Answer: The DATE datatype give us the particular date whereas TIMESTAMP gives us the date as well as the time as the particular moment.
Explanation:
DATE datatype gives us the date in the format yyyy-mm-dd. The timestamp format is yyyy-mm-dd hh:mm:ss. time stamp are of two types :
timestamp with time zone and timestamp without time zone.
Date is the date on that particular day whereas the timestamp is the date along with the specific time when the query is executed.
It’s a lot of reading sorry can’t help you but try your best too
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.
The answer B. a switchboard
Correct answer: Neither
The CPU<span> is also known as the </span>processor<span> or microprocessor. The </span>CPU<span> is responsible for executing a sequence of stored instructions called a program. This program will take </span>inputs<span> from an </span>input<span> device, process the </span>input<span> in some way and </span>output<span> the results to an </span>output<span> device.</span> It is neither an input nor an output device, but it is usually connected to both kinds of devices.
Output devices like your monitor, speaker, and printer does not process anything fo it to be categorized as a processing device like your CPU and so as input devices like your mouse, microphone, and keyboard.
