The given options describe different stages of a computer system. The first option states that output is a stage of a computer system, which is true as output refers to the result or information produced by the computer. The second option states that processing is a stage of a computer system, which is also true as processing involves manipulating and transforming input data to produce output. The third option states that input is a stage of a computer system, which is again true as input refers to the data or information that is entered into the computer. Therefore, the only option that does not explain a stage of a computer system is "Input - processing - output".

The components of a flowchart typically include input/output, processing, and start/end symbols. However, "network" is not a standard component of a flowchart. Flowcharts are used to represent the flow of a process or algorithm, and "network" does not fit into this categorization.
