Easy Computer Basics, Windows 7 Edition

Your computer electronically transmits words and pictures to your monitor. These images are created by a video card installed inside your system unit. Settings in Windows tell the video card and the monitor how to work together to display the images you see on the screen.

NOTE

CRT Versus LCD

Many lower-priced systems use traditional cathode ray tube (CRT) monitors. Newer flat-screen monitors use an LCD display instead, which takes up less desk space.
