Display Devices ,[object Object],Step 1: The processor sends digital video data to the video card. Step 2: The video card’s digital-to-analog converter (DAC) converts the digital video data to an analog signal. Step 3: The analog signal is sent through a cable to the CRT monitor. Step 4: The CRT monitor separates the analog signal into red, green, and blue signals. Step 5: Electron guns fire the three color signals to the front of the CRT. Step 6: An image displays on the screen when the electrons hit phosphor dots on the back of the screen. p. 6.10 Fig. 6-10 Step 1 Step 1 Step 2 Step 1 Step 2 Step 3 Step 1 Step 2 Step 4 Step 3 Step 1 Step 2 Step 3 Step 4 Step 5 Step 2 Step 3 Step 4 Step 5 Step 6 Step 1 Next

Printers ,[object Object],Step 1: The drum rotates as gears and rollers feed a sheet of paper into the printer. Step 2: A rotating mirror deflects a low-powered laser beam across the surface of a drum. Step 3: The laser beam creates a charge that causes toner to stick to the drum Step 4: As the drum continues to rotate and press against the paper, the toner transfers from the drum to the paper. Step 5: A set of rollers uses heat and pressure to fuse the toner permanently to the paper. p. 6.17 Fig. 6-23 drum rotating mirror drum rotating mirror drum rotating mirror drum rollers rotating mirror drum Next
