Question 1

What file extension identifies a native Adobe Photoshop document that preserves layers and editing data?

Accepted Answer

.psd

Answer

The .psd (Photoshop Document) format is Photoshop's native file type, storing layers, masks, channels, and adjustment data in an editable, non-destructive format.

Question 2

Which audio format is most widely used for streaming music and podcasts on the web due to its balance of quality and file size?

Accepted Answer

MP3

Answer

MP3 (MPEG-1 Audio Layer III) achieves significant file size reduction through lossy psychoacoustic compression while maintaining perceptually acceptable quality, making it the dominant streaming audio format.

Question 3

In digital audio production, what does 'bit depth' determine?

Accepted Answer

The number of possible amplitude values per sample, affecting dynamic range

Answer

Bit depth defines how many discrete volume levels can be represented per audio sample; a 16-bit depth provides 65,536 amplitude values, while 24-bit provides over 16 million, resulting in greater dynamic range.

Question 4

Which image file format supports the CMYK color mode required for professional offset printing?

Accepted Answer

TIFF

Answer

TIFF (Tagged Image File Format) supports CMYK color mode along with high bit depths and lossless compression, making it the preferred format for prepress and professional print workflows.

Question 5

What is the primary purpose of a media container format such as MKV?

Accepted Answer

To hold multiple streams of video, audio, subtitles, and metadata in a single file

Answer

A container format like MKV (Matroska Video) wraps multiple encoded streams—video, audio tracks, subtitles, and chapter markers—into one file without dictating the codec used for each stream.
