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: 188.8.131.52
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.
Find a copyright lawyer How to find copyright lawyer Finding a copyright lawyer isn?t as hard as it use to be, not as long as you actually know how to find a copyright lawyer. Today, there are more copyright lawyers popping up than there were 10 years ago. It seems that having a copyright or needing to protect one has become very popular with the way our technology is advancing. One way to find a copyright lawyer is to simply type the phrase, ?copyright lawyer? into a search engine and click on a few links. Many pages will actually allow you to choose the state in which you live to find one nearby. You?ll may even be given a choice of cities to choose from and if you are lucky enough one will be the actual town you live in. If not that is fine too, most copyright lawyers will have a phone number or an email address for you to contact them. Chances are they may even be willing to work with you online instead of you having to drive down and meet with them. Copyright lawyers know the world is changing and that most people searching for them want someone that actually practices what they preach. They want someone that knows the internet and is up-to-date with the times, not someone that has a degree in the field but only does it as a hobby. You want them because they?ve done several cases and know what they are doing and will have the time to do it. Which is probably why many people are able to find copyright lawyer homepages or their own websites, which means getting to know the lawyer before they even call them. Search the lawyers name and find out all there is to know about them before you hire him/her. You don?t want someone that has a lot of complaints about; you want the person that has high praises. When you are trying to find a copyright lawyer keep in mind exactly what it is you need them for. There are certain types of copyright lawyers they deal with different areas such as lyrics, stories, website designs and many other forms. For instance if you have just found out that someone has copied an article or a blog you have out there in cyberspace you may want to find a copyright lawyer that deals with copyright infringement, maybe a intellectual property lawyer. If you aren?t sure if you have stuff out there that is being copied you may want to check over at copyscape.com. Before you find a copyright lawyer you should make sure you have all your information in order. If you are insisting someone else is using your stuff, make sure you have proof. One good way to do this is by marking the date you wrote it and then sealing it in an envelope and mailing it to yourself. Making sure to never open the sealed envelope. Make sure any work you do online is saved to a disk so you?ll always have proof. Your lawyer should be able to tell you everything you need before meeting with him/her. Finding a lawyer wasn?t hard and you even learned how to find out if he/she is any good by browsing the internet. Don?t just take them at their word, find out for sure. Or if you are lucky enough, you may know someone that has already used one and can recommend a good one for you. Now that you know how to find a copyright lawyer, you just need to make sure you can afford him/her.
To-Do Lists an Important Part of Being a Better Employee What makes a good employee? Take a look at how the star employee in your office operates. Chances are that they don?t run around in a constant fog of stress and pressure. Good employees are usually calm and conscientious; they seem to always get the job done with a minimum of hair pulling and frantic rushing around. Is it just genes that these people have that allow them to work like this, or are some people just better at managing stress than others? The answer is probably not. If you take a closer look at the star employee in your office, you will are likely to see that they are so stress free and productive because they are good at managing their time. And chances are they manage that time with the help of a to-do list. The to-do list is an often-overlooked part of working life. While they are the kind of thing people expect housewives to carry around with them in their purse while they run errands, many people think they can do without them in the work place. This is a big mistake. Being productive at work is all about being able to carry out your tasks in a timely manner, and being productive at work is also about managing your stress. If you are too stressed out, your work will suffer for it. You will fall behind because you won?t be able to concentrate, and you will make mistakes you might not have made if you were able to take your time with your work. So, how can a to-do list help? To-do lists can do many things for you in your busy working life. For starters, to-do lists remove the problem of having that all important phone call or meetings slip your mind. When you have a to-do list, everything that needs to be accomplished is set out there for you, so there is no more explaining to your boss why you stood up your company?s most important client. With a to-do list, you can also see the bigger picture of everything that needs to be done, so you can plan your time wisely. Working on tasks one after another as they come up is not a smart way to accomplish things at the office. Some jobs are on a tight deadline, while other jobs can stand to wait a little while. When you set everything out for yourself in a to-do list, you will be able to prioritize your tasks in order of importance, so you get the crucial work out of the way first thing, and only move on to less important jobs when you have the time to devote to them. All of this organization will make your working life less stressful. Imagine a typical day without a to-do list. You come in to the office in the morning, you work through all of the email sitting in your inbox, you make a few phone calls, chat with some co-workers in the break room, answer a few more emails, and then bam! All of the sudden, you remember that the presentation your boss needs for the big meeting is due at 2 p.m., and you haven?t even started it. Now you resort to hair pulling and frantic working. Then, you give your boss the presentation over an hour late, and it is filled with mistakes and sloppy work. Now imagine the same day with a to-do list. You get the presentation out of the way first thing, and you have time to check it. Then you can move on to less important tasks without the dark cloud of stress hanging over you. To-do list writing is time well spent if you want to succeed at work.
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.
