WebA buffer allows a signal to drive more inputs than it would by itself, or provides input protection / amplification. For the 8086, it's used in the output sense, allowing internal signals to be made robust to drive external devices. A latch is a circuit to accept and store one or more bits, with a 1-to-1 input / output ratio. Webmove the data in the WC buffer it must make a bus transaction style decision based on how much of the buffer contains valid data. If the buffer is full e.g. all 32 bytes are valid, the processor will execute a burst write transaction on the bus that will result in all 32 bytes being transmitted on the data bus in 4 bus clocks.
