Can you explain variable length coding?
Sure! Variable length coding is a method of encoding data where the length of the code for each symbol can vary. This is often used in data compression.
How does it differ from fixed length coding?
In fixed length coding, each symbol is represented by the same number of bits, while in variable length coding, more frequent symbols can be represented with shorter codes, saving space.
Can you give me an example of variable length coding?
A common example is Huffman coding, where symbols are assigned shorter codes based on their frequency in the data set.
What are the advantages of using variable length coding?
The main advantage is improved compression efficiency, as it reduces the overall number of bits needed to represent the data.
