All About The DNS Domain Name System
We all know that in the world of domain names today, the presence of the DNS domain name system is very much significant. It is interesting to know that the acronym DNS actually stands for Domain Name System/Service/Server. However, I will be using the term DNS domain name system here to provide you with a clear knowledge about the meaning of this particular thing.
The DNS domain name system is actually a powerful tool that contributes a great part in the domain name process. It is often described as an internet service that translates or transforms the domain names into an IP or Internet Protocol address.
Aside from knowing such basic function of the DNS domain name system, it is also interesting to learn that a basic possession of the DNS domain name system is caching. This property takes place in situations when a server welcomes information about a mapping, it caches that information. Therefore, with such function, a later question for similar mapping can use the cached output, and will not result to additional questions to other servers. And generally, the DNS domain name system applies the caching to optimize the cost of the search. But how does the DNS domain name system caching works?
In terms of caching, it is very nice to know that every server has a cache for currently applied names along with records of where the mapping data for a particular name was taken. So when a particular client is asking the server to determine a certain domain name, the DNS domain name system then does check if it has the power for a domain name, and if it does, the system doesn't need to cache the information. However, if it has no authority for a domain name, the DNS domain name system then checks its cache whether the domain name has been resolved currently, and if yes, the DNS domain name system reports the caching data to its clients.
There are some instances that the DNS domain name system cache can be examined when the system cached the data once, but didn't adjust it. Due to the reason that the information about a certain domain name can be changed, the server may have inaccurate data in its caching table. There is a certain value known as the Time to Live or known as TTL which is applied when to age the information. So whenever an authority responds to a request for a domain name, it then involves a Time to Live value in the answer which indicates how long it assures the binding to linger.
Putting the Magic Back Into Young Adult Fantasy
As the market becomes saturated with young adult fantasy books in the "Harry Potter" mold, how long will it be before the genre loses its magic?
"If, like me, you've noticed that the spell being cast by the latest crop of young adult fantasy novels is becoming less potent, it seems a fair question to ask," said R.J. Nimmo, a young adult novelist and expert on entertainment for children.
Nimmo doesn't dispute the continued popularity of the sword-and-sorcery retreads out there.
"Nonetheless, assorted witches, djinn and goblins risk succumbing to that well-known pitfall of every successful celebrity from boy bands to Britney: overexposure," he said.
Nimmo says the genre's rise in popularity was initially due to J.K. Rowling's wildly successful "Harry Potter" series and was further compounded by the success of the "Dark Materials" trilogy by Philip Pullman.
"They are all fantastic books - genuinely fun and original," Nimmo said. "The problem is the market is becoming saturated. One more insipid 'Harry Potter' clone may be one too many."
So how can parents find worthwhile reading choices that their kids - whose appetites for fantasy fiction show no sign of abating - will want to open and read?
"The trick is to find books for children and young adults where the fantasy genre elements are infused as part of historical-inspired stories, thus sharpening the emotional, intellectual and educational edge," Nimmo said.
"The Ancient Egyptian Ennead," Nimmo's latest myth-inspired novel set in Egypt in the time of the pharaohs, promises to do just that.
"The magic in my books is something readers can identify with: the magic of learning about ancient civilizations, gods, myths and monsters," he said. "It's the way forward for an increasingly lackluster genre. I want to put the magic back in the hands of the reader."
