PCM is lossless and uncompressed thus taking more space, MPG is compressed thus having declined audio quality but takes less space.

Is LPCM lossless audio?
LPCM, also known as linear pulse-code modulation, is a method that is used for encoding audio information in digital form. It is commonly used for lossless encoding in a compct disc using the Red Book standard.
What is the different between linear and nonlinear pulse code modulation?
The difference between linear and non-linear PCM is LPCM represents sample amplitudes on a linear scale. LPCM specifies that the values stored are proportional to the amplitudes, rather than representing say the logarithm of the amplitude or being related in some other manner. While non-linear each step size may vary in amplitude.
