In today's world we encounter the technology at every step and everyone uses them. I think that technology makes our lives easier. Because we depend on them.Firstly, electronic gadgets make it easy to search for information,  for saving our time. For example, when we were leaving somewhere, we use the navigator to avoid getting lost in an unfamiliar place.Secondly, the technology enables us to communicate with each other at any distance. For example, e-mail allows us to quickly and cheaply send SMS to every corner of the earth. In addition, thanks to the Skype we can call anywhere and even see companion.On the other hand technology is not very safe and secure. They are often broken, can be lost or stolen.In conclusion, I want to say that technology is very important to us, so we must learn to master them.  It will be useful in the future.
