title: What's the difference between 'Commit ID' and 'SHA1 Hash' in GIT?
body: <p>I've been working on GIT for quite sometime now.</p>
  
  <p>However, I could not find difference between 'Commit Id' and 'SHA1 - hash value'</p>
  
  <p>What is the difference between 'Commit ID' and 'SHA1'?  Any simple explanation with an example would be nice</p>
