Which one of the following basic operations for converting raw input data into useful information is not performed by all computers?
Knowledge of Computer ApplicationsComputer fundamentals
- AInputting
- BStoring
- CSwitching
- DOutputting
Explanation
The basic data-processing cycle of every computer is input → process/store → output: raw data is input, stored and processed, and useful information is output. Inputting, storing and outputting are therefore performed by all computers. “Switching” is not a data-processing operation at all. Hence (C) switching is the one not performed.
