Topic: Everything Education / Jailor vs. Corrections

Hi everyone,
I just signed up for the deputy sheriff jailor civil service exam in Monroe County New York. I was wondering what the difference between a Deputy Sheriff jailor and a correction officer is? I know that the deputy sheriff jailor has a 16 week jailor academy and work for the county and that corrections officers work for the state and work for the DOC but what is the actual difference between the actual job duties?
