40. External Peripherals of a Computer systems are the following: -> Keyboard – this is an input device -> Mouse – This is an input device also -> Printer – this is an output device -> Flashdrive – This is a storage device -> Monitor – this is an output device -> external hard drive – this is a storage device Output device are those devices that communicate the results of the data processing to the user Input device are those device that communicate the results of the data processing to the computer system Storage device are those device that stores data.

Answer:

water temperature gauge sensor

Explanation:

We can connect a temperature sensor connected to the water and a heater or cooler sensor, we have created a program to check the temperature from the sensor.
when the water is hotter than recommended, we turn on the refrigerator and when it is cold, we turn on the heater
so correct answer is water temperature gauge sensor

While you are working on your computer, it shuts down unexpectedly, and you detect a burning smell. When you remove the case cov

Virty [35]

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.

Why should you limit what information is in your digital footprint?

oee [108]

Answer:

Your “digital footprint” includes all traces of your online activity, including your comments on news articles, posts on social media, and records of your online purchases. When you know the boundaries of your digital footprint and take steps to contain it, you can help protect your identity and your reputation.

AveGali [126]

Answer:

D. Low-level components are combined into clusters that perform a specific software sub-function

Explanation:

Normally, regression testing are done on a manual basis by simply re-executing a subset of the entire available test cases or it can be done automatically by utilizing playback tools or automated capture. Hence, from the options, a combination of low-level components into clusters that perform a specific sub-function does not align with how regression testing are done either manually or automatically.
