Collaboration tools have must facilitate sharing content and communications. How can we differentiate content and communications?

Communications $($in this context$)$ are strictly messages between specific project members and are never shared with the group, and shared content is generally communication for the entire group, particularly the products of meetings, es$.$ video recordings or meeting notes

Communications are messages between project members $($possibly including many project members at once, and may include feedback; shared content is less about communicating with members, and focuses on things such as documents, files, schedules, and work products

In practice, there is little to differentiate the two, and both are listed to emphasize the versatility of collaboration information system products

Communications are never very large, e$.$g$.$ a few bytes, and shared content is always huge, usually on the order of gigabytes
