  • Also called the "Microprocessor."

  • The "Brains" of the computer.

  • Basic operation performed by a central processing unit (CPU).

Main Parts:

  • The instruction Cycle (I-Cycle)
  • The Execution Cycle (E-cycle)

  • Sometimes called a "Fetch-Decode-Execute Cycle."
  • The basic operational process of a computer
  • The instruction cycle is the amount it takes to retrieve instructions to perform a specified task and complete the command.
            - Determines what actions the instruction dictates and carries out those actions.

  • The execution cycle refers to the amount of time it takes the CPU to execute the instruction and store results in RAM.
            - Performs/obeys the instructions.

  • The arithmetic unit performs arithmetic computations and logical operations.
            - Arithmetic computations include addition, subtraction, multiplication, and division.

  • The logic unit involves comparisons
            - Asks the computer to determine if two numbers are equal or if one number is greater than or less than another number.

  • The ALU executes commands.

  • The control unit coordinates all of the processor's activities.

  • It manages the flow of information through the processor by controlling what happens inside it.
            - Decodes the instructions and controls all the other internal components. It's what makes it work

  • Changes the instruction into machine language.
           - Uses binary code, which contain only 1's and 0's.
