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.

Bring These Important Tips to the Table in a Telecommuting Argument Are you tired of the sound of the alarm clock every morning? Are you equally tired of trying to figure out what to wear every day (ladies) and fighting the rush hour traffic to get to the office in time? How about spending almost your entire paycheck on gas to put in your car to get you to work? There is a way around all of this of course – telecommuting. When you telecommute to work, you can catch a little bit of extra shut eye and head to work in your pajamas, without even getting in the shower. But aside from the convenience factor, there can be a lot of other good reasons why telecommuting makes sense. If you can put together a convincing enough argument for your employer, you may find yourself going to work in your bedroom slippers before you know it. The first thing you have to keep in mind about your telecommuting argument is that you have to make sure you have plenty of evidence that telecommuting will be beneficial to your employer, not just you. Sure, you would love to be able to see the kids off to school in the morning and take your coffee break in front of your favorite soap operas, but your boss doesn’t care about all of that. Though you don’t have to hide the fact that telecommuting will obviously have its privileges for you from your boss, remember to include plenty of ammunition for benefits to the company as well. What can you bring to the table in terms of telecommuting advantages for your boss? Point your boss to a growing amount of research on the internet that shows that big companies have seen big increases in productivity when they started letting people telecommute and work from the comfort of their homes. Everyone knows that a rested and stress free employee is a productive one, and offices can be filled with more distractions than your home (gossiping employees, phones always ringing). Some companies have seen increases in productivity of over 50%, something that is sure to get your boss’s attention. You can also point out to your boss that absenteeism takes a nosedive when people telecommute. No need to take a fake sick day to get out of going to office when you work from home, and even when people are under the weather, when the office is in the next room, they still tend to get a few things done on a day that would have been a total write off otherwise. Another selling point for your boss may be that everyone else is already doing it. More than half of the companies in the US have employees that telecommute, with great results. Your boss won’t want to let the company fall behind – and your boss will know that offering what other companies have is important for employee retention. Make sure your boss knows that what you are asking for is not out of the ordinary in any way. Beyond the selling points for your boss, you can be specific about a few benefits to you. Bosses know that gas is major issue for employees – telecommuting is a way they can let you cut back on that big expense, without feeling under pressure to respond with wage hikes. If you have customers that live near your house, let your boss know it will be easier to meet them face-to-face if you work from home. Last but not least, let your boss know that you believe you can deliver more to the company from the comfort of your home - more work for the same pay is always music to an employer’s ears.

Continuing Education Key to Being a Better Employee Employers now recognize the importance of continuing education for employees. Over the past few years, more and more employers have begun to offer tuition reimbursement and continuing education classes to their employees. While this was once thought of as an excessive expensive, it is now understood that continuing education benefits the company as much or more as it does the employee. The job market is becoming more and more competitive everyday. Only the best employees are getting jobs in certain sectors. That means that your skills need to be sharp in order for you to remain valuable to your company. This is where continuing education comes into play. No matter what type of job you have, just about all companies are investing in continuing education. The reasons why are simple. Even though the company may spend a good deal of money on continuing education for their employees, they see an even larger return. By having employees that are on the top of their game, the company will be more productive as a whole. Thus the company will make more money. With that in mind, it is very important that employees always take advantage of continuing education classes when they can. You will be able to stay on top of whatever new trends are coming up and possibly acquire skills that will allow you to move up in the company. By taking continuing education classes, you will become more productive. Studies have found that employees that continue to have their skills refreshed and renewed are more productive on the job. This is a perk for both employees and their employers. You will be able to finish more work in less time and with more understanding. Thus making your time at work easier. If you are not sold on the idea of continuing education, think of it this way. Your employer is paying for it. It is a perk of your job that you should take full advantage of. If you are working towards acquiring skills that will lead you to a promotion or an entirely new job, you are doing something to better yourself. And, it is costing you less, or nothing at all. The best companies to work for in the country have great training programs. This is no coincidence. These companies, which also make a ton of money spend thousands of dollars training their employees so that they can go out and make the company the most money possible. Less successful companies have begun to follow suit. No matter what type of job you have, there are continuing education programs that can help enhance your job experience. Continuing education is a great way to break out of a rut. If you are eager to change jobs or get a promotion, you will fair much better in the job market if you do some continuing education. Use whatever means your company offers to better yourself and become more marketable. The type of continuing education you choose depends on your career goals. It is always helpful to have an advanced degree in a certain field. If tuition reimbursement for graduate school is an option, take it. Having a Master’s or PHD will help you become an expert in your field of study. If your job has company continuing education, take them up on it., Even if a promotion is not exactly what you are looking for, being cross trained is always a good idea. Gain as much in the way of knowledge and skills as you can. When you move on to your next job those skills will look great on your resume.
