| Investigate the Control Unit(CU)? |
|
Definition
}The control unit is basically circuitry inside the CPU, controlling the operations inside the CPU and "directing traffic" in a sense. The functions a control unit performs can depend on the type of CPU, since the varying degrees of architecture between all the different CPUs will determine the functions of the control unit. |

| Investigate the Arithmetic Logic Unit(ALU) |
|
Definition
| The ALU performs specific operations such as addition, multiplication, and conditional tests on the data in its registers, sending the resulting data back to RAM or storing it in another register for further use. During this process, a unit called the program counter keeps track of each successive instruction to make sure that the program instructions are followed by the CPU in the correct order. |

- Clock Speed
The clock speed of a CPU is defined as the frequency that a processor executes instructions or that data is processed.
- This clock speed is measured in millions of cycles per second or megahertz (MHz).

Core: Cores are what handle the arbitrary mathematical and logical workloads. They take high level machine instructions (x86, ARM, MIPS, etc...) and 'decode' them into physical circuit operations.
