Appendix I – I/O and Multimedia Devices Worksheet 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 or graphics cards. Before you can 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 or graphics card in high-end PCs, especially those that require more than one monitor. In this situation, the graphics cards are needed to handle more graphics, 3D rendering, and gaming applications. This worksheet will help you practice your research skills in finding appropriate I/O devices. Activity: Product Search Your office wants to upgrade their computers with a graphics/video card. Their computers are the same as the one featured in the Computer Hardware Simulator (CHS). Search the Internet for two different graphics cards and video cards that would work with the computers.
