Hardware repair
While computer hardware configuration varies widely, a repair technician will work with five general categories of hardware;
desktop computers,
laptops,
servers,
computer clusters and
smartphones /
mobile computing. 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 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.
Software repair
When possible, repair technicians protect the computer user's data
and settings, so that after repair, the user will not have lost any data
and can fully use the device with little interruption. 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 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.
