A bitmap has no physical size (just a set number of pixels), until you specify the height and width
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A bitmap is a digital image format that is composed of a grid of pixels. Each pixel represents a specific color or shade, and when combined, they create the visual image. The bitmap itself does not have a physical size until the height and width are specified. This means that the number of pixels in the bitmap is fixed, but the actual physical dimensions can vary depending on how the image is displayed or printed. Therefore, the statement "A bitmap has no physical size until you specify the height and width" is true.Rate this question:

Vector files are usually larger than Bit-mapped files
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false. Bit-mapped files, also known as raster files, are usually larger than vector files. Bit-mapped files store information about each individual pixel in an image, resulting in larger file sizes. On the other hand, vector files use mathematical equations to define shapes and lines, resulting in smaller file sizes as they only need to store the instructions for rendering the image.Rate this question:
