MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Answer: b Explanation: The ratio of vertical points to horizontal points and horizontal points to vertical points is known as an aspect ratio.

Detailed explanation-2: -The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side-the ratio of width to height, when the rectangle is oriented as a “landscape".

Detailed explanation-3: -The two most common aspect ratios are 4:3, also known as 1.33:1 or fullscreen, and 16:9, also known as 1.78:1 or widescreen. (Larger aspect ratio formats are used in the motion picture industry.) All the older TV’s and computer monitors you grew up with had the squarish 4:3 shape– 33% wider than it was high.

Detailed explanation-4: -The 2:1 aspect ratio is a TV and film standard. It has an aspect ratio that is twice as wide as it is tall (2:1), so it has a width-to-height ratio of 2 units to 1 unit. TV screen resolutions are measured in inches of height per unit of width, so a 2:1 widescreen TV or film will have a 16:9 resolution.

Detailed explanation-5: -2:3 is the most popular aspect ratio for printing. Print sizes that are a 2:3 aspect ratio and are popular with poster, canvas, and decal printing are 24 x 36 inches and 40 x 60 inches. Some popular print sizes for the 3:4 ratio includes 30 x 40 inches and 18 x 24 inches.
