Question - 97 : - What is the difference between git reflog and log?
Answer - 97 : -
The git log is a public record of the commit history for a branch. Reflog, on the other hand, is a private one of the repository’s local commits.
Unlike reflog, the git log is a part of the Git repository and is replicated after a push, fetch, or pull. A developer cannot access a local repository’s reflog without having access to the computer where it is located.
Question - 98 : - How are fork, branch, and clone different from each other?
Answer - 98 : -
Forking creates a copy of the original repository, and it remains in the GitHub account. Whereas, in cloning, the repository is copied to the local machine using Git. Forking is used to propose changes to the repository owners. In cloning, the changes are directly pushed to the original repository, provided the user has write access. A branch occurs within a repository and is a way to keep developing and modifying the software without affecting the main project.
