The document discusses the clock cycle and clock in a computer processor architecture. It defines the clock cycle as the amount of time between pulses from an oscillator that determines a processor's speed. A higher number of pulses per second allows a processor to process information faster. The clock regulates and synchronizes the timing and speed of all computer functions through a crystal that vibrates at a specific frequency when electricity is applied. The CPU uses clock signals from the internal clock to execute instructions over fixed numbers of clock cycles in a synchronous manner.
