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. 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.
