It depends on the age of the vessel.
The older vessels had a rod going the length of the vessel which would stroke a steam steering gear, which would port steam to make the rudder go left or right. mechanical over steam.
Then there are still some, out there with the Tele-motor steering which is hydraulic over electric. There are hydraulic lines running the length of the vessel that in turns move the rudder hydraulically.
Finally there is electric over hydraulic.(Most vessels are operated this way) Electric signals start the motors which are mechanically linked to the pumps. There are other signals which make the rudder go left or right.
