perspective. So, a naming system was layered on top of some of them, mostly the computers involved, though routers have names, too. But once you have a system that associates a unique IP address to a given name, you need some way of keeping track of all of them. That's carried out by several different pieces of the system: Name Registrars, DNS Servers and other components. The Name Registrars, overseen by IANA (Internet Assigned Numbers Authority) and other international bodies, provide and keep track of domain names. When you register with GoDaddy or any of a hundred other intermediate companies, ultimately that information makes its way into a number of specialized databases stored inside DNS Servers. A DNS Server is the hardware and/or software that tracks and forwards the IP Address/Domain Name pair from one place to the next. In many cases, there are a number of them between your browser and the remote computer you want to share information with. Suppose you request information from, say, Yahoo's site by clicking on a link on their site. DNS resolves (translates) the name of WHO IS making the request and OF WHOM, to addresses, then passes the request through the network to the requested IP address. The requested data is then passed back through the mesh of network components to your computer and displayed in your browser. Whether the communication is between a desktop computer and a server somewhere, or between one server and another, the process is essentially the same. DNS servers translate names into IP addresses and the requests for data are forwarded on. In some cases those DNS servers are part of a specialized network computer whose sole job is to do the translation and forwarding. In other cases the DNS software may reside on a server that also houses a database of general data, or stores email, or performs other functions. But however complicated the chain or the parts, the basic process is simple. Translate the name to an address, just as the postal system does. Whether international or local, your name is associated with an address, and the deliveries are made to the address, then forwarded to a particular name.

The Top Virtually Bug-free Free Email Services on the Net Virtually bug-free e-mail services are available actually from several places. Many of these service providers are big names, known by many, especially Internet users. The difference between the different e-mail providers lies in several things. These differences include but are not limited to plenty storage space, effective spam filtering, a fast user-friendly interface, desktop e-mail program access and much more. Currently in the United States and the rest of the world, the best offer for free e-mail comes from Gmail. Gmail is part of the Google business enterprise (the search engine most of us know) and offers the most features and storage space for their users for free. With virtually unlimited storage capacity for e-mails, a user never has to delete any e-mails of the server and can collect all the messages. Gmail offers a simple user-friendly interface, which also includes an excellent search function that lets a user find messages instantly and precisely. Another great feature of gmail is the POP and IMAP access features. This gives the user the possibility to download the e-mail from the server with any e-mail program that the user generally would use. The program can then also automatically download the e-mails into the program ready for the user to read. Gmail is funded by displaying advertising next to the e-mails read. Next on the worldwide list would be GMX, a German provider that offers many of the features gmail offers, but with limited storage space. This program also has the POP feature and can therefore be used in conjunction with any of the common available PC e-mail programs. Right after gmail it is one of the most reliable e-mail services, but unfortunately they discontinued the English user face and only offer a German version now. Thereafter on the top free e-mail services providers is AIM Mail. It is the free web-based service from AOL. Like gmail it offers virtually unlimited online storage, excellent spam protection and a simple, easy to use interface. Unfortunately, AIM Mail lacks proper productivity, such things as labels, smart folders and message threading is not available. AIM Mail also offers a very functional POP and IMAP access. Yahoo! Mail would be the next e-mail service that should be mentioned on the list of the top virtually bug-free services on the Internet. Yahoo also offers virtually unlimited storage space for e-mails and a few other nice features, such as Short message services for texting to friends and family, instant-messaging features for the internet and up to date news feeds. What Yahoo! mail lacks is a really good spam filter. It offers a spam filter, but it is not effective enough. Also nice to have would be labeling options as well as smart folders. The Yahoo! Interface is just as easy and user-friendly as the other providers and fairly reliable. To complete the list we need to mention the following three services, Inbox.com, FastMail and Hotmail. Inbox.com offers e-mail users 5 GB of free space to store e-mail online. Despite the limited space, this service is outstanding due to its high-speed accessibility. Web access and POP access are very fast and even the search functions are faster than with most other services on the market. The drawbacks of Inbox.com are the missing IMAP access, only POP is provided and the organizing of mail is slightly unorganized due to missing smartfolder technology. FastMail on the other hand offers users only IMAP. It has many useful features and has one of the best web-based e-mail interfaces. It also generally displays fewer ads then the other services do. And lastly, Live Hotmail should be mentioned here, since most PC users that have a Windows based operating system will have heard of hotmail. This program offers 5 GB of storage for e-mails online. It has a fast search option, a solid security feature and the interface is as easy as the ones users are used to on their desktop. Even though security is great, the spam filter is not quite as effective as some of the other e-mail providers. Also missing with this provider is the POP and IMAP access as well as smartfolders and other great e-mail organizing features.

Get Roboform to Help with those Countless Online Forms for Free Stuff RoboForm, is a web site that offers users programs to make life on the Pc and on the Internet easier. These programs help the user to remember and securely store online and offline passwords. How often does it happen that someone forgets the PC password and then there is no other way than reinstalling the whole PC operating system? The programs offered by the website also help with many other Internet and PC issues and tasks. RoboForm can log the user automatically into online accounts, complete online registrations and complete checkout forms with just one click of the mouse. This makes the program a great help with the countless online forms that exist for free stuff. Over and over fill freebie seekers online forms. Name, address, e-mail, birth date and more and this program is able to fill the information into the online forms with essentially one mouse click. For example, for online sweepstakes entries, the most important factor to receiving free stuff is how often one is able to sign up for different sweepstakes. Hunting down online free stuff is already time consuming, but filling out all the long and tedious entry forms every single time takes even longer. The company states, that this program can help the consumer increase the number of filled forms for sweepstakes at least ten times, since the users identity is stored in the software and then used to fill the online forms. When sweepstakes allow for multiple entries, the program can speed up this process even more. The software offers the option to save the data into a file and then the user needs to just choose the data and hit the fill and submit button and the sweepstake entry is on its way. For consumers of the software it is important to know, that RoboForm will not disqualify consumers from the sweepstakes and as the company states is completely legal. The reason a user cannot be disqualified for using this program is that the company that offers the sweepstake will not even remotely know that a program was used. Data is saved on the user’s computer and just used to fill the forms. The filling happens just like when the consumer enters the information himself into the form. Even if programs state that automated entries are prohibited, this excludes this program. The automated entries are referring to programs that submit the data to the page without the user ever viewing the page. With this program the user is still required to open the page, view it, and then fill the forms. The only part done by the program is filling the form. The user then still has to check the filled form and hit the submit button on the page by himself. This is what makes the whole process legal and a good deal for freebie seekers. By many this software is called the best way to automat sweepstakes and increases the free stuff coming into the house. Due to the programs ability to save online addresses users can browse thru their sweepstake web pages without having to remember all the long URL addresses. Additionally due to the ability to save already filled forms, users can easily participate in daily sweepstakes for certain products. When combining this software with one of the online pages that offer links to free contests, free products and more, consumers can be showered in anything from free movie tickets, to food products and health products. Many consumers have positive feedbacks to offer about the amount of freebies they are able to get every month. Sometimes people apply for freebies, even if they do not really need them. There are always pages up there, where the product can be donated or sold to other people.
