Appendix J

I/O and Multimedia Devices

As a computer technician, you must be familiar with a wide range of input/output (I/O) devices, including keyboards, mice, monitors, biometric devices, projectors, cameras, and video cards. Before you attach any of these to a computer system, you must first research which I/O devices and expansion cards are best suited for your computer’s configuration; for example, it is common to find more than one video card in high-end PCs, especially those that require more than one monitor. In this situation, video cards are needed to handle more graphics, 3D rendering, and gaming applications. The appendix helps you practice your research skills in finding appropriate I/O devices.


Your office wants to upgrade its computers with a video card. Their computers are the same as the one featured in the Computer Hardware Simulator (CHS). Search the Internet for two video cards that would work with the computers.

Use the CHS Reference Chart to record the current components found on the CHS computer:
