mv just update a pointer in the filesystem whereas cp does that and copy so mv is faster

The one comand moves the file, delete it, and copy to new location. Cp -copyes the file and the source of the file states on  it's plays.

mv across a filesystem boundary means copying (possibly under a new name)  then deleting the source file, cp is always just a copy (possibly under a new name) without any deletion.

mv inside a filesystem just updates the directory inode(s) with the new file location (and possibly a new name) and doesn't displace any data.

mv inside a directory is always just a rename operation.

cp will always copy file to another

mv could mean:

move file from one place to another (same dir or different dir or filesystem)

rename file
