Digital divide
A digital divide is an economic and social inequality with regard to access to, use of, or impact of information and communication technologies (ICT).[1] The divide within countries (such as the digital divide in the United States) may refer to inequalities between individuals, households, businesses, or geographic areas, usually at different socioeconomic levels or other demographic categories. The divide between differing countries or regions of the world is referred to as the global digital divide,[1][2] examining this technological gap between developing and developed countries on an international scale.[3]
