Run-length Encoding (RLE) uses which kind of compression?
A
Lossy
B
Lossless
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Run-length encoding (RLE) is a form of lossless data compression in which runs of data (sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. This is most useful on data that contains many such runs.

Detailed explanation-2: -Run-length encoding (RLE) is a lossless compression method where sequences that display redundant data are stored as a single data value representing the repeated block and how many times it appears in the image. Later, during decompression, the image can be reconstructed exactly from this information.

Detailed explanation-3: -August 12, 2021. Run Length Encoding is a lossless data compression algorithm. It compresses data by reducing repetitive, and consecutive data called runs. It does so by storing the number of these runs followed by the data.

Detailed explanation-4: -Run-length encoding (RLE) is a very simple lossless compression algorithm. It works by taking runs of repeated data and storing them as single values. A simple analogy for RLE is the directions you give to someone while they are driving a car.

Detailed explanation-5: -Lossless compression uses an algorithm to shrink the image without losing any important data. Essentially, it rewrites the file to make it more efficient-resulting in a smaller storage or transfer size. One way the algorithm does this is by replacing non-essential information and storing them in an index file.
