Everything in this world has its good side and bad side. For example, playing computer
games like Nintendo is very entertaining. You can play it when you are relaxing after studying or working. At the same time, it is entertaining and fun. However, there are times when playing these kind of games can be addicting. Even if you need to do something important, you still choose to play computer games. There are cases wherein children skip their meals just to play. Obviously, that's the bad side of it. This is not different in the case of WiFi or Wireless Fidelity.
The great help of WiFi in our lives is already a given. However, this mode of communication is very easy to penetrate. It can easily be accessed by anyone who has the knowledge about its weakness. Can you imagine this scenario? Two businessmen are talking to each other about a
certain code to transfer big amount of money to the bank account of the first businessman. Unfortunately, an intruder is also listening to their conversation. It was all too late as the two businessmen find out that the money was gone. If this thing happens to you, would you still be happy that WiFi was invented? I doubt it! So, be careful when you are communicating using wireless connection, because someone might be listening.
