A variable is a named storage location in the computer's memory used to hold data that can be modified or accessed during program execution.
RAM (Random Access Memory) is the computer's short-term memory where it stores the variables and data for programs that are currently running.
In languages like C++, it will hold random 'garbage' data from memory. In Java, it will throw an error or default to zero. In Python, variables must be initialized to exist.
