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 networks.
