Abstract :
We are proposing enhancements in one of the most popular data compression algorithm named LZW algorithm to increase overall performance of the algorithm. We have achieved this by applying three modification schemes to LZW algorithm. First two enhancement schemes eliminate the frequent flushing of dictionary, thus lowering processing time and third enhancement improves the compression ratio by reducing number of bits transferred over the communication channel
