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:
B
Explanation:
User Acceptance Testing (UAT) is the testing done by end users who is going to use that application. In these testing they will test whether the application meets all the functional requirements of the end user. If it passed then only the application will move to the production. This will ensure that the application meets the user requirements before it put into the usage.
The Answer is B
Answer:
"Recoverability" is the appropriate solution.
Explanation:
- The above refers to either the DBMS work timetables where only certain processes are conducted out only when all transactions where such modifications are learned by the submission are implemented or operated.
- This technique is used to reinstate make informed even without system failures.
