Messages and methods are key concepts in object-oriented programming (OOP).

1. Messages: In OOP, objects communicate with each other through messages. A message is a signal from one object to another requesting that it executes one of its methods. It can include additional information needed to perform the method. Essentially, sending a message is like calling a method.

2. Methods: A method is a block of code that is defined within a class and represents a particular action or behavior of an object of that class. When a method is invoked, it performs a specific task. Methods can take parameters, which are used to pass values to the method when it is called. They can also return a value to the caller.

For example, consider a class 'Dog'. This class might have a method 'bark'. An object of the class 'Dog', let's call it 'fido', can receive a message 'bark'. When 'fido' receives the 'bark' message, it will execute the 'bark' method, resulting in the dog barking.
