What is the benefit and danger of children using tablet

Nowadays, the first import technology that has a deep impact on kids in the modern family is neither television nor desktop computer. A Nielsen survey of adults with children under the age of 12 in tablet-owning households states that 70% of those children use a tablet
(http://www.examiner.com/article/finally-a-tablet-market-for-children-ages-3-12). As we all know that, tablet computer is the popular digital technology now. Is it a good phenomenon?

Why do children usually love to use tablet? First of all, using tablet computer is more comfortable than desktop computer, even notebook computer. Tablet computer is a mini computer that has a large touch screen, which is the feature that smart phone cannot replace, even though it has similar function. Children can use the tablet everywhere easily, when compared to traditional computer, tablet computer can download apps to play or learn. Downloading apps is convenient, and there are lots of apps for entertainment or education.  
There are videos all around the internet that shows the broad range of apps for these purposes.
For example, this videochooses ten free apps for the children that is strongly recommend. Using the apps, children can learn ABC, the number, names of the animals and so on. Therefore, tablet can replace some books or educating tools that their parents buy for their children.
 

Also, if parents download the official Youtube apps, they can search for kids TV programs for their child and they can watch the TV programs any time. Other than education purposes, apps store (or Google play store) also have lots of various interesting game, such as FIFA 14 or candy crush. 
 

It can make children to forget their desktop computer. For the parents, tablets are usually cheaper than the PC or Notebook, which most of the family can afford and willing to buy for their children. Therefore, it is not a surprise from the research that many children are using these tablet computers..

 However, there are some dangers in using tablet that children must remind. A well financial control is the one of the remind of using tablet. In the apps store, some of the apps should be pay to download it. Moreover, some apps will require to pay the additional amount to open extra function. Parents should prevent their children to over-spending. (http://www.labnol.org/software/prevent-kids-from-buying-apps/), this article is talking about how to prevent kids to buy apps in app store, it may be an effective way to prevent overspending. Also, same as the traditional computer, if children spend many hours continuously in using tablet, they will likely suffer eye strain. On the other hand, Psychological, kids will addict on playing games in tablet. So not only the finance, parents also require to limit the using hours of their kids. Otherwise, it is the barrier of their growth, such as lack of the physical development.



In fact, no matter the children using what, parents should take care them carefully, it is the only way that help children growth properly.

Scam of the online auction

Online auction is one of the popular shopping method of people nowadays. It is the digital technology that hold an auction on a internet. Both buyers and seller can benefit with the online auction. For sellers, they can sell their merchandise with low cost, as they can reduce some fixed cost such as rent. For buyers, they have lots of opportunity can buy a cheap product in online auction. For example, they compete with other buyers in one dollar bid. Also, it is more convenient to shop any goods worldwide, such as using e-bay. There are lots of advantages in online auction, but whey many digital immigrants, even digital native keeps to shop in real world store? Auction scams may be the most obvious reason.

Although the auction website establish some of the strategy to defend, for instance, e-bay set up a ‘customer support’, to help e-bay user report their problem about the auction, and provide lots of guides for them, buyers cannot avoid all the scam in the online auction. Shill bidding is the typical auction fraud in the online auction. It is a strategy of seller that employ someone seek to provoke a bidding war among other participants, driving prices up with phony bids (http://en.wikipedia.org/wiki/Shill_bidding#Auctions). Buyers may pay a higher price to win the bid. In my opinion, shill bidding usually exist in ($1 bid), or selling vary product. (http://www.youtube.com/watch?v=71j6ZDx4j-g).  
There have some way to identify a Shill Bidder on eBay in this link, it can be as soon as possible to avoid shill bidding. However, shill bidder will not care their account of the auction website, they can create more and more account. For example, in e-bay, the account information is related to Paypal, but we cannot prevent they provide a faking information in applying Paypal. Therefore, buyers cannot defend the shill bidding happening eventually.

Not only the buyer, seller also will be facing a popular problem about online auction - the buyer giving up the bid, especially after bid close. In the digital world, many people forget their responsibility of their behavior, it is not surprise that buyers give up their bidding. In online auction website, seller should pay the publication fee for selling their merchandise. If the buyers give up the bid, they may lose their publication fee. Although some auction website may be refund the fee for seller, it is application and time wasting to get it. After the failure of communicating with the buyer about the bid, some of the sellers may give a 'bad' evaluation to these buyers, but I think it is a useless action. If the buyer give back you a bad feedback and 'bad' evaluation, you will only lose the confidence and credibility.


(My experience of giving a ‘bad’ evaluation to the buyer who are no response after the bid)

Online auction may have the potential digital hazard in the trade, as long as the concession of creating fake information, we may face the auction scam in the online shop.
