Ruby provides four types of variables: local variables, instance variables, class (or singleton) variables, and global variables.n- Local variables are used within methods and blocks. They start with a lowercase letter or an underscore (").n- Instance variables are variables that belong to instances of a class. They start with '@'.n- Class variables are shared among all instances of a class. They start with '@@'.n- Global variables are variables that can be accessed from anywhere in the program and are prefixed with $.
