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.
Job Hunt Challenges for the Over 50 Crowd If you have just recently lost a job or maybe are not happy with the job you are currently holding, you are going to be on the hunt for a new job. Hunting for new job is never easy, whether it is your first or your tenth job. You know that it takes a good amount of preparation till you might hold another permanent job. But for the older crowd, especially the crowd over fifty, the challenge of finding a new job is even greater. Explore some of the facts why it is more challenging to find a job after 50. Starting out by the age factor, many companies want young and dynamic employees that are open to new and challenging tasks. Many employers believe that a person over 50 is set in his or her ways and therefore not able to tackle the same great tasks that might open up as a young, fresh out of college open minded person. A person over 50 is closer to retirement and might not want to take any risks as a young career fresh from school employee. Risks are sometimes what a company needs to get forward, new ideas, new thinking. Another reason is the salary competition. If you are over 50 and looking for another job, you most likely have a lot of experience in you sector. Experience usually is measured in money and the salary for an experienced person is generally higher than a starter salary. While experience is desired, some companies can just not afford to hire somebody for 10-20 thousand dollars more than they can get the fresh from college employee. If you lost your job, you might accept one of the lower salaries, but while you are in the application process, the human resource person reading your résumé does not have that information about you. Some of the bigger companies get scared by the fact that you are really close to retirement and if there are certain retirement plans and structure in place at a company, they might not want to hire you. You could retire within 10-15 years or less and then the company is stuck with paying you retirement payments. Hiring a younger person instead guarantees them no retirement payments or plans for retirement in general for the next 20-30 years. From the employer?s side, these are great savings for their pocket. Another reason often seen from employers as a reason not to hire a person over 50 is that the person they are hiring might be more prone to sickness and take more sick days than a young person. Why would they think that? Statistics have shown them that the tendency for time off due to sickness is greater for people crossing the age threshold of 50 years versus younger people. Be honest, being over 50 means for most people more aches and pains all over the body. You are more tired and get exhausted quicker. So if you do get a chance to go to an interview when looking for a new job, you need to make the best out of it. Besides all the factors mentioned above, a person that is over 50 and is looking for a job can be a great addition to any company and you need to make sure that you let your interviewer know that. An interview is a great challenge and can be mastered quite well if keeping these thoughts that employers have in mind. Emphasize the fact that you do bring experience and connections. Let them know that if they hire you, they get a person that at least is settled in life. You have had all your children, or did not want any, but at least you will not be missing because of pregnancy, birth of a child, and sickness of a young child or similar events.
Beautiful Pens are Just the Beginning: Fascinating Gifts for Writers (gifts for writers) Buying gifts is a difficult project in many cases. Sometimes a person seems to already have everything. They may not enjoy the typical gift ideas that come to your mind. To buy the perfect gift, it is essential to actually know a person. A basic understanding of likes and dislikes will help, but passions will guide you to a really great gift. If you cannot come to a conclusion for what to buy for a friend, you can also consult other sources for gift ideas. Following are some ideas for buying gifts for writers. Writers are passionate people. They are passionate about words and about truth. They are also passionate about their subject matter. Is there a writer in your life? By using these guidelines, along with your knowledge about that person, you can come up with an ideal gift that they will treasure. Under Twenty Dollars As suggested by the title, a beautiful pen is almost always an inexpensive and appropriate gift for a writer. Most writers spend much of their time jotting down thoughts and ideas. As they meander through their day, an idea may strike at any time. Give them a quality instrument to facilitate great thoughts. You can also include a personalized pad of paper to hold on to the brainstorms. Another great gift for a writer is a magazine subscription. A good writer needs to keep up with the type of writing that is being published. Sometimes they need a little bit of light reading to keep their creative juices flowing. Choose the magazine based on some interest that you and your friend share. Under One Hundred Dollars If you want to spend a little bit more on gifts for writers, you can start taking your gift buying to a little bit different level. For less than one hundred dollars your options open up. Books are great gifts for writers. You can buy new books in the writer?s area of interest or expertise. He will probably always be ready to expand his own knowledge base. You can also buy reference books. Style manuals are very helpful when a writer has strict guidelines to follow. Your writing friend probably already has a pretty good dictionary, but you can buy them the best one. Thesauruses and literary guides are also interesting gifts to receive. Moving away from words for a bit, a writer would also love to receive an artifact that has to do with their main subject matter. If he is a history buff, try to find an authentic coin from the particular piece of history he finds most fascinating. Under Five Hundred Dollars At the next level of gift buying, your options start expanding into more elaborate forms of previous gifts. Very old and rare books may fall into this price range. Very old or particularly good quality antiques will also be fairly expensive. Gifts for writers also often fall into the category of electronics. Good printers make the writing all that more impressive looking on the page. Software and other hardware for the computer is also a worthwhile gift for a writer that spends most of his day sitting at his computer. A nice digital camera is also a fantastic gift for a writer that wants to remember situations exactly in order to adequately describe them later. Won?t Cost you A Dime Some of the best gifts for writers won?t cost you anything. Many of the more expensive gifts are extremely practical, but the free ones can be that also. The nature of a writing career leads writers to spend a lot of time alone. A good gift is just some company. Take your friend out for dinner with a group of mutual friends. He?ll appreciate the time away from the desk. If he?s been trying to get an interview with someone, you can put the leg work in for him and schedule it. All that will cost you is some time and effort. Not all gifts have to cost money. Good luck finding the perfect one for the writer in your life.
Pertinent Advice for Negotiating Salary Your salary is a huge factor when it comes to job satisfaction and overall quality of life. That is why negotiating salary is something that you should never overlook. While many employers like to state that starting salary as if it were etched in stone, there is usually some leeway in how much you will make. Remember, what you make is going to affect your entire life. Negotiating your salary is something that you should take very seriously. There are a few things to consider before you start throwing out figures. You don?t want to lose the job you have just gotten. First of all, leave the salary negotiating for the end of the hiring process. This is important because if you agree to a lower salary earlier on in the hiring process, you will be locked into that salary. Also, as the hiring process goes on and you become more of an employee, opposed to an interview, your worth increases. If you have gone through several interviews and met a few different managers, you have been able to make an impression on a number of people. That means that several different people have measured your worth to the company. When salary negotiating comes around, you can ask for more money. With several different people discussing your salary there is a chance that your state price may win out. Before you begin negotiating salary, you should know how much you are worth. One of the most important aspects of job hunting is finding out how much your skills and talents are worth in the job market. Armed with this knowledge, you will be able to market yourself better and know whether or not the employer is bluffing you. If you know that the salary they are offering you is much less than other companies offering the same position are offering, start the negotiating. Employers are always looking for a bargain. They never shoot out the high end of salary numbers. Employers start out at the bottom of the salary barrel. That means you can work to boost the salary offer. Of course, you do not want to sabotage yourself by acting too cocky but do not crumble under pressure. Be savvy in your negotiating and recognize that if the company is hiring, they need you. Yes, you may need a job, but the need is mutual. They would not be going through the interview process if there were no need of your services. Also, they obviously were impressed with your credentials. Be sure that they appreciate you will a decent salary. Know when to start salary negotiation. When the employer is explaining the job description to you, if they state a salary that is lower than you would like, let that pass. Until you have been offered the position, you do not need to worry about the salary. The first thing is to get the job. Once the offer is made and you are filling out paper work, you can start the negotiating part of the deal. It is important to know when salary negotiating is not an option. There are certain jobs that offer a set salary for certain position. If you are interviewing for a job that has a stated, set salary, you do not want to negotiate. The stated salary is the one that you will be getting if you take the job. In these cases, whether or not you are willing to settle for less is the question at hand. If the salary is too low for you to handle, get out there and find an employer that appreciates your talents.
