Terminology

Branching: An instruction that tells a computer to begin executing a different part of a program rather than executing statements one-by-one

Compiler: A program that converts instructions into a machine-code or lower-level form so that they can be read and executed by a computer

Conditional statement: A statement that is created by the programmer which evaluates actions in the program and evaluates if it is true or false
