A repair technician might work in a corporate information technology department, a central service center, or a retail computer sales environment. The repair of problems can range from a minor setting that is incorrect, to spyware, viruses, and as far as replacing hardware or an entire operating system. A computer repair technician is a person who repairs and maintains computers and servers. The technicians responsibilities may extend to include building or configuring new hardware, installing and updating software packages, and creating and maintaining computer networks. A technician will work with five general categories of hardware such as desktop computers, laptops, servers, computer clusters and smart phones or mobile computing. They also work with an occasionally repair a range of peripherals including input devices., output devices and data storage devices such as internal and external hard drives and disk arrays. Technicians involved in system administration might also work with networking hardware including routers, switches, fiber optics and wireless networks. A reliable, but somewhat more complicated, procedure for addressing software issues is known as a restore, in which the computer's original installation image including operating system and original applications is reapplied to a formatted hard drive. It should be known though, that anything unique, such as settings, or personal files will be destroyed if not backed up on external media, as this reverts everything back to its original unused state.
Experienced technicians might specialize in fields such as data recovery, system administration or information systems. Some technicians are self-employed or own a firm that provides services in a regional area.
Some are subcontracted as freelancers or consultants. This type of technician ranges from hobbyists and enthusiasts that volunteer or make a little side money, to those who work professionally in the field.
