The best definition of technology is the study and transformation of techniques, tools, and machines created by humans. Technology allows humans to study and evolve the physical elements that are present in their lives.
We can study the technology of a car engine, the technology of television, and the technology of a job or art. Nature can not be considered as a technology because humans did not have any role in its creation. They can transform it on the surface, but not deeply. In this case, we call it a science.
Science is a theoretical knowledge that man seeks to master to understand the working and the link that exists between different natural phenomena. On the contrary, technology is practical knowledge that is alive. We study technology to improve the observed object. It is an activity that is always moving. On the contrary, science is frozen in time. The science of mathematics has not changed much in centuries. The concepts have remained the same. For example, the technology of a mobile phone did not exist 100 years ago. It is the engineers who invented it.
