ITPEC FE Morning April 2023 Question 73
ITPEC FE Morning April 2023 — Question 73 of 80
Digital Signage — identify the correct definition among similar "digital" terms.
Digital signage is an electronic billboard that displays information such as images, video, and characters in public spaces (airports, malls, stations).
Why not others:
- (a) — describes digital watermark (embedding identification info to prevent abuse)
- (b) — describes digital divide (economic/social gap due to lack of IT access)
- (d) — describes digital signature (ensures validity/authenticity of information)
Key rule: Don't confuse digital signage / signature / watermark / divide — all start with "digital" but have completely different meanings.
