digital divide

The gap between those who have access to digital technologies and those who do not; or the gap between those who use digital technologies and those who do not. Patterns of unequal access are often related to global inequalities and to individual factors such as income, age, and/or gender issues. Often treated as a synonym for the knowledge gap between the information rich and poor.
Digital divide is marked not only by physical access to computers and connectivity but also by access to the additional resources that allow people to use technology well.
The concept of a digital divide gained headway in the mid-to-late 1990s, at the same time that the Internet and dot-com booms were under way in the United States.
