What is version management and why is it important?

 Every collaborative project involves sharing of content. Although email is simple, easy, and readily available, it will not suffice for collaborations in which there are many document versions or for which there is a desire for content control. Storing documents on servers is better than using email attachments because documents have a single storage location. They are not scattered in different team members' email boxes. However, without any version management it will be impossible to know who changed the document and when. Version management is a technique used for sharing electronic content. Systems that provide version management track changes to documents and provide features and functions to accommodate concurrent work. Google Drive and Microsoft One Drive are examples of systems that provide version management.

Tremendous help, I just double-checked it with my friend
