Technology involves a wide range of tools, materials and processes that allow humans to manipulate their environments. Technology also includes the means for transferring information from one person to another.

It can be divided into categories based on how it is used, what problems it solves and the purposes it serves. For example, educational technology encompasses the use of digital devices and resources to support student learning. This can include websites like Spelling Training, which allows teachers or students to upload word lists and practice spelling and phonetic skills in interactive games.

Science and engineering are often considered to be forms of technology, although there is a distinction between science as an activity and technology as a tool. Scientists study phenomena and develop new knowledge, while engineers apply this understanding to create technological products and systems.

The development of technologies is typically a step-by-step process, with each step validating and testing the ideas behind the invention. This is why apparently promising early technologies often stall midway through their development. It is also why technology can be difficult to manage, as it requires a large investment of time and money in order to function properly. However, when it is employed effectively, technology can be a boon to productivity. For example, automation tools can reduce manual calculations and data analysis and provide a higher level of accuracy. Similarly, communication technology can enable organizations to streamline their internal communications and collaborations. This can lead to increased productivity across departments and businesses.
