Document and file collaboration are the tools or systems set up to help multiple people work together on a single document or file to achieve a single final version. Normally, this is software that allows teams to work on a single document, such as a word processor document, at the same time from different computer terminals or mobile devices. Hence, document or file collaboration today is a system allowing people to collaborate across different locations using an Internet, or "cloud", enabled approach[1] such as for Wikis such as Wikipedia.
