A graphical terminal can affectation images as able-bodied as text. Graphical terminals are disconnected into vector-mode terminals, and raster mode.
A vector-mode affectation anon draws curve on the face of a cathode-ray tube beneath ascendancy of the host computer system. The curve are continuously formed, but back the acceleration of electronics is limited, the amount of circumstantial curve that can be displayed at one time is limited. Vector-mode displays were historically important but are no best used. Practically all avant-garde clear displays are raster-mode, descended from the account scanning techniques acclimated for television, in which the beheld elements are a ellipsoidal arrangement of pixels. Back the raster angel is alone apparent to the animal eye as a accomplished for a actual abbreviate time, the raster have to be active abounding times per additional to accord the actualization of a assiduous display. The cyberbanking demands of auspicious affectation anamnesis meant that clear terminals were developed abundant after than argument terminals, and initially amount abundant more.
Most terminals today are graphical - that is, they can appearance images on the screen. The avant-garde appellation for graphical terminal is "thin client". A attenuate applicant about uses a agreement like X11 for Unix-terminals, or RDP for Microsoft Windows. The bandwidth bare depends on the agreement used, the resolution, and the blush depth.
Modern clear terminals acquiesce affectation of images in color, and of argument in capricious sizes, colors, and fonts (type faces).
