Document Summary
Random access media-non-sequential parts of a computer memory which can be called up as if they were next to each other. Creates more complex relationships between sensed events and caused events. Creates a rich conversation between physical world and the virtual world of the computer. Transduction-the conversion of one form of energy into another. Transducers-devices which will convert between physical energy and electrical energy. Interaction-an iterative process of listening, thinking, and speaking between two or more actors. Processing: proximity sensor, switch a person steps on. Input, processing, and output has to do with energy flow. It takes less energy to sense activity than to move things. Processing requires a computer to read the input, make a decision and activate an output. Electrical current can flow through components serially or in parallel. Computers can exchange bits of information serially or in parallel as well. Building a project using a computer system: describe first what you want to happen.
