Why the Process Matters to Techs
The commonality of devices allows one to work on any device with some patience

5. The Computing Process Breaking It Down Power up.
Processing parts prepare for action
You provide input
Processing parts process your command
Processing parts send output information to your output devices
Output devices show you the results
Repeat steps 3 – 6 until you’re satisfied with the outcome
Save your work
Power down the computer
