Internet after its discovery in 1970's has become an important source for obtaining information as well as for communication. Since then it has been used in various fields like business, education, communication, marketing, research etc. However as a coin always has two sides, internet too has both advantages as well as disadvantages.
Firstly, if we look for advantages internet has made life very easy. Students can get every desired material for their studies from internet. They can find various reference books,different ideas for their projects online. Business people have professional sites like linked-in to make and maintain their professional relationships and share business ideas.If we talk about communication various social networking sites like Facebook,Twitter help people living in different parts of world to connect with each other. People share various news from different parts and their experiences and opinion about them. They can also do video chatting with their loved ones sitting in different parts of world.One can shop online sitting at home. We can buy whatever we want by just a single click on internet.Scientist communicate with their other colleagues and share researches online.
On the other hand Internet also has as many disadvantages as advantages.Students waste their time by playing games,chatting online and sometimes they look for websites which have unsuitable data for them.People sometimes misuse internet in offices and do unnecessary chatting and do not concentrate on their work which affects company's productivity.Sometimes we think we are talking to a friendly person on social networking site but that can be a dangerous stranger.Many a times there are network and connection problems with internet which affects work.It is is also difficult for old people to understand this new technology and use it.
So, to conclude, though internet is boon in every aspect in the present era but it has to be used with caution, care and intelligence. It is a sort of double edged sword that needs to be used carefully.
