diff can be used to compare different files.
It gives the position where difference between the 2 files which are compared 
exists.

viewing what all changes have been made to the file.

One commit per logical change

Manual is good but it should be done by taking in to consideration "ONE commit
per logical changE.

project. A collection of files is called a "REPOSITORY" in git,
whenever a commit is made to a file in a project revision is made to all the 
files in that project for proper functioning of that project.
