What is an algorithm?

A step-by-step process where raw data is converted into refined data through logical instructions to solve a problem.

What is a flowchart?

A diagram that shows an algorithm using standard symbols and arrows to represent control flow.

What is pseudocode?

Pseudocode means "false code"; it's a way to write out an algorithm in structured English before actual programming.

What is a program?

A set of coded instructions written in a programming language to perform a specific task.

What is source code?

Human-readable code written in a high-level language like Python.

What is machine code?

Binary code (0s and 1s) that a computer can directly understand and execute.

What is a compiler?

What are relational operators?

What are logical operators?

Operators like AND, OR, and NOT used to combine or reverse conditions.

What is iteration?

What is a FOR loop?

A loop that repeats instructions a set number of times.

What is a WHILE loop?

What is a subroutine?

What is a function?

What is a parameter?

A value passed into a function to be used in its operation.

What is a return value?

The result a function gives back after it finishes.

What is looping in text-based programs?

Using loops like FOR and WHILE in languages such as Python to repeat instructions.

What is an infinite loop?

A loop that never ends because the condition is always true.

What is a condition?

A logical expression that decides whether code runs or not.

What is an iteration variable?

The variable that changes during each loop cycle (e.g., i in for i in range).
