A Computer Repair Technician is a person who repairs and maintains computers. The technician's responsibilities may extend to include building or configuring new hardware, installing and updating software packages, and creating and maintaining computer networks. Computer repair technicians work in a variety of settings, encompassing both the public and private sectors. Because of the relative newness of the profession, institutions offer certificate and degree programs designed to prepare new technicians, but computer repairs are frequently performed by experienced and certified technicians who have little formal training in the field. |
A private sector computer 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. Despite the vast variety of work environments, all computer technicians perform similar physical and investigative processes, including technical support. Experienced technicians might specialize in fields such as data recovery, system administration, or information systems. Some technicians are self-employed as freelancers or consultants. This type of technician ranges from hobbyists and enthusiasts, to those who work professionally in the field and either volunteer, or make a little side money.

The diagnosing of problems can range from a minor setting that is off, to spyware, and viruses, and as far as replacing hardware or an entire operating system.

Hardware repair

While computer hardware configuration varies widely, a technician works with two basic types of hardware: units limited to a location (desktops, mainframes and supercomputers) and more portable (laptop and handheld) devices. Technicians also work with and occasionally repair a range of peripherals, including input devices like keyboards, mice, and scanners, output devices like displays, printers, and speakers, and data storage devices ranging from external hard drives to specialized high-storage desktop computers called servers. Technicians involved in system administration might also work with networking hardware, including routers, switches, fiber optics, and wireless access points.

Hardware used

Software repair

If possible repair technicians protect the computer user's data and settings so after repair the user can fully use the device with little interruption, then solve the underlying software issue. Addressing the issue the technician could take action as minor as adjusting one or several settings or preferences, but could also apply more involved techniques like installing, uninstalling or reinstalling various software packages. A reliable but somewhat more complicated procedure for addressing software issues is known as the restore, in which the computer's original installation image (including operating system and original applications) is reapplied to a wiped and formatted hard drive surface.
