Computer
A machine that processes information and performs computations.
Input
Information or signals entered into a computer system (e.g., keyboard, mouse).
Output
he information or signals a computer sends out (e.g., display on a screen, sound from speakers).
Processing
The action a computer takes to transform input into output.
Storage
Saving data to be used later (e.g., hard drive, cloud storage).
Abstraction
Simplifying complex systems by focusing on the main idea and hiding details.
Algorithm
A step-by-step set of instructions for solving a problem or performing a task.
Sequencing
The order in which steps or instructions are executed in an algorithm.
Iteration
Repeating a process or a set of instructions in an algorithm (e.g., loops).
Selection
Making decisions in an algorithm using conditions (e.g., if/else statements).
Procedure(function)
A named sequence of instructions that performs a specific task; can be reused in different parts of a program.
Parameters
Variables used to pass information to procedures or functions.
Return Value
The output that a procedure or function provides when it is called.
Modularity
The design principle of breaking a program into separate, reusable sections or modules.
Data
Information that is collected, stored, and processed by a computer.
