ITPEC IP April 2018 Question 25
ITPEC IP April 2018 — Question 25 of 100
JPEG is an international standard for compressing still images, especially continuous-tone photographs. It commonly uses lossy compression to achieve much smaller files by discarding visual detail in a controlled manner, with quality selected according to the intended use.
Answer (b)
Why not others:
- BMP is an image file format that is often uncompressed or uses simple compression
- MPEG primarily standardizes moving-picture and associated audio compression
- PCM represents sampled audio signals without being a still-image compression standard
Key rule: JPEG is associated with still images, MPEG with moving media, and PCM with digital audio samples.
