2. Input vs Output Some hardware devices are used to input instructions into a computer. Others are used to output data. Find images of some input devices and output devices and place them in the relevant column Input Output

3. Processor A computer takes an input, processes it and produces an output. The processor in a computer is known as a CPU An example is: INPUT: User enters a number (10) PROCESS: Multiply it by 5 OUTPUT: Computer displays the answer 50 on the monitor Sometimes the result of a process is stored for later use rather than being OUTPUT. Software programs are also loaded from storage. Other than typing letters and them appearing on the screen, what other INPUT-PROCESS- OUTPUTS can you think of?
