Study Notes
Computer Processing Unit
- Central Processing Unit (CPU): Converts data into information, acts as the control center, and executes stored program instructions.
- CPU consists of two parts: Control Unit (CU) and Arithmetic Logic Unit (ALU).
Control Unit (CU)
- Regulates and integrates the operations of the computer.
- Directs the computer system to execute stored program instructions.
- Communicates with other parts of the hardware.
Arithmetic Logic Unit (ALU)
- Performs arithmetic operations: +, -, *, /, and others.
- Performs logical operations: NOT, AND, OR, =, >, <, and others.
Arithmetic Operations
- Addition: Combines two or more numbers to get a total or a sum.
- Subtraction: Finds the difference between two or more numbers.
- Multiplication: Repeats the addition of a number a certain number of times.
- Division: Divides a number into equal parts or groups.
Logical Operations
- NOT: Evaluates conditions, makes comparisons, and returns a true or false value.
- AND: Compares two or more conditions, numbers, letters, or special characters, and returns a true or false value.
- OR: Compares two or more conditions, numbers, letters, or special characters, and returns a true or false value.
- Comparison operators: =, >, <, >=, etc. compare values and return a true or false value.
Components of Computer
- Input Unit: Receives input, accepting information from the outside world.
- Processing Unit: Performs arithmetic or logical operations on information.
- Output Unit: Communicates information to the outside world.
- Storage Unit: Stores and retrieves information from memory and storage devices.
Input Unit
- Examples of input devices: keyboards, mouse, scanners, cameras, joysticks, and microphones.
Output Unit
- Examples of output devices: text, graphics, tactile, audio, or video displays.
- Output devices convert information into a human-perceptible form or a physical machine-readable form.
