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.
A constant is a type of variable whose value cannot be changed once it is initialized (e.g., using 'const' in JS or 'final' in Java).
