The digital divide refers to the gap between people with access to digital technology and those without. It includes differences in physical access to technology as well as the skills needed to use technology. Examples of digital divides include differences in access between wealthy and poor people, men and women, disabled and non-disabled people, and developed and developing nations. Efforts to close the digital divide focus on increasing affordable access to computers and the internet through open source software, availability in schools, and making technology more generally accessible.
