In addition to solving problems involving computer systems, operating systems, application software, and networks, you need to be familiar with the peripheral devices typically used in a business setting similar to Plaid. These include various input and output devices, including mice, tablets, scanners, printers, projectors, and display systems. While it is impossible to know each of these systems intimately, you should generally know how they work, the problems they may encounter, and how to resolve these. As in any support role, you should also be able to quickly describe how you would research the information needed to resolve an issue you are not familiar with.
