Internet: The Intangible World



In the 21^st century, the term “internet” certainly isn’t something unfamiliar to most people in today’s society. Whether it’s children or adults, whether it’s students or professionals, they have all benefited significantly from the internet. It is an unquestionable fact that internet has bought so many privileges and also changes into the lives of many. For instance, people have easier access to a variety of information because of internet. Before internet is introduced, people might have difficulties finding information. Sometimes, they might have to visit a variety of places just to find the right information. This is not only timely, but it can also be very costly. Now, due to the existence of internet, those problems can be simply resolved. Without any trouble, researchers can effortlessly find the information they need from reliable sites and/or online documentations. Furthermore, internet makes communication to one another simpler and faster. As long as a person is on a computer where internet access is provided, he/she will have no difficulties even talking to someone who is on the other side of the world. Other devices that make the conversation more entertaining are webcams and microphones-- what’s the point of making long-distant phone calls then? Talking online makes communication incredibly convenient.

Apparently, internet might seem to be a useful tool to the majority, disadvantages and potential danger do come along. The internet can be a disrupting place for young children. Chat rooms and other inappropriate sites can be extremely dangerous and risky once private information is exposed. If the parents fail to keep an eye on their children, chatting or meeting with strangers can cause devastating impact on the child’s life. Another disadvantage of internet is dependency. Since it is assumed that internet might have an answer for everything, people, particularly students might come to internet as a way to seek for an answer. Thus, they will never be able to recognize the importance of developing their own unique thoughts. In doing so, they lose the ability to think, or even perform tasks independently on their own.

The existence of internet not only brings in changes, it also implies challenges. Internet is a place where freedom of speech is permitted. One can express any opinions without any restraint. What this signifies to some individuals is that, they can post any irresponsible or disrespectful speeches if they want because there is no one to draw the line. It requires certain amount of courage and bravery to stand up for something in real life, yet hiding behind the keyboards to insult others, is way easier. Last of all, although internet has offered people with enjoyments and benefits, this can supposedly put many industries out of business. It is known that some sites on the internet offer free downloading of music and movies in a quick and easy manner. People can easily sit back and enjoy this free service without even having to pay for it. On the surface, this seems to be a perfect deal, but the real problem arises-- what’s the point of visiting a music store and buying a CD album? What’s the point of buying or renting a movie? While this issue can also interfere with so many other problems such as copyrights. Yet it is not stopping.
