Introduction
What do you think of when you hear the word technology? Do devices like computers and solar-powered cars come
to mind? Devices such as these are just one meaning of the term "technology." As a field of study, technology is
much broader than that.
What Is Technology?
Technologyis the application of knowledge to real-world problems. It includes methods and processes as well
as devices like computers and cars. An example is the Bessemer process. It is a cheap method of making steel
that was invented in the 1850s. It is just one of many technological advances that have occurred in manufacturing.
Technology is also responsible for most of the major advances in agriculture, transportation, communications, and
medicine. Clearly, technology has had a huge impact on people and society. It is hard to imagine what life would be
like without it.
Professionals in technology are generally calledengineers. Most engineers have a strong background in physical
science. There are many different careers in engineering. You can learn about some of them at the URLs below.
