In our modern world, we all use the Internet for different purposes. We communicate with others, we watch videos, we play games, and we do a whole lot more. However, the Internet is not a safe place. We are not protected from malicious acts and we are not protected from unauthorized access. In fact, we are very exposed to all kinds of threats. 

In the same way that the Internet is not safe, neither is any other type of data. If you are trying to send data from one device to another, you will need to make sure that the data is not intercepted and that the transfer is not interrupted.
