All the above terms refer to temporary memory of the computer. Cache refers to the temporary storage of the computer, where data is stored for rapid and frequent access. A buffer is also a temporary storage area on the RAM of a computer, but it is used to hold data in the CPU for manipulation before transfering it to a device such as while using MS word or burning a disc. A register is also a storage space on the CPU, but is usually used where the contents are required to be accessed more quickly. Latch is an electronic circuit that stores only one bit of memory. Whereas the term Memory refers to storage of data on a computer or a device for any interval of time.

A latch is a digital IC which holds the data put into it, 1 or 0, until cleared.

A buffer is either analog or digital, and it increases the power of the input signal without changing the value. That is, a digital buffer may be used to increase the fanout of a CMOS IC, which has a limited output power. And an analog buffer will increase the output power of a small signal, effectively lowering the output impedance.

I found definitions for all these terms at techweb. It's very good, but you have to go back to the "Tech cycoopedia" page (the one that this link goes to) after every individual search, otherwise you get taken on somewhere else.

Latch remembers the last state it was told to with another latching signal

ยท A buffer merely strengthens a signal so that it can be fanned out with integrity or drive a heftier device. Any amplifier is a buffer. It outputs a state only as long as the state persists on its input(s).

Buffer is not a part of RAM as described and function of REGISTER and RAM is same??for fast and quick access.....?
