The document summarizes the basic stages of information processing in a computer system. It discusses the stages of input, where information enters the system through devices like USB drives; output, where processed information leaves the system through devices like disc drives; memory, where the system stores information until the storage is full; and the information processor, which performs all calculations and problem solving. It then describes the stages of decode, where information is processed; fetch, which retrieves information for decoding; and execute, where final processing occurs before the information completes its flow through the system.
