computer screen resolutions are 640 x 480 pixels (VGA resolution; appropriate for a 14-inch

 

screen), 800 x 600 (appropriate for a 15-inch screen), 1,024 by 768 (appropriate for a 17-inch

 

screen), and 1,280 by 1,024. LCD displays usually use a higher resolution than a CRT of the

 

same size.

RGB stands for Red, Green, Blue. A cable that requires separate transmission types for the

 

three colours on the display.

recover the hard disk image that was available when the computer was purchased.

supported by one to four transistors.

occurs, you have time to save all unsaved data and to shut down your computer.

mouse, joystick, scanner or printer). You can connect up to 127 devices to a USB port. The
