The Internet is one of the best gifts of science. It has made our life and lifestyle much easier than before. It is playing a significant role in the concept of globalization. It is being used in almost every sphere of life considering its positive aspects. But, it has some negative aspects too. ‘Internet’ is the abbreviation of ‘International Network’. It is actually an international computer network connecting other networks and computers around the world. To have access to Internet, four things are needed. These are computers, Modem, Telephone connection, and Internet service, provider. It is now possible through Internet to send or receive information to or from any part of the world. Books are essential for study and research. But they may not be available every time. Internet can solve this problem. We can get access into any library of the world to search for necessary information. Internet also helps travelers giving information about the environment of the spot and making arrangements for air tickets, hotel booking, etc. Internet also helps the patients to get prescriptions and treatment of the famous doctors at a minimum cost. We can get important news of home and abroad from it. On the other hand, Internet provides us with opportunities to enjoy music, movie, sports, etc. In a word, it can be said that Internet plays a very important role in different fields of our life including trade and commerce, education and recreation and above all effective communication.
We can’t deny the fact that internet has brought a revolutionary change to our lifestyle, but we can’t ignore the disadvantages of internet. First of all, a person we spend too much time in from of the computer may fall ill. It may damage his/her eyesight. On the other hand, sometimes internet can provide us with wrong information. Because in internet or web anyone can post any information. So sometimes wrong information can also be posted in internet. Again hackers may post malicious links and can cause harm to our confidential data. Different terrorist groups also use Internet facilities for their terrorist activities. However, all these refer to the wrong use of the Internet. The Internet system is, in no way, responsible for these problems. One of the most dangerous disadvantages of the internet in today’s time is the fraud business. With the popularity of the internet, we can see rapid growth in fraud business.
