Which computer component contains the physical quartz crystal oscillator that vibrates at a precise frequency to generate clock timing pulses for the system?
Answer and explanation
Correct answer: D. Clock generator
- Step 1: Synchronous digital electronics require a periodic reference signal to coordinate the state transitions of millions of flip-flops.
- Step 2: The clock generator uses the piezoelectric properties of a quartz crystal that oscillates at a fixed frequency when electrical voltage is applied, providing the base clock for PLL frequency multiplication.
Answer
Clock generator
Why not the others: 'Digital-to-Analog Converter (DAC)' A DAC converts discrete binary values into continuous analog voltage signals for audio or analog displays; 'Voltage Comparator' A comparator compares two electrical voltage levels and outputs a digital flag indicating which is higher; 'Linear Regulator' A linear regulator steps down voltage by dissipating excess energy as heat, rather than generating oscillating timing clocks.
