Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems.

It is a far reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material or we can say virtual technology, such as computer software and business methods, fall under the definition of technology.

Technology has many effects. It has helped develop more advanced economies including today’s global economy. Its growth has allowed the rise of a leisure class. Many technological processes produce unwanted by products known as pollution and deplete natural resources to the detriment of earth’s environment. Innovations have always influenced the values of a society and raised new questions of the ethics of technology. Examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics.

Technology is defined as the applied science, quite different from pure science. This is the collection of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings.
