This chapter introduced some of the most common types of output devices in use today. You should have paid close attention to monitor types and their associated resolutions, colors, and technologies. At this point, you should also have a good understanding of dot matrix and laser printing technology, including the EP laser printing process. If you have trouble answering the review questions at the end of this chapter, go back and read the chapter again. If you want to pass the A+ Core test, you are going to have to master questions very similar to these questions relating to output devices.
