Today we visited Escola secundaria de Barcelos. Our knowledge about the structure and functioning of PC were tested by our trainer, who gave us an initial test. Then we learnt how to use the platform "miro" so that we could work with our schoolmates on a project test gave by him. After that Marco presented us the components of a computer and told us what every piece does and how the computer works as a whole. Then we got a project to choose a component and explain what it does and other informations about it. so at the end of the day we know how to identify computer components, distinguish types of computer cases and power sources, identify and explain the roles of motherboard, microprocessor, cooling systems.
