coed

Mixed-sexed education, also known as mixed-gender education, co-education or coeducation (abbreviated to co-ed or coed), is a system of education where males and females are educated together. Whereas single-sex education was more common up to the 19th century, mixed-sex has since become standard in many cultures, particularly in Western countries. Single-sex education, however, remains prevalent in many Muslim countries. The relative merits of both systems have been the subject of debate.

The COED Project, or the COmmunications and EDiting Project, was an innovative software project created by the Computer Division of NOAA, US Department of Commerce in Boulder, Colorado in the 1970s. This project was designed, purchased and implemented by the in-house computing staff rather than any official organization.
