Applications of random scan display system?
ecg
What is the use of display file in random scan system?
Display File is a memory area which stores picture definition as a set of line drawing commands.Video controller interprets these commands and produces actual image on the screen.Display File in random scan system is comparable to frame buffer in raster scan system, on the basis of their functions.
What is random scan display in CRTcomputer?
In random scan display the electron beam is directed only to the part of the screen where the picture is to be drawn. Random Scan monitor draw one picture at a time therefore they are also known as vector display.refersh rate or random scan system depends on the number of times to be displayed. Picture definition is stored in an area of memory called refresh display file.
Where in use random scan?
plen plotter is most example of random scan display
Is raster scan displays same as bit-mapped displays?
raster scan display -based on television technology.where as random scan display based on hard copy devices.raster scan display cannot directly pass electron beam through the scan line..but random scan directed the beam toward the scan line.
What are the relative advantages and disadvantages of random scan and raster scan display system?
Raster-scan system:-1)raster displays have less resolutio. 2)the lines producced are ziz-zag as the plotted values are discrete.3)high degree realism is achived in picture with the aid of advanced shading and hidden surface technique.4)decreasing memory costs have made raster systems popular.Random scan system:-1)random displays have high resolutions since the picture definition is stored as a set of line drawing commands and not as a set of intensity values. 2)smooth lines are produced as the electron beam directly follows the line path.3)realism is difficult to achieve.4)random-scan system's are generally costlier.

Compare the merits and demerits of raster and random scanning system?
Raster-scan system:-1)raster displays have less resolution.2)the lines produced are ziz-zag as the plotted values are discrete.3)high degree realism is achived in picture with the aid of advanced shading and hidden surface technique.4)decreasing memory costs have made raster systems popular.5)In this case, the electron beam is swept across the screen, one row at a time from top to bottom.6)Picture definition is stored in a memory area called the refresh buffer/frame buffer.7)Refreshing on raster scan displays is carried out at the rate of 60 to 80 frames/second. Random scan system:-1)random displays have high resolutions since the picture definition is stored as a set of line drawing commands and not as a set of intensity values.2)smooth lines are produced as the electron beam directly follows the line path.3)realism is difficult to achieve.4)random-scan system's are generally costlier.5)Here CRT has the electron beam directly only to the parts of the screen where a picture is to be drawn.6)Picture definition is stored as a set of line drawing commands in an area of memory referred to as refresh display file.7)Random scan systems are designed to draw all the component lines of a picture 30 to 60 times each second.
How does random scan display works?
it blows up your computer. SORCE i have shrapnal in my eye
How do you know why the engine management light is on and how to fix it?
Step one is to have the system checked with a scan tool.Step one is to have the system checked with a scan tool.
