A Data Transfer Object (commonly known as a DTO) is usually an instance of a POCO (plain old CLR object) class used as a container to encapsulate data and pass it from one layer of the application to another. You would typically find DTOs being used in the service layer to return data back to the presentation layer. The biggest advantage of using DTOs is decoupling clients from your internal data structures.
