Data compression reduces the amount of space needed to store data or reducing the amount of time needed to transmit data. Data compression is defined as the science and art of the representation of information in a crisply condensed form. For decades, data compression is considered as critical technologies for the ongoing digital multimedia revolution. There are variety of data compression algorithms which are available to compress files of different formats. This paper provides a survey of different basic lossless data compression algorithms such as LZ77 and LZ78.
