or latch, which stores one bit of memory. When you click the set input, it goes low, and
this brings the Q output high, even after the set input goes high again. When you click
the reset input, it goes low, and this
brings the Q output low. If set and reset are high, then the output stays the same as
when it was last set or reset.
