SharePoint offers excellent co-authoring capabilities thus making it possible for multiple users to work on a document without interfering with each other's changes. They can access the document at any time from anywhere using any device.
A column represents an attribute, or piece of metadata, that the user wants to manage for the items in the list or content type to which they added the column. Users can add columns to list, library and sites and even reference them in content types.
