Explanation:
Detailed explanation-1: -Run-Length Encoding (RLE) Encoding this with a 3-bit count and the 1 bit value, the encoding is 0-110 1-111 1-100 0-111 The compression ratio is (24-16) / 24 = 1/3. RLE is lossless. RLE is good for compressing images with large uniform areas (scanned text: 8-to-1 compression).
Detailed explanation-2: -RLE is a simple method of compressing data by specifying the number of times a character or pixel colour repeats followed by the value of the character or pixel. The aim is to reduce the number of bits used to represent a set of data.
