What is difference between git diff and git status?

How git diff works internally?
In fact, it runs it twice, or more precisely, it runs two different internal variations on git diff : one to compare HEAD to the index/staging-area, and one to compare the staging-area to the work-tree. It runs each diff with a request to search for renames, i.e., sets the -M flag (see below).
How does GitHub calculate diff?
Computing diffs
The diff is dynamically generated from the snapshot data by comparing the root trees of the commit and its parent. Git can compare any two snapshots in time, not just adjacent commits. To compare two commits, start by looking at their root trees, which are almost always different.

In Git, “origin” is a shorthand name for the remote repository that a project was originally cloned from.
