Question

1. (02.02 mc) which type of data compression is run - length encoding? (2 points) lossy, because the data can be restored to its original values. lossless, because the data can be restored to its original values. lossy, because the data cannot be restored to its original values. lossless, because the data cannot be restored to its original values. 2. (02.02 lc) which type of file typically only uses lossless data compression? (2 points) image video

Explanation:

1. Run - length encoding is a lossless data compression technique as the original data can be exactly restored from the compressed data. Lossy compression discards some data and cannot fully restore the original.
2. Text files typically use lossless data compression. While images and videos can use both lossy (e.g., JPEG for images, MPEG for videos) and lossless compression, text needs to be exactly reproduced, so lossless is preferred.

Answer:

1. Lossless, because the data can be restored to its original values.
2. Text (not given in options, but typically true; if we must choose from given options, neither image nor video is correct as they can use lossy compression too)
