difference between buffer and latch

A buffer is a device that provides additional current drive capability, typically used in bus driving aplications. Buffers are available in either inverting or non-inverting applications. They are frequently available with 3-state outputs, so that their outputs can be removed from the bus that they are driving. Buffers can be either unidirectional or bidirectional. Bidirectional buffers have an additional input to determine which end is the input/output.
A latch provides a means to "capture" the input data at a specific time via the use of a clock (for edge triggered applications) or a strobe input (for level triggered applications)

Regarding your question about buffers and latches; in case of a buffer, the ouput signal equals the input signal and so if the input exists then the output exists and vice versa.
In case of a latch, if the input is now existent then the output exists; if you now remove the input the output will still exist.
I hope this is OK for you.

buffer take the voltage level on appropriate logic level..
latch store data temporarily..
