a. 15 + -6 = 1111 + – 110 = 1001
b. 34 + -52 = 100010 + - 110100 = -10010

5. Difference
- Lossy File Compression: mostly associated with images files, it also be used for audio
files. An original image which has been compressed using lossy format, will retain
about 80% of it’s original quality.

    • Lossy File Compression: mostly associated with images files, it also be used for audio files. An original image which has been compressed using lossy format, will retain about 80% of it’s original quality.
  • Lossless File Compression: Using lossless format can end up reducing a file’s size without any loss of the original quality. Lossless compressed files are preserved better.

  2. It means the color is purple
  3. Sample rate as the number of electronic snapshots made of the sound wave per second. Higher sample rates result in higher sound quality because the analog waveform is more closely approximated by the discrete samples.
  4. Video compression uses modern coding techniques to reduce redundancy in video data. Most video compression algorithms and codecs combine spatial image compression and temporal motion compensation
