Computer technicians work in a variety of settings, encompassing both the public and private sectors. A repair technician might work in a corporate information technology department, a central service center, or a retail computer sales environment.
A public sector technician might work in the military, national security or law enforcement communities, health or public safety field, or an educational institution.
