What is the difference between fixed and variable length coding?
Fixed-length coding uses codes of the same length for all symbols, while variable-length coding uses codes of different lengths.
Can you give me an example of each?
Sure! In fixed-length coding, ASCII uses 7 or 8 bits for each character. In variable-length coding, Huffman coding assigns shorter codes to more frequent symbols.
What are the advantages of using variable length coding?
Variable-length coding can be more efficient in terms of space, as it uses shorter codes for more common symbols, reducing overall data size.
Are there any downsides to variable length coding?
Yes, variable-length coding can introduce complexity in encoding and decoding processes, and it may require additional information to determine code lengths.
