When you first declare a variable in statically typed language such as C++ you must declare what that variable is going to hold.

int number = 42;

In that example the "int" is a type specifier stating that the variable "number" can only hold integer numbers. In dynamically typed languages such as ruby or javascript you can simply declare the variable.

number = 42

Edit to add: There's a pretty good StackOverflow post on the difference between static and dynamic and strong vs weak variables in languages.
