– the bigger the size of the LCD monitor or screen then the higher the resolution of the monitor
2. HDTV features:
– working with digital broadcast signal transmitting digital sound ,supporting wide screens provide resolution up to 1920 x 1080 pixels
– the console game user often use television for it’s output by connecting the device video port on the television.
3. –The two type of printing technology are Bluetooth and Infrared.
– With Bluetooth printing, a computer or other device transmits output to a printer via radio waves.  The computer or other device and the printer do not have to be aligned with each other; rather, they need to be within an approximate 30-foot range. while infrared printing, a printer communicates with a computer or other device using infrared light waves.
