A user is troubleshooting a mobile device app that is displaying errors and has contacted the app manufacturer’s technical suppo

rt team for assistance. The support technician needs specific information from the device about how the app is responding and what is happening to cause the errors. How can the technician retrieve the requested information from the user’s device?

Answer:

The answer is "The user uses the method for retrieval, which is dependent on the specific app or devices on the operating system".

Explanation:

For retrieving the requested information of the form, with the user device, he uses the retrieval method, which is based upon the specific application or system operating system.

  • In this, the user can resolve the mobile phone application but also show the errors which have been committed to the assistance team of the application manufacturer.
  • Its repair technician requires detailed system data on the way the software responds and also what triggers the mistakes.

1.Electromagnetic waves can carry more data at higher frequencies. Why would a scientist opt to transmit data at a lower frequen
skad [1K]
1)The reason as to why scientists opt to transmit data at lower frequency  instead of electromagnetic even if it can carry more data at a higher frequencies is because using higher frequencies of electromagnetic spectrum travel shorter distances but have higher data carrying capacity.So this physical characteristic of electromagnetic waves limits the range and availability of frequencies for sending information.
2) Limitations of using electromagnetic waves in sending communication
communication is a process of transmitting and receiving information in the form of signals.high technology communication use electromagnetic waves,there are various types of electromagnetic waves which are used in communication which include radio-waves,microwaves,infrared  e.t.c some of their limitations are
i)Because there is limited number of broadcast frequencies the use of transmitters must be restricted  in some way or they will seriously interfere with each other.
ii)Through the air signals can be distorted by atmospheric conditions and signals from space are sometimes distorted by solar activity
iii)physical activities such as mountains and buildings can prevent or interfere with some transmissions
iv)Through the air signals are not private,so any tuned receiver within the range can pick up them.
3)Differences between digital and analogue signals
Analogue and digital signal are used to transmit information usually through electric signals.
An analogue signal is continuous wave denoted by sine wave and may varry in signal strength (amplitude) or frequency(time) an example is sound from human voice is analogue because waves are continuous..
A digital signal is a signal in which the original information is converted into a string of bits before being transmitted .example a must for computer processing where is described as using (0s and 1s)and therefore can not take any fractional value.
4)Advantages of using digital signals over analogue signals
one advantage of digital signals are inherently less susceptible than analog signals to interference caused by noise because with digital signal it is not necessary to evaluate precise amplitude,frequency or phase.
Another advantage based in capacity is that digital signals carry more information per second than analogue signals.
Digital signals maintain their quality over long distances better than analogue signals.
5)How we use digital and analogue signals in our everyday live
digital signal processing is the way of life of current generation 
example is mobile phones do alot of digital signal processing .they process our our speech digitally to remove background noise,echo  e.t.c
Television also do a lot of digital processing of video,audio signal to present them in a better way.
How radio telescopes are used to explore space
A radio telescope is a specialized antenna and radio receiver used to receive radio waves from astronomical radio sources in the sky in radio astronomy.It has several main parts, a dish and antenna,a receiver,a detector and an analyzer.The dish collects the radio signals from space ad focuses them on the antenna.
6)How radio waves are used on earth
Radio waves are used to transmit television and radio programs They have longer wave lengths and are reflected by the ionosphere
7) Reasons why telescopes convert radio waves (analog) to electrical(digital) signals for analysis
This is because signals can be easily stored and transmitted in digital form.The analog is continuous in time and it is necessary to convert this to a flow of digital values.

Which of the following statements is true for DMA: (only one correct answer) A. In DMA, Processor checks status until the operat
Ronch [10]

Answer:

<u>D. In DMA, interrupt is sent when the task is completed</u>

Explanation:

Note, the term Direct Memory Access simply refers to a computer feature that allows hardware subsystems to directly access the main system memory of a computer, without any the aid of the central processing unit (CPU).

It is a fact that while the transfer process is ongoing, an interrupt (interrupt signal) is not sent until when the task is completed.

pychu [463]

Answer:

The answer is TRUE. It is a TRUE statement.

Explanation:

Multivariate analysis is the analysis of simultaneous interactions between several variables. If two items are very correlated, they could all be included in the same index.

In the case above, what just comes to  mind as part of the process is option d.

<h3>What is sniffer?</h3>

A sniffer is known to be a kind of a software or hardware tool that gives room for a person to be able to “sniff” or look through one's internet traffic in real time, getting  all the data flowing to and from a person's computer.

Therefore, In the case above, what just comes to  mind as part of the process is option d.
