OUTPUT (monitor, printer, what else?) INPUT PROCESS OUTPUT Monitor Printer

Monitor Output Monitor resolution is called “soft copy” and is measured in pixel dimensions (e.g. 1280 x 1024) CRT displays are being replaced by flat screen technology

Connecting Display Devices standard monitor port S-video port Digital Video Interface (DVI) port

Connecting Display Devices

Printer Output Printer resolution is measured in dots per inch (dpi)
