Ques:- How do Git internals work (objects, refs, trees, blobs)?
Right Answer:

Git internals consist of four main components:

1. **Objects**: Git stores data as objects, which include blobs, trees, commits, and tags. Each object is identified by a SHA-1 hash.

2. **Blobs**: These are binary large objects that store the content of files. Each file's content is stored as a blob.

3. **Trees**: Trees represent directories and contain references to blobs (files) and other trees (subdirectories). They maintain the structure of the repository.

4. **Refs**: Refs are pointers to commits. They include branches and tags, allowing Git to track different versions of the project.

Together, these components enable Git to efficiently manage version control and track changes in a repository.

Ques:- What is Git and why is it used
Right Answer:

Git is a distributed version control system used to track changes in source code during software development. It allows multiple developers to collaborate, manage code versions, and maintain a history of changes efficiently.

Ques:- What’s the difference between git pull and git fetch?
Right Answer:
