The Clock

Clock pulses are generated by the clock generator in the motherboard.

Clock Pulse/Tick & Clock Cycle/Period

1 Hz is equal to 1 cycle per second. If a single cycle is 1/50 of a second in duration (0.02 seconds), then there will be 50 cycles in a second (1 / 0.02). We say the frequency is 50 Hz.

Pulses/Ticks are often half the cycle/period wide, what is called 50% duty cycle. A 1 MHz signal has a 1 µs period, then the clock pulses will often be 0.5 µs wide.
