ITPEC IP October 2024 Question 25
ITPEC IP October 2024 — Question 25 of 100
Scanner resolution is commonly expressed in dpi, dots per inch. The value indicates how many samples or dots the scanner captures along one inch. A higher optical dpi can preserve finer spatial detail, although it also increases the number of pixels and file size, and interpolated resolution does not add true sensor detail.
Answer (a)
Why not others:
- (b) fps means frames per second and measures motion-video frame rate
- (c) pixel is an individual picture element, not a density per physical length by itself
- (d) ppm commonly means pages per minute for printer or scanner throughput
Key rule: dpi measures spatial sampling density; fps measures temporal frame rate, pixels count image elements, and ppm measures page-processing speed.
