Answer:
C. Dow Jones
Explanation:
It’s the Dow Jones certainly, and we also know it as Dow 30. You will find with a little research that Dow Jones is an index of the 30 carefully chosen blue-chip stocks, and general industrial stocks. And this is price prejudiced average, and of 30 stocks that can be well-thought-out as an all-purpose measure for the whole stock market performance.
Answer: A) Battery backup
Explanation:
A battery backup are used to provide the source of power backup to various hardware components and desktop computers. In many cases, the devices are plugged into UPS ( uninterruptible power supply) for backup power and it is also depend upon the size of the UPS.
All the battery backups are located inside so that is why, the devices are heavy in weight. Usually, the battery backup front required additional button for performing various functions.
And the battery backup devices are manufacture by using the varying degree of backup abilities.
Answer:
Replace the power supply
Explanation:
Usually, Capacitors burn up because of different factors.
- Exceeding operation voltage
- High Inverse voltage if is an electrolytic capacitor.
A tentative answer could be the battery, but usually the batteries damages are because wear out of them, that is, cycles of charging and discharging, a problem that could arise in the battery is related with the charge protection, this circuit cares that the battery only get the charge that it needs, in Li-po batteries is 3.7V, in some laptops is 24 V, if so the battery could explode or leaking acid.
The mother-board is the "brain" and the Random Access Memory (RAM), they consume a lot of energy and usually heat up, but doesn’t produce increasing of voltage and its feed it by voltage regulators.
The only valid option is the power supply because the energy comes from a rectifier (made with diodes) and a voltage regulator that step-down the DC voltage output if by any chance the voltage increase or a diode burns up in the power supply the coupling capacitors or input capacitors in the computer will fail.
