3. Architecture The word "architecture" typically refers to building design and construction. In the computing world, "architecture" also refers to design, but instead of buildings, it describes the design of computer systems. The most important type of hardware design is a computer's processor architecture.  The design of the processor determines what software can run on the computer and what other hardware components are supported. The design of the processor determines what  software  can run on the computer and what other hardware components are supported.

4. Clock Cycle The speed of a computer processor, or CPU, is determined by the  clock cycle , which is the amount of time between two pulses of an oscillator. The higher number of pulses per second , the faster the computer processor will be able to process information.  The clock speed is measured in Hz, often either megahertz (MHz) or gigahertz (GHz).

5. Clock The  clock  refers to a microchip that regulates the timing and speed of all computer functions. In the chip is a crystal that vibrates at a specific frequency when electricity is applied. Another name for the internal  clock  or RTC (real-timeclock).

6. Purpose of Clock in CPU Every computer contains an internal  clock  that regulates the rate at which instructions are executed and synchronizes all the various computer components. The  CPU  requires a fixed number of  clock  ticks (or  clock  cycles) to execute each instruction.

7. CPU Use Clock Signals It's what drives the enormous synchronous clock machine called a Central Processing Unit (CPU). Inside the CPU lies the Control Unit (CU) which executes assembly instructions and the Arithmetic and Logic Unit (ALU) which performs all the math operations requested of it by the CU one clock tick at a time.
