Tai iki šiol linko nepaskaitei? Gi, nuo pat pirmų sakinių viską paaiškina:


The cathode ray tube (CRT) is a vacuum tube that contains one or more 
electron guns and a phosphorescent screen, and is used to display 
images. It modulates, accelerates, and deflects electron beam(s) onto 
the screen to create the images.
