Electronic systems and programmable components

the interconnected parts of a system that can be classified as inputs, outputs and processes

the small sections of a push button system

the tiny sections of outputs that control an even smaller system

the matching parts of a small system that can be linked to inputs, processes and outputs

Switch

Counting - keeping track of scores in a sports game and displaying them on a electronic board

Switching - switching on a streetlamp when the light level falls

Timing - security light for a period of time after movement is detected

Noise - being turned on when the noise level is too loud and being turned off when the noise level is low

It improves the control function of the sytem

It creates white noise so that the system is louder

It makes the system work slower so that it is easier to control

It improves the colour of the system so that it is less boring
