Which two components in a system might make a loud whining noise when there is a problem? Why?

1 answer:

5 0

The power supply and the Hard drive are the two components that makes loud whining noise when a problem is detected.

Explanation:

Computers can undergo what's called “coil whine,” which is a high-pitched noise that originates from the computer.
coil whine is an unacceptable noise emitted by an electronic component vibrating as power runs through an electrical cable.
It's easy to infer that the noise is an indication of influential computer malfunctioning or that something is cut, disconnected, or about to collapse.
It is normally caused by an electrical current passing through a power-regulating component like a transformer or inductor, inducing its electrical wiring to vibrate at a shifting frequency.
Luckily, coil whine is normal behavior.

The IPv4 address scheme has enough IP addresses to give every blade of glass in the world its own unique IP. True False

Andrew [12]

Answer:

False

Explanation:

IPv4 address are composed of four octets (8 bit numbers), ranging from 0.0.0.0 to 255.255.255.255

All those 32 bits, in decimal notation, can form a total of

$2^{32} = 4,294,967,296$ different addresses.

Being more than 4 billion addresses and ignoring that some addressesare reserved for special uses, even present human population almost doubles that number.

So it is safe to state that IPv4 addresses is not enough to give every blade of grass its own IP.
