You simply need to understand the process of sampling and quantizing.
The compact disk standard sampling rate is 44.1 kHz. To state it simply, that means the audio is sampled 44,100 times per second.
The compact disk quantization standard is 16-bit. That is, 16 binary bits are used to measure the amplitude and polarity of the audio waveform per sample.
The only other thing you should know is the Nyquist theorem which states that a sampling rate can recover any frequency up to half of said rate. So, on paper this means a compact disk can play back frequencies up to 22.05 kHz.
If you can understand this, you can grasp that there can be different sampling rates, and different quantization levels (bit depths).
