Educational technology is the combined use of computer hardware, software, and educational theory and practice to facilitate learning. When referred to with its abbreviation, "EdTech," it often refers to the industry of companies that create educational technology. In EdTech Inc.: Selling, Automating and Globalizing Higher Education in the Digital Age, Tanner Mirrlees and Shahid Alvi (2019) argue "EdTech is no exception to industry ownership and market rules" and "define the EdTech industries as all the privately owned companies currently involved in the financing, production and distribution of commercial hardware, software, cultural goods, services and platforms for the educational market with the goal of turning a profit. Many of these companies are US-based and rapidly expanding into educational markets across North America, and increasingly growing all over the world."

M-learning, or mobile learning, is a form of distance education where learners use portable devices such as mobile phones to learn anywhere and anytime. The portability that mobile devices provide allows for learning anywhere, hence the term "mobile" in "mobile learning." M-learning devices include computers, MP3 players, mobile phones, and tablets. M-learning can be an important part of informal learning.
