The two devices in a computer that should be considered "black boxes," and should never be opened due to risks involving charged capacitors are MONITOR and POWER SUPPLY.
Explanation:
- Physical contact or close proximity to the open power supply caused a discharge from the capacitor that resulted in an electric shock. Capacitors can discharge current even when not energized because they hold a charge for some time after the power is turned off.
- To do harm to your body, the voltage across the capacitor's terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common 'rule of thumb' is that DC up to 48 Volt is considered low voltage. So a capacitor charged to a voltage below 48 V is fairly safe.
- A charged capacitor can be very dangerous, so it's important that you avoid coming into contact with the terminals at all times.

Answer:
Routers
Explanation:
Essentially a router is a device used in networking that route packets of data from one computer network to another.
The feature in which when once has activated can’t be
disabled without having it to be reinstalled in all of the domain controllers
inside the forest is the Active Directory Recycle Bin. The Active Directory
Recycle Bin is responsible for having to minimize the service directory by
having to enhance the ability of preserving and to restore deleted objects
without being able to restore it with the use of the active directory data.
