                    Unit 8 – Installing and Supporting I/O Devices

Unit Organizer:
A statement or question that:
     Focuses on realistic issues or problems
     Communicates the content standards in a way that engages students
     Connects learning to prior knowledge, experiences, skills, beliefs, and customs

       Unit 8 covers how to install and support I/O devices. The introductory sections
       describe various types of external input devices, such as keyboards, computer
       mice, and barcode scanners. Discussion of output devices, such as monitors and
       projectors logically follows. All of the I/O devices mentioned connect to the
       computer system via one of two ports: a port off the motherboard or a port
       provided by an expansion card. The middle sections of the chapter are dedicated
       to presenting ports falling into each of these categories. Students are also shown
       how to install USB devices, IEEE 1394 devices, and expansion cards. The final
       sections provide recommendations for troubleshooting I/O devices.

          expensive than VRAM. It has its own internal bus on the chip, with a data
          path that is 256 bits wide.
