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.
Examine the Interior of Publishing Companies (publishing companies) The publishing company can be seen as the backbone of the writing world. Written words seemingly would not have been able to be seen without publishing companies. The publishing company provides a great service to society by publishing and displaying the work of authors. The existence of publishers is obvious, but the interior of the publishing world and its companies is unknown by many people. Publishing is known as an apprenticeship industry, which means that most of the knowledge needed by a publishing professional will be learned with hands-on experience on the job. Generally, information that is learned in one department of a company is useful throughout the publishing house, which gives professionals the opportunity to move between departments. There are many levels to a publishing company and they all have different functions. The administrative level is the first level of any company, and has many responsibilities in the functioning publishing companies. The administrative department is responsible for managing daily operations for publishing executives and management. This responsibility involves interaction with all of the employees from all of the departments, as well as interaction with authors and agents. The administrative employees are required to manage the calendar, maintain organized files, screen/prioritize mail, draft correspondence, make travel arrangements and prepare itineraries, process expense reports, take minutes at meetings and prepare reports. A position as an administrative employee allows a person to have a high-level of understanding of a publishing company, while being visible to executives. Advertising is another division of publishing companies. Most publishing companies have in-house advertising agencies that purchase media space and create and design advertisements. In a publishing company, the advertising department works closely with the marketing directors, editors, and publishers of titles to create an advertising plan that will promote sales of an individual book. Every advertising plan requires research and negotiation to provide the best venues and the most cost-effective methods of advertisement. These employees also work closely with graphic designers, commercial sales representatives, printing presses, and internal staff to facilitate the run of advertisements. The editorial department of a publishing house is one of the most important departments. This department acquires, negotiates, develops, and edits book projects for publication. The daily activities of editorial employees include preparing acquisitions for transmittal to the production department, developing and maintaining relationships with authors, booksellers, and agents, performing general administrative duties, participating in editorial, design and marketing meetings, and reading and evaluating submissions by writing reader?s reports. The editorial department must work closely with all departments. Another division of publishing companies is the marketing department. The marketing department has the responsibility of creating, preparing, and establishing marketing strategies and policies for each title by coordinating the efforts of the publicity, promotion, advertising, online, and sales departments. The marketing department is responsible for preparing all sales presentation materials, audio recordings, fact sheet collation, and promotions, creating and producing additional account-specific presentation materials, researching and establishing relations with new markets, and planning and maintaining sales and marketing schedules. The publisher?s office is also an important department for many publishing companies. The publishers oversee the life cycle of a title from acquisition to production, and onto the sales force. Publishers are responsible for making executive decisions for all titles within assigned imprints while staying within any cost restraints. This department is also responsible for sponsoring book projects, strategies, and initiatives for the publishing company. The subsidiary rights and permissions department is also one of the most important divisions of a publishing company. This department finds additional sources of profit for a given title, including serials, book clubs, and paperback, audio and e-book rights. The daily activities for the subsidiary department include writing submission letters, sending manuscripts, proposals, and books to foreign publishers and agents, coordinating co-productions with other publishers, working with book clubs and sales for special editions, and maintaining relationships with other publishing companies. Publishing companies have many divisions, including, sales, purchasing, publicity, promotion, production, managing editorial, legal contracts Internet development, information technology, human resources, finance, art and design, and audio.
Why Taking that Vacation Can Lead to a Better Workplace Do you love your vacations? Are they relaxing, fun and entertaining? There are many reasons why a vacation can enrich your life and fulfill you with joy and happiness. But many of these reasons actually can also be directly translated into reasons for why taking that vacation can lead to a better workplace for you, your boss and other employees. Vacations are as essential to a hard working employee as a parachute to a person jumping from an airplane with the goal to land safely. Many employers would love to minimize the time you are gone from your workplace because they think the more time you spend there, the more work you will accomplish. This argument is right up to a certain amount of hours and days a months or a year, but whenever your body starts to get tired and exhausted, the amount of work that you produce decreases. The quality of your work starts to decline as well. Time off work, time together with your family, time to relax, time to regenerate and time to just plain have fun are very important in an employees life. Taking a vacation has many benefits to the employee, but also to the company you work for. The more relaxed and happy your worker starts a workday or the workweek; the better will most likely be his or her performances at work. Research has shown that relaxation and regeneration are essential to human bodies. Did you know that in some companies in Europe and Asia, the emphasis on relaxation goes so far that meditation, morning sport and a short power nap belong to their required parts of a work day? The United States is actually one of the only industrialized countries that does not mandate a minimum of vacation days that the worker has to take off. In fact, in many countries in Europe, a minimum of 20 and more days is the norm. Since the late 1970s, the average middle income family works in total hours three and more months a year more then they did back then and according to a research done by Boston College, approximately 25% of Americans do not take a vacation at all. After all these facts are slowly emerging from mounts of collected date, some of the bigger American companies have actually begun to realize that off-time and vacation are essential to prevent mishaps and screwed up designs and products. If you are not taking your vacation or your employers does not allow for any vacation, a series of health hazards such as stress and high stress, sleeplessness, burnout, heart attacks and even more serious health conditions can occur. Another big factor in working too much, working overtime or never having vacation can be problems and loss of family and friends. Problems with families and friends will directly impact performance at work and even though the employee might not talk about it at work or might b e holding back his or her feelings, the mood and general behavior of the employee will have an impact ion his work and other employees. Every employee should value the vacation time given to him or her and employers should grant the time asked for to their employees. Vacation is essential to the performance at work and the quality in products the company can deliver. Following the examples that are set by many European countries, the US should give their employees the time they need and also make sure that their employees do take the time off to be a better employee overall. Vacation is fun, relaxing and regenerating.
