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.
Advantages of Random scan display:
1)high resolution
2)produce smooth line drawings.
Disadvantages of random scan display:
1)costlier
2)just does wire frame.
3)complex scene cause visible flicker.
Advantages of raster scan display:
1)decreasing memory costs have made raster systems popular.
2)high degree realism is achieved in picture with the aid of advanced shading and hidden surface technique.
3)Computer Monitors and TVs use this method
Disadvantages of Raster scan display:
1)the lines produced are zigzag as the plotted values are discrete.
2)resolution is low.
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming
Advantages: One of the cheapest forms of data storage. Disadvantage: low density (bulky), not random access (slow).
It can interact with a hidden periodic trait within a population hence the technique will be compromised since there will not be random and representativeness of the saple
Advantage -- Less effort, cost, work Disadvantage -- Less accuracy, information, difficulty of establishing true 'randomness" in some samplings.

lWhat are the advantages of ranking as a method of final choice over random selection?
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.
Your middle name does not have to be that of a relative, it could be from any family, or friends of your family, or simply something random.
