- INPUT (PROMPT BY USER)
- PROCESS
- OUTPUT
- CONTROL UNIT
COMPUTER ORGANIZATION
The physical arrangement of a computer’s component and how they work together to perform tasks.
COMPUTER ARCHITECTURE
The structure of a computer system, including its components and how they interact to perform tasks

What is CPU (Central Processing Unit) ?
Controls the operation of the computer and performs its data processing functions: referred to as processor

- Data Processing ?
Data processing is the task of manipulating and converting raw data into useful information. This can include calculations, sorting, or changing the format of data.

- Data Storage
Data storage refers to saving data for future use, either temporarily (in RAM) or permanently (on hard drives, SSDs, or cloud storage).
Example:
Saving a document on your computer so you can open it later.

- Data Movement
Data movement involves transferring data between devices (input/output) or over long distances (data communications).
Example:
Input: Typing on the keyboard (data moves into the computer).
Output: Printing a document (data moves from the computer to the printer)/

- Control
The control unit manages and directs the computer’s resources, ensuring all parts of the computer work together to carry out instructions.
Example:
The control unit tells the computer to open a program when you click on it.
