Sequential circuits rely on a system clock, a crystal oscillator that emits a steady pulse billions of times per second (measured in Gigahertz). This clock synchronizes the movement of data through the memory elements, ensuring calculations do not overlap or corrupt. 3. The Brain: Processors (CPUs)
Individual logic gates are combined to form that can perform specific functional tasks.
In physical hardware, these gates are constructed using acting as electronic switches. 2. Digital Circuits: Combining Gates for Functionality
