Clocking
The motherboard generates a clock signal that is used to control the transfer of 1s and 0s to and from the processor. A clock signal can be illustrated as a sine wave. One clock cycle is from one point on the sine wave to the next point that is located on the same point on the sine wave later in time, as shown in Figure 3.8.
)
Figure 3.8 Clock cycle
In older computers, data was sent to the CPU only once during a clock cycle. Then, newer memory technologies evolved that allow data to be sent twice during every clock cycle. Today, data is sent four times during a single clock cycle, as shown in Figure 3.9.
