(Look the definitions and uses up on google as that is what the question asks)
Computer-aided design(CAD)- A way to create 2D drawings or 3D models online of real products before they are manufactured.
Computer-aided manufacturing(CAM)- The use of computer systems to plan and control the operations of a manufacturing process.
How are they used?- CAD has helped people involved in the engineering, architectural, and construction industry as well to help them visualise the things or structures they are going to make beforehand.
CAM is used with CAD usually, allowing machines such as 3D-printers or laser-cutters to create objects from the digital designs created.
How do they relate to the ideas presented in the chapter?
CAD and CAM are some real-life examples of computational models. With CAD, you are essentially creating a digital model of an object, a model which has not been created yet allowing you to experiment directly on it and helping with the construction of the system. This links to the idea of $computational$ $steering$ which was presented in the chapter, in which the digital system is tested continuously to find all flaws and fix them before the system is actually implemented or created in real life, like with CAM.
