hardware A low-level digital logic component. Gates
perform Boolean functions (e.g. AND, NOT), store
bits of data (e.g. a flip-flop), and connect and
disconnect various parts of the overall circuit to control the
flow of data (tri-state buffer).
In a CPU, the term applies particularly to the buffers that
route data between the various functional units. Each gate
allows data to flow from one unit to another or enables data
from one output onto a certain bus.
