1.What is the difference between bundle and bundle update?

Ans :
bundle is the same as bundle install, which does the following:

• Check if a Gemfile.lock exists. If it does, install all gems with the exact versions specified there.
• If the lock doesn't exist, install gems as specified in the Gemfile, using the latest available / allowable versions according to the Gemfile. Then create the Gemfile.lock to record what versions have been installed.

bundle update on the other hand, deletes / ignores your Gemfile.lock and goes straight to step two.
