Computer Science for IGCSE & O level - Data Representation (Section 14 - No. 39)
What is the primary disadvantage of using run-length encoding (RLE)?
It is a lossy compression technique.
It is only effective for very simple images.
It always results in a larger file size than the original.
It requires significant processing power to implement.
Explication
RLE is most effective for data with long repeating sequences. It's not efficient for images that lack such patterns.
