CTRL+Z stops (pauses) a job

CTRL+C terminates a job

with CTRL+C you cannot resume the process but with CTRL+Z the job can be resumed by just entering at the command promt:

fg %1

if you have multiple processes paused then you should do

jobs

to see the output and select the appropriate number to resume e.g.

fg %3

resumes the third job in the list. You can also have jobs running in the background with

bg %n

where n is the job number.
