I love fixing and maintaining computers.  So much so that I work as a computer repair technician.
Oh wow, that is what my father did, does it take a lot of schooling or training
They do have certificates and degrees in computer repair, but there are a lot of people that don't have much formalized training.
I see, they just work from their own self businesses. Do they make a lot of moeny
I think that the income can vary quite a bit.  Novice technicians do basic repairs, but experienced technicians can specialize in data recover, system administration, or information systems.
That makes sense, I bet they are able to work in a variety of different places
They do! If you look at just the public sector, a computer repair technician can work in law enforcement, the military, health or public safety, or at educational institutions!
That could be a good career to go to school for, so much variety and chance to make a lot of money! Have they been around for a long time?
I'm not certain when the field actually started.
I see, I guess probably as long as computers have been around
