Compression refers to reducing the quantity of data, bits used to represent, store and/or transmit file content, without excessively reducing the quality of the original data. Data compression technique can be lossless which enables exact reproduction of the original data on decomposition or lossy which does not. Text data compression techniques are normally lossless. There are many text data compression algorithms, and it is essential that best ones be identified and evaluated towards optimizing compression purposes. This paper focused on proffering key compression algorithms, and evaluating them towards ensuring selection of better algorithms over poorer ones.
