Technology is the collection of any methods, skills, practices, and procedures employed in the development of new products or services or in the achievement of specific goals, for instance scientific research. There are different types of technology. For instance technological change is the application of scientific knowledge to changes in production, information, processes, and organizational structure. Others include information technologies, computer sciences, energy sciences, physical sciences, engineering, software sciences, telecommunications, and networking technologies. There is also a broad category of associated fields, e.g., information systems, health informatics, product development, and systems analysis.

In order to understand technology, one must first understand the difference between the various forms of technology that fall under the broad categories noted above. For instance, while technological change refers to the application of scientific knowledge to changes in production, information, processes, and organizational structure, knowledge is broader and more inclusive. Knowledge also includes the knowledge needed to evaluate a technological product, such as whether it is likely to meet a customer’s needs or whether it is likely to be safe. On the other hand, the three forms of technology mentioned above are part of the large family of human disciplines known as practical sciences. Practical sciences include art, architecture, physical sciences, engineering, and medical science.

To understand technology, one must learn about the different disciplines that make up this broad group of human knowledge. Theoretical study of technologies provides knowledge of how theoretical sciences and physical sciences and social science affect each other. It also gives an account of how technological systems are designed, developed, and maintained. Practical studies of technologies allow people to practice and try different practical applications of theories and to gain insight into how different technological innovations have affected societies and the world as a whole.
