.....altitude manually, or is it the computer who is making this?

Most airliners use an automatic pressure controller. In the more sophisticated airplanes, the navigation database knows the elevation of the destination airport and everything is handled automatically. In other slightly less sophisticated airliners the crew will set in the elevation of the destination airport and the rest is automatic.
The automated systems change the altitude at a rate of less than 500 feet per minute. You'll sometimes feel your ears pop, but unless you have some sort of head/ear congestion it shouldn't be painful. Babies and young children are sometimes more sensitive. It helps to give them something to chew or suck on to help equalize the pressure.
In smaller planes the crew must set in a cruise altitude and then remember to set in the elevation of the destination airport when they begin a descent. On top of this, the crew can control how quickly the cabin altitude climbs or descends.
All these systems have a manual override function, but there are still limits of what the pressurization system can do and what the aircraft structure will tolerate.
Airliners are typically capable of somewhere around 8psi of pressurization (some a little more, some a little less). The designers usually shoot for something near an 8,000 foot cabin altitude at the aircraft's maximum cruising altitude.
You'll usually experience a cabin altitude of between 5000 and 8000 feet when riding in a jet airliner. This is approximately the equivalent of what you'd feel in Denver on a summer day.
Hope this helps!

Cabin altitude is adjustible from the cockpit.
There might be a maximum differential pressure
limit by the time you get to FL360+.

8,000ft.
Yes the pilot can change the altitude. On most aircraft there is a Manual and Automatic setting for the Pressure controler. Most checkslist list the Pressure control as Auto to save pilot workload.

Roughly the same altitude as the cockpit.
Just a guess !

Around 8000 ft...or 750mb...and is normally preset but is adjustable from the cockpit.

about a mile up . and yes you can ... take your foot and bust out a window.. instant change in cabin pressure
