TASK I Careers in IT

Careers: Computer Technician

Computer technicians repair and install computer components. They may work on everything

from personal computers and mainframe servers to printers. Some computer technicians are

responsible for setting up and maintaining computer networks. Experienced computer technicians

may work with computer engineers to diagnose problems and run routine maintenance on complex

systems. Job growth is expected in this field as computer equipment becomes more complicated and

technology expands.

Employers look for those with certification in computer repair or associate degrees from

vocational schools. Employment usually begins with training, but most employers expect applicants

to have prior technical experience. Computer technicians also can expect to continue their education

to keep up with technological changes. Good communication skills are important in this field.
