Question

Two developers on your team are editing the same project files at the same time, and previously they overwrote each other's work by emailing files back and forth. A colleague suggests adopting a version control system like Git. Which core capability of version control most directly solves their problem of losing each other's changes?

Accepted Answer

It records every change as a tracked history so multiple contributions can be combined and no work is silently overwritten

Answer

It automatically deploys the application to production whenever a file is saved

Answer

It compresses the project files so they take up less disk space when shared

Answer

It encrypts the source code so only authorized developers can open the files
