Which of the following is NOT one of the four main categories of technology?

In the context of the four main categories of technology, information, transportation, and manufacturing are all fundamental areas that encompass a wide range of applications and systems.

Information technology involves the use of computers and telecommunications for storing, retrieving, and sending information. Transportation technology deals with the design and operation of vehicles and infrastructure that allow for the movement of people and goods. Manufacturing technology focuses on the processes and systems used to produce goods, from raw materials to finished products.

Entertainment, while it is indeed a significant aspect of modern society and heavily incorporates technology, does not fit into the traditional categorizations of technology that focus primarily on facilitating essential services and functions. Therefore, it does not align with the core categories that define technology’s role in society as recognized in educational contexts.
