Why is the eighteenth question a D?

Dot-pitch (or fringe pitch) is a very important hardware metric for a display. The so-called point distance refers to the distance between a luminous point of a given color and its nearest adjacent luminous point of the same color, which cannot be changed with software, which is different from resolution. At any same resolution, the smaller the pixel pitch, the sharper the image, as is common for 14-inch displays

And; The so-called stripe spacing refers to the color point of some monitors using stripes instead of standard CRT, compared with the color point, the resulting image is brighter and clearer, and the stripe spacing is generally in between, which is more expensive than ordinary displays.

Hehe, I'm here too.

Clearer. Point distance refers to the distance between two adjacent pixel cells of the same color on the screen, that is, the distance between two red (or green, blue) pixel cells.

The smaller the dot spacing, the more comfortable the image will look and the less pronounced the aliasing will be.

The smaller it is, the clearer it is, and the more detailed it is.

The higher the point distance, the more pixels in the unit area of the display, the higher the resolution, and the clearer the display details.

1 All x = 3, y = 5Obviously, (3>5) is false, (5>0) is true, and false and true or true, i.e., 0 or 1=1

a: The logical operation and should be both true values, -3+5=2, 2b: eqv: perform the logical equivalence operation of the two expressions, x<0 is false, y>0 is true, so it is not equivalent, and the expression value = 0

c:or, or operation, as long as one of them is true, although x>y is false, but the following y>0 is true, so the expression value = 1.

The answer comes out, choose C.

Suppose that the figure is white, dark gray, and light gray, which are coded by 1 byte. The image is composed of 32 rows and 9 columns of pixels, so the image is scanned from left to right and top to bottom

White: 173 in a row. Occupies 2 bytes.

Dark gray: 5 in a row, occupying 2 bytes.

White: 26 consecutive, occupying 2 bytes.

Dark gray: 1 in a row, occupying 2 bytes.

Light gray: 5 in a row, occupying 2 bytes.

Dark gray: 1 in a row, occupying 2 bytes.

White: 23 consecutive, occupying 2 bytes.

Dark gray: 2 in a row, occupying 2 bytes.

Light gray: 7 in a row, occupying 2 bytes.

Dark gray: 18 consecutive, occupying 2 bytes.

White: 5 in a row, occupying 2 bytes.

Dark gray: 1 in a row, occupying 2 bytes.

Light gray: 25 in a row, occupying 2 bytes.

Dark gray: 1 in a row, occupying 2 bytes.

White: 1 in a row, occupies 2 bytes.

In summary, the total number of bytes encoded by RLE is 30 bytes.
