In Chapter 6, I learned about display devices, printers, CRT monitors, audio devices, and other types of input devices. Display devices can be monitors or televisions, and they come in Plasma and LCD. Liquid Crystal Display involved compressing hot liquid crystal in between two plates of glass, and when you shine light threw the crystal you result in an image. Also, I learned that printers come in two types non-impact and impact printers. Non-Impact often involves spraying ink on to paper. Ex. Inkjet. Audio devices are devices that produce or capture audio. Some of the devices that produce audio are headphones, speakers, and earbuds.
