PC Systems Building & Software Installation Computer Video Terms Refresh – (vertical scan rate) the time it takes to fill the screen from top to bottom, standard rate 70MHZ Interlaced – two passes to draw a screen even lines/odd lines, slow rate and have a slight flicker Non-interlaced – one pass to draw screen low flicker Dot Pitch – distance between dots (red,green,blue) smaller in size better picture .28mm/.25mm the best. .35mm/.38mm low res. Resolution – the number of spots that is actually accessed by the software. Pixel – is the area that produces the image low-high res, standard is 800 x 600 and high 1024 x 7 Multiscan Monitor – provide many varieties of vertical and horizontal refresh rates, expensive. Green Monitor – meets EPA Energy Star program & use 100 to 150 watts of electricity. When saver is on uses only 30 watts. Vesa – video electronics standards association Video RAM – data stored in memory of the video card DRAM – dynamic random access memory - standard VRAM – video random access memory – faster MDRAM – multi dynamic access memory – uses a full 128 bit path SGRAM- synchronous graphics random access memory, designed for video card processing, improves performance by interacting with CPU bus clock WRAM – Window random access memory – less expensive 3D-Ram – memory is embedded in microprocessor and improves performance 640 x 480 res – number of pixels that make up the image for a standard monitor 800 X 600 res – number of pixels for standard software applications 1024 x 768 res – number of pixels that make up the image for high performance monitor CRT – cathode ray tube MGA – monochrome graphics adapter CGA – color graphics adapter VGA – video graphics array SVGA – super video graphics array LCD – liquid crystal display Computer Video Terms Refresh – Interlaced – Non-interlaced – Dot Pitch – Resolution – Pixel – Multiscan monitor – Green monitor – Vesa – Video RAM – DRAM – VRAM – MDRAM – SGRAM – WRAM – 3D-RAM – 640 x 480 res – 800 x 600 res – 1024 x 768 res – CRT – MGA – CGA – VGA – SVGA – LCD – PC Systems Building & Software Installation Name_____________________ Computer Video Terminology Assessment Exam Date______________________ Part A – True or False (Use a T for True or F for False) ___ 1.
