difference between sampling and quantization

hii frends.....
I still can't be able to make a difference between sampling and quantization..i mean i have read a lot on both of them....i mean books says that sampling's only time discrete and quantization's both(time-amplitude discrete)....but still m confused....
plzz help me out..
thanks!!!
 

difference between quantization and sampling

sampling discretizes the signal in time and quantization discretizes in amplitude-
 

difference between quantization and sampling

When you sample a continous signal (a continous signal is something like sin(w*t), you can find its value for any time t), the signal exists only at the sampling instant (like t=1s, 2s, 3s, ...). Else the signal is not zero, but doesnt exist.

The signal can be quantized, which means that the signal is now restricted to have a few voltage levels only (like V=±1v, ±2v, ±3v, ...).

When both are done, the signal can have only discrete values and exists at discrete times only.
