What happens in the system after executing the command git push?

After executing the git push command, the following occurs:

1. The local Git client connects to the remote repository (for example, on GitHub or another server).
2. Transfer of changes: all commits present in the local branch but absent in the remote are sent to the server.
3. The remote repository updates its data by adding new commits to the corresponding branch.
4. If there are changes in the remote branch that are not in the local, the push may be rejected to avoid conflicts.

Thus, git push synchronizes local changes with the remote repository, making them accessible to other developers.
