Which is the meaning of lossy and lossless compression?

A lossy compression involves a loss of information compared to the original signal; therefore it is not possible to reconstruct the original signal from one that has been compressed by using a lossy compression algorithm. Vice versa, a lossless compression does not involve a loss of information and allows a perfect reconstruction of the original signal after the decompression.
